SPSx50 Modular GPS Receiver User Guide vSafety InformationBefore you use the SPS GPS receivers, make sure that you have read and understood all safety requirements.Regulations and safetyThe Bluetooth module inside the SPSx50 Modular GPS receiver, the SPSx80 Smart GPS antenna, and the ACU, TSC2, and TCU controllers is a radio-modem transmitter and receiver.Regulations regarding the use of the radio-modems vary greatly from country to country. In some countries, the unit can be used without obtaining an end-user license. Other countries require end-user licensing. For licensing information, consult your local Trimble dealer.Before operating an SPSx50 Modular GPS receiver or SPSx80 Smart GPS antenna, determine if authorization or a license to operate the unit is required in your country. It is the responsibility of the end user to obtain an operator’s permit or license for the receiver for the location or country of use.For FCC regulations, see Notices, page iii.*****Query from RobMiller - SPSx50 and SPSx80 receivers also contain internal transmit radios. Does this information apply to them as well? If not - more needs to be added here.Type approvalType approval, or acceptance, covers technical parameters of the equipment related to emissions that can cause interference. Type approval is granted to the manufacturer of the transmission equipment, independent from the operation or licensing of the units. Some countries have unique technical requirements for operation in particular radiomodem frequency bands. To comply with those requirements, Trimble may have modified your equipment to be granted Type approval. Unauthorized modification of the units voids the Type approval, the warranty, and the operational license of the equipment.Exposure to radio frequency radiationThe radiated output power of the internal Bluetooth wireless radio is far below the FCC radio frequency exposure limits.Nevertheless, the wireless radio shall be used in such a manner that the Trimble receiver is 2.0 cm or further from the human body. The internal wireless radio operates within guidelines found in radio frequency safety standards and recommendations,

Safety Informationvi SPSx50 Modular GPS Receiver User Guidewhich reflect the consensus of the scientific community. Trimble therefore believes the internal wireless radio is safe for use by consumers. The level of energy emitted is far less than the electromagnetic energy emitted by wireless devices such as mobile phones. However, the use of wireless radios may be restricted in some situations or environments, such as on aircraft. If you are unsure of restrictions, you are encouraged to ask for authorization before turning on the wireless radio.*****Query from RobMiller - SPSx50 and SPSx80 receivers also contain internal transmit radios. Does this information apply to them as well? If not - more needs to be added here.Battery safetyCWARNING – Do not damage the rechargeable Lithium-ion battery.

SPSx50 Modular GPS Receiver User Guide 21Features and Functions 2Use and careThe SPSx50 receiver is designed to withstand the rough treatment and tough environment that typically occurs in construction applications. However, the receiver is a high-precision electronic instrument and should be treated with reasonable care.CCAUTION – Operating or storing the receiver outside the specified temperature range can damage it. For more information, see Appendix A, Specifications.COCOM limitsThe U.S. Department of Commerce requires that all exportable GPS products contain performance limitations so that they cannot be used in a manner that could threaten the security of the United States. The following limitations are implemented on the SPSx50 receiver: Immediate access to satellite measurements and navigation results is disabled when the receiver velocity is computed to be greater than 1000 knots, or its altitude is computed to be above 18 000 meters. The receiver GPS subsystem resets until the COCOM situation clears. As a result, all logging and stream configurations stop until the GPS subsystem is cleared.

The battery can be replaced only at an Authorized Trimble Service Center.The receiver can also be powered by an external power source that is connected to the Lemo or modem port.The operational time provided by the internal battery depends on the type of measurement and operating conditions. Typically the internal battery provides >15 hours operation as a base station and >20 hours as a rover during measurement operations using the internal radio.<<I’ve entered the information from page 1 of the datasheet in the first part of the sentence, above - however, the operating hours on p 3 are not specified in the datasheet yet, so not sure whether this is correct. Rob says that Nick will provide information.> <<Product team. Please check number of hours listed here against number of hours listed in the Tech. Specs. chapter. Different numbers. Needs clarification>><<Note to Product team: All warnings need to be repeated in Safety Information chapter. Sorry for the duplication but it is part of our legal requirements.>>

3 Batteries and Power28 SPSx50 Modular GPS Receiver User GuideExternal powerThe external power source is always used in preference to the internal batteries. When there is no external power source connected, or if the external power supply fails, the internal battery is automatically used. In this way the internal battery acts as an uninterruptible power supply covering times of power failure. The internal battery will only charge from an external power source which delivers more than 15 volts, for example, an AC power adaptor.During static measurement data logging, if no external power is supplied and the internal battery is drained, the receiver will switch off. However, all collected data is secure. If the receiver is operating as a base station when this happens, the receiver will power down and stop transmitting corrections. When power is restored to the receiver, it will resume operation in the same status that it was in when power was lost, using the same settings as before the shut down.Battery performanceBatteries perform best when they are not used in extreme temperature conditions. The receiver is designed to be used in operating temperatures of –40 °C to +65 °C (–40 °F to +149 °F). However, extremely cold temperatures of less than 0 °C (32 °F) can cause the battery life to quickly drop. Do not expose the receiver to storage temperatures outside the range –40 °C to +70 °C (–40 °F to +158 °F).To protect the battery from deep discharge (5 V or less), the receiver is designed to switch power sources or cease drawing power when the battery pack discharges to 5.9 V. A battery that has reached the deep discharge level cannot be recharged and must be replaced. The following recommendations provide optimal performance and extend the life of your batteries:•Fully charge all new batteries before use.•Do not allow the batteries to discharge below 5 V.•Keep all batteries on continuous charge when not in use. Batteries may be kept on charge indefinitely without damage to the receiver or batteries.Battery safetyThe receiver is powered by a rechargable Lithium-ion battery. Charge and use the battery only in strict accordance with the instructions below.CWARNING – Do not damage the rechargeable Lithium-ion battery. A damaged battery can cause an explosion or fire, and can result in personal injury and/or property damage. To prevent injury or damage: – Do not use or charge the battery if it appears to be damaged. Signs of damage include, but are not limited to, discoloration, warping, and leaking battery fluid.– Do not expose the battery to fire, high temperature, or direct sunlight. – Do not immerse the battery in water.

SPSx50 Modular GPS Receiver User Guide 29Batteries and Power 3– Do not use or store the battery inside a vehicle during hot weather. – Do not drop or puncture the battery. – Do not open the battery or short-circuit its contacts.CWARNING – Avoid contact with the rechargeable Lithium-ion battery if it appears to be leaking. Battery fluid is corrosive, and contact with it can result in personal injury and/or property damage.To prevent injury or damage:– If the battery leaks, avoid contact with the battery fluid. – If battery fluid gets into your eyes, immediately rinse your eyes with clean water and seek medical attention. Do not rub your eyes! – If battery fluid gets onto your skin or clothing, immediately use clean water to wash off the battery fluid.Battery charging and storageAll battery types discharge over time when they are not being used. Batteries also discharge faster in colder temperatures. If a Lithium-ion battery is to be stored for long periods of time, make sure it is fully charged before storing and re-charged at least every three months.The SPSx50 receiver has an integrated Lithium-ion battery and the charging circuitry is integrated into the receiver. The battery is charged when it is connected to a power source delivering greater than 15 V. The receiver is supplied with a mains power supply unit that recharges the battery inside the receiver when it is connected through the adapter to the modem port or the Lemo port. When you use the receiver on large projects, from a permanent or semi-permanent base station location in a site cabin, Trimble recommends that you use this power supply at all times to keep the internal battery charged. This provides an uninterrupted power supply during mains power outages and will keep the site operational for more than 10 hours after a power failure.CWARNING – Charge and use the rechargeable Lithium-ion battery only in strict accordance with the instructions. Charging or using the battery in unauthorized equipment can cause an explosion or fire, and can result in personal injury and/or equipment damage. To prevent injury or damage: – Do not charge or use the battery if it appears to be damaged or leaking.– Charge the Lithium-ion battery only with a Trimble product that is specified to charge it. Be sure to follow all instructions that are provided with the battery charger. – Discontinue charging a battery that gives off extreme heat or a burning odor.– Use the battery only in Trimble equipment that is specified to use it. – Use the battery only for its intended use and according to the instructions in the product documentation.Charging the Lithium-ion batteryThe rechargeable Lithium-ion battery is supplied partially charged. Charge the battery completely before using it for the first time. If the battery has been stored for longer than three months, charge it before use.

3 Batteries and Power30 SPSx50 Modular GPS Receiver User GuideThe internal battery charges fully in 8 hours when connected to a suitable power source. Disposing of the rechargeable Lithium-ion batteryThe integrated Lithium-ion battery should be removed only at an authorized service center. If the battery is removed at an unauthorized service center, the remaining warranty on the product will be void. After you remove the Lithium-ion battery, discharge it fully before disposing of it. When disposing of the battery, be sure to do so in an environmentally sensitive manner. Adhere to any local and national regulations concerning battery disposal or recycling.Operating with the controller or laptop computerDuring operation, the controller will typically be connected to the receiver using the Bluetooth cable free connection. Where a serial connection is used, the receiver delivers no power through its communications ports to the controller, which must have its own source of power in order to operate.

CHAPTER4SPSx50 Modular GPS Receiver User Guide 31Setup Guidelines 4In this chapter:QBase station operation guidelinesQRover receiver operation guidelinesThis chapter introduces the concepts of base station and rover operation, provides information to help you identify good setup locations, describes best practices for setting up the equipment, and outlines the precautions that you need to take to protect the equipment.

4 Setup Guidelines32 SPSx50 Modular GPS Receiver User GuideBase station operation guidelinesFor all GPS Real-Time Kinematic (RTK) operations, you require both a base station and a rover.RTK operation provides centimeter-level accuracy by eliminating errors that are present in the GPS system. A receiver placed at a known position (the base station) tracks the satellites that are being tracked by the rover receiver, at the same time that the rover is tracking them. Errors in the GPS system are monitored at the fixed (and known) base station, and a series of position corrections are computed. The corrections are sent through a radio link to the rover receiver, where they are used to correct the real time positions of the rover.This section discusses the base station component and its role in providing an RTK solution.Base station componentsThe base station has the following components:•GPS receiver•GPS antenna•base station radio•power supplyGPS receiver and GPS antennaThe base station GPS receiver can be one of following types:•A Smart GPS antenna, such as the SPSx80 receiver, incorporates a GPS receiver, GPS antenna, power supply, and base station radio into a single compact unit. A Smart GPS antenna can be rapidly set up on a tripod, fixed height tripod, or T-Bar anywhere that is convenient on the jobsite.•A modular GPS receiver, such as the SPSx50 receiver, incorporates a GPS receiver, power supply, and base station radio in a single unit. The GPS antenna and, optionally, the base station radio antenna is separate from the receiver. Because the GPS antenna is separate, you can use the following optimized components: – a geodetic antenna with large ground plane, to eliminate multipath (the major source of GPS errors) at the base station– a high gain or directional radio antenna, to increase broadcast range and to provide maximum coverageYou can also place a modular GPS receiver in an easily accessible and secure location, safe from theft and the weather, while the antennas are placed high on a tower or building, clear of obstructions and able to deliver maximum performance.You can use either type of receiver in a permanent, semi-permanent, or daily quick setup configuration. If semi-permanent or permanent operation is required, however, the modular receiver delivers significant advantages.

SPSx50 Modular GPS Receiver User Guide 33Setup Guidelines 4Base station setup guidelinesFor good performance, observe the following base station setup guidelines:•Place the GPS receiver in a location on the jobsite where equal range in all directions provides full coverage of the site. This is more important on larger jobsites, where the broadcast range of the base station radio may limit the operations of the GPS system.•Place the GPS antenna in a location that has a clear line of sight to the sky in all directions. Do not place the GPS antenna near vertical obstructions such as buildings, deep cuttings, site vehicles, towers, or tree canopy.•Place the radio antenna as high as practical. This minimizes multipath from the surrounding area, and enables the radio to broadcast to the maximum distance. Note – The radio antenna must have a clear line of sight to the sky at all times during operation. •Choose the most appropriate radio antenna for the size and footprint of the site. The higher the gain on the antenna, the longer the range. If there is more focus on the transmission signal, there is a reduced coverage area. A 3 db or 5 db gain antenna provides a mix of good range and reasonable directional coverage.•Make sure that the GPS receiver does not lose power. The GPS receiver has an integrated battery, which has to be charged. To operate for the full day without loss of power at the base station, provide external power. Sources of external power include:–AC power– 12 V car or truck battery– Trimble custom external battery pack– Generator power–Solar panelWhen you use an external power supply, the integrated battery provides a backup power supply, enabling you to maintain continuous operation through power outages. When the GPS receiver is connected to a power source greater than 15 V, the integrated battery is continuously charged from the connected power source. This helps to ensure that the battery stays charged.•Do not locate a GPS receiver, GPS antenna, or radio antenna within 400 meters (about 1312 feet) of: – a powerful radar, television, or cellular communications tower–another transmitter– another GPS antenna

4 Setup Guidelines34 SPSx50 Modular GPS Receiver User GuideCellular phone towers can interfere with the base station radio broadcast and can stop corrections from reaching the rover receiver. High-power signals from a nearby radio or radar transmitter can overwhelm the receiver circuits. This does not harm the receiver, but can prevent the receiver electronics from functioning correctly.Low-power transmitters, such as those in cellular phones and two-way radios, do not interfere with receiver operations. •Do not set up the base station directly beneath or close to overhead power lines or electrical generation facilities. The electromagnetic fields associated with these utilities can interfere with GPS receiver operation. Other sources of electromagnetic interference include:– Gasoline engines (spark plugs)– Televisions and computer monitors– Alternators and generators– Electric motors–Equipment with DC-to-AC converters– Fluorescent lights–Switching power supplies•Place the GPS receivers in a protected and secure location. If the base station is in the center of a jobsite where heavy machinery is operating, place flags around the base station to warn operators of its existence.•If you place the SPSx50 Modular GPS receiver or SPS770 GPS receiver in a lock box on the jobsite to protect the receiver from theft or from the weather, shield the lock box from direct sunlight and provide ventilation for the receiver through an inlet and extractor fan. A receiver that has a broadcast radio generates significant heat. Do not allow the temperature in the box to exceed 65 ºC (149 ºF). If working in a cold climate, you may need to provide heat to the receiver. Do not operate the receiver below –40 ºC (–40 ºF).•Trimble recommends that, wherever possible, you keep GPS receiver equipment dry. The receivers are designed to withstand wet weather, but keeping them dry prolongs their life and reduces the effects of corrosion on ports and connectors. If the equipment gets wet, dry the equipment with a clean dry cloth, and leave the equipment open to the air to dry. Do not lock wet equipment in a transport case for prolonged periods. Avoid exposing the GPS receiver to corrosive liquids and salt water wherever possible.

SPSx50 Modular GPS Receiver User Guide 35Setup Guidelines 4•Trimble recommends that you install lightning protection equipment at permanent base station locations. Equipment should include a gas capsule lightning protector in the GPS and radio antenna feed line and appropriate safety grounding. A static dissipater near the antennas can reduce the likelihood of a direct lightning strike. Also protect any communications and power lines at building entry points. For more information, contact your local Trimble dealer, or go to the Huber and Suhner website (www.hubersuhnerinc.com).•Trimble recommends that you use surge protection equipment on all permanently installed equipment.Permanent installation antenna cabling for the SPSx50 Modular GPS receiver and SPS770 GPS receiverMany permanent base station installations have unique cabling requirements. Depending on the available infrastructure, you may need to mount the antenna a considerable distance from the receiver.The SPSx50 and SPS770 can withstand a loss of 12 dB between the GPS antenna and the receiver. The degree of loss in a coaxial cable depends on the frequency of the signal passing through it. Table 4.1 lists some common cable types and the maximum length you can use before an inline amplifier for GPS frequencies is required.Rover receiver operation guidelinesThe second part of the RTK GPS system is the rover receiver.The rover receiver is mounted on a pole, vehicle, marine vessel, or in a backpack, and is moved between the points that require measurement or stakeout. The rover receiver is connected to a base station or to a source of RTK corrections such as a Virtual Table 4.1 Maximum cable lenghtsCable type Maximum length (for use without an inline amplifier)RG-214 30 m (100 ft)LMR-400 70 m (230 ft)LMR-500 85 m (280 ft)LMR-600 106 m (350 ft)Heliax LDF4/50 165 m (540 ft)Heliax LDF4.5/40 225 m (740 ft)

4 Setup Guidelines36 SPSx50 Modular GPS Receiver User GuideReference Station (VRS™) system. The connection is provided by an integrated radio, a cellular modem in the controller, or through an external cellular phone that is connected to the receiver either by Bluetooth wireless technogy or by means of a cable.The correction stream for some other positioning solutions, such as SBAS (WAAS/EGNOS, MSAS) and the OmniSTAR XP or HP service1, is broadcast through geostationary satellites, and detected by the GPS antenna itself. No integrated radio or base station is required.Rover receiver componentsThe rover receiver has the following components:•GPS receiver•GPS antenna•Optional integrated radio receiver and antenna for RTK operations•Optional items for the different mounting options (see below)In most rover applications, the receiver operates entirely from its own integrated battery unit. On a vehicle or on a marine vessel, however, an external power supply can be used. Use an external power supply if one is provided. The internal battery then acts as a uninterruptible power supply, covering any power outages.Choose a rover receiver according to the application and the use case:1. A Smart GPS antenna, such as the SPSx80 GPS receiver, incorporates the GPS receiver, GPS antenna, power supply, and receive radio into a single compact unit. A Smart GPS antenna can be rapidly set up on a pole, vehicle, or backpack. This makes it easy to carry when you are measuring around the jobsite. 2. A Modular GPS receiver, such as the SPSx50 GPS receiver, incorporates the GPS receiver, receive radio, and power supply into a single unit. The GPS antenna and, optionally, the receive radio antenna, is separate from the receiver. When you use a modular receiver as a rover, you can use optimized components placed in the best locations for your application. For example:– A small, lightweight rover antenna can be mounted on a pole or backpack; placed in a high, inaccessible location on a marine vessel mast or cabin; or placed on a site vehicle roof or truck bed.– A rubber duck radio antenna, or an external radio antenna, can be mounted on a vehicle or vessel roof to provide maximum coverage.A Modular GPS receiver can be placed in a location that is both easily accessible and safe from theft and the weather. The antennas can be placed high on a vehicle or vessel roof, clear of obstructions and able to deliver maximum performance.1. OmniSTAR is only available with the SPSx50 Modular GPS receiver.

SPSx50 Modular GPS Receiver User Guide 37Setup Guidelines 4Rover receiver setup guidelinesFor good rover operation, observe the following setup guidelines:•Place the GPS antenna in a location that has a clear line of sight to the sky in all directions. Do not place the antenna near vertical obstructions such as buildings, deep cuttings, site vehicles, towers, or tree canopy. GPS rovers and the base station receive the same satellite signals from the same satellites: if you obscure the signals at times, the system will be unable to provide RTK Fixed positions.•Place the GPS and radio antennas as high as possible to minimize multipath from the surrounding area. The receiver must have a clear line of sight to the sky at all times during operation.•GPS satellites are constantly moving. Because you cannot measure at a specific location now does not mean that you will not be able to measure there later, when satellite coverage or location improves. Use GPS planning software to identify the daily best and worst satellite coverage times for your location, and then choose measurement times that coincide with optimal GPS performance. This is especially important when operating in the worst GPS locations.•The SPS850 Extreme and SPS880 Extreme GPS receivers have the ability to track the GPS modernization signals L2C and L5, and the GLONASS satellite constellation. These signals help you to get positions at the worst times of the day and in the worst GPS locations, but do not guarantee that you will.•To get a fixed position solution with centimeter accuracy, initialize the rover receiver. For initialization to take place, the receiver must track at least five satellites that the base station is also tracking.•To maintain a fixed position solution, the rover must continuously track at least four satellites that the base station is also tracking. The radio link between base and rover receivers must also be maintained.•Loss of the satellite signals or loss of the radio link results in a loss of centimeter position accuracy. From Fixed, the receiver changes to Float or Autonomous mode:– In Float mode, the rover has connection to the base station through a radio, but has not yet initialized. – In Autonomous mode, the rover has lost radio contact with the base station receiver, and is working by itself with the available GPS signals.•On a vehicle or marine vessel, place the GPS antenna in a location as free from shock and vibration as possible. For the modular receivers, a single magnetic mount is normally sufficient to hold the antenna in a suitable location, whereas for the larger smart antenna, a triple magnetic mount is normally recommended. Alternatively, a 5/8 thread bolt in a suitable location on the roof bars, or a door mounted pole bracket is a good option.

4 Setup Guidelines38 SPSx50 Modular GPS Receiver User Guide•To mount the modular receiver on a pole use the pole mounting brackets (2) and a second tripod clip (P/N 571 204 300) as shown below.Figure 4.1 Rod mount for modular receiverTo mount the modular receiver on a marine vessel use the receiver bracket (P/N 56830-00). The receiver bracket allows two receivers to be mounted together for marine moving base and heading applications (see chapter XXX Page XXX)•Make sure the rover receiver does not lose power. The rover receivers are typically powered from their internal batteries all day. The batteries in the SPSx80 receiver can be changed when flat. The battery in the SPSx50 receiver cannot be changed, but it last longer than a day (see Chapter 10, Specifications). If you do not use the rover receiver very often, ensure that it is charged at least every three months. For vehicle operation or marine vessel operation, Trimble recommends that you use an external power source so that the internal battery can be saved for times when the receiver is being used off the vehicle or vessel. •Avoid locating the receiver or antenna within 400 meters of powerful radar, television, cellular communications tower, or other transmitters or GPS antennas. Low-power transmitters, such as those in cell phones and two-way radios, normally do not interfere with receiver operations. Cell towers can interfere with the radio and can interfere with GPS signals entering the receiver. High-power signals from a nearby radio or radar transmitter can overwhelm the receiver circuits. This does not harm the receiver, but it can prevent the receiver electronics from functioning correctly.•Do not use the rover receiver directly beneath or close to overhead power lines or electrical generation facilities. The electromagnetic fields associated with these utilities can interfere with GPS receiver operation. Other sources of electromagnetic interference include:– Gasoline engines (spark plugs)– Televisions and computer monitorsRob to provide graphic.

SPSx50 Modular GPS Receiver User Guide 39Setup Guidelines 4– Alternators and generators– Electric motors–Equipment with DC-to-AC converters– Fluorescent lights–Switching power supplies•Trimble recommends that wherever possible all GPS receiver equipment is protected from rain or water ingress. The receivers are designed to withstand all wet weather conditions, however keeping the receivers dry prolongs the life of the equipment and reduces the effects of corrosion on ports and connectors. If the equipment does get wet, dry the equipment with a dry cloth, and leave the equipment open to the air to dry. Do not lock wet equipment in a transport case for prolonged periods. Avoid exposing the GPS receiver to corrosive liquids and salt water wherever possible.•When using the rover receiver in open spaces, Trimble recommends that you stop work during electrical storms where the risk of lightning strike is high.•Where cables are involved, Trimble recommends that you use cable ties to secure the cables to the rod or other equipment to avoid inadvertent snagging while moving about the jobsite. Be careful not to kink, twist, or unnecessarily extend cables, and avoid trapping them in car doors or windows. Damage to cables can reduce the performance of GPS equipment.Internal radio setup for rover operationsThe internal radio of the SPS GPS receiver is delivered with the TX radio frequencies preprogrammed into the receiver. To add more RX radio frequencies, use the WinFlash utility (see Appendix C, Adding Internal Radio Frequencies).Once the radio frequencies are configured, use the SCS900 software to select channel frequencies during base station or rover setup operations.For more information, refer to the the WinFlash Help, or the SCS900 User Guide.External radio setupTo use an external radio with the SPS770 GPS receiver, you need an external power source for the radio.To set up the receiver using an external radio:1. Connect one end of the yellow GPS antenna cable to the yellow TNC port on the receiver.2. Connect the other end of the GPS antenna cable to a Zephyr or Zephyr Geodetic antenna.3. Connect the external radio to Port 3 on the receiver.

4 Setup Guidelines40 SPSx50 Modular GPS Receiver User Guide4. Connect a radio antenna to the external radio as shown in the following figure..Figure 4.2 Connecting an external radio5. Connect an external power source to Port 2 on the receiver.Note – External rover radios must have their own power source because the internal Lithium-Ion batteries do not supply enough voltage. Alternatively, supply external power to port 2 of the receiver, and enable power out on port 3. Base radios must have their own power source because of their high power consumption. Cellular modem and external radioInstead of the internal radio, you can use a cellular modem or an external radio as your data communications link. To connect a cellular modem to an SPSx80 Smart GPS antenna, you need the following:•SPSx80 Smart GPS antenna.•One of the following:– TSC2 controller with CompactFlash card cellular modem, for example, a Audiovox modem card– Cellular modem or a cellphone that can transmit data•Serial (cellphone to DB9) cable (supplied with the cellular modem or phone).•Port 2 of the SPSx80 supports full RS-232 protocol, and should function properly with most cellular phone cables. Some cellular units may require custom cabling.Alternatively, the receiver also supports a cable-free Bluetooth connection with Bluetooth enabled cell phones. For more information on using a cellular modem as a data link, refer to the SCS900 User Guide.23tESC~~()SPS770

The degree of permanence of the setup increases with the expected duration of operational requirements. The more assets that use the base station as a source of corrections, increases the cost of any base station downtime, and increases the requirements for a permanent base station setup. Providing a semi-permanent or permanent setup can also reduce potential sources of error over time caused by repeated daily setup and the potential to put the GPS antenna in the wrong place (that is, not at the original location). On the largest and longest operational jobsites, the permanent or semi-permanent installation is the most common solution. In these cases it is most common to find the SPSx50 Modular GPS receiver or the SPS770 Modular GPS receiver used as the base station. In these installations, the GPS receiver is located typically in a site office or trailer where it is easy to access to check or configure, and where it is secure from theft

5 Setting up the Receiver48 SPSx50 Modular GPS Receiver User Guideand the weather. The GPS and radio antennas are normally mounted on a permanent structure on the roof of the building, where they are high and clear from obstructions and where the radio antenna can provide the maximum range of operation. The GPS antenna used is most commonly the Zephyr Geodetic – Model 2 antenna, which has a large ground plane that eliminates multipath, providing the best GPS performance at the base location. The antennas are connected to the receiver by high quality RF cables.The receiver is connected to a permanent power supply (mains or generator power). The internal battery of the receiver is always being charged, and acts as an uninterruptible power supply if there is a power outage. In some cases, the receiver may also be connected by an Ethernet cable to the Internet, so that it can be monitored and configured from a remote location, and warn an administrator by e-mail or text message if there is a change to the configuration. In these situations, the receiver can transmit GPS RTK corrections to a remote radio or receiver over the Internet for rebroadcast requirements without using repeaters. Figure 5.1 SPSx50 receiver permanent installationSetting up a Base Station for Daily Site Use: T-BarFor construction applications where a daily setup and takedown of equipment is required for security reasons, Trimble recommends that you use a T-Bar setup. The T-Bar consists of a post mounted in concrete (so it cannot move), which has a solid metal Bar T piece mounted to it to provide lateral separation between the GPS antenna and radio antenna. The T piece of the T-Bar will have vertical rods at either end, terminating in a 5/8 thread to which the antennas can be mounted. Trimble

SPSx50 Modular GPS Receiver User Guide 49Setting up the Receiver 5recommends that each end is clearly marked GPS and Radio respectively, to ensure that at each daily setup the GPS and Radio antennas are mounted at the same location. Switching antennas by mistake introduces a position error in all resulting measurements. The equipment required to fabricate a T-Bar can be purchased in any reputable hardware store. Take care to ensure that the T-Bar cannot rotate after construction. Rotation of the T-Bar can introduce a position error into all subsequent measurements.On the upright post, either mount a bracket to which the GPS receiver can be mounted, or place a lock box with ventilation on the post, in which the GPS receiver itself can be secured.Each day, mount the GPS antenna on the GPS end of the T-Bar and the radio antenna on the Radio end of the T-Bar. Connect the Radio and GPS Antenna to the receiver using the appropriate cables. In these scenarios, the receiver will operate from its own integrated battery or from an external 12 V battery through use of the 12 V crocodile clips cable provided with the receiver. If AC power is available, this can be used, however the heat generated by the charging process and the radio transmitter increases the need for good ventilation around the receiver to dissipate the heat.In these scenarios an SPSx80 smart GPS antenna is also often used, in which case the receiver only needs to be mounted on the T-Bar and optionally connected to an external battery or radio unit.The benefit of the T-Bar setup is that it is easy to ensure that the base station is set up daily in the exact same location each day in terms of position and height, that will eliminate the errors typically associated with daily setup on a tripod (wrong antenna heights, not setup over the point, setup in the wrong location etc.)Figure 5.2 System set up on a T-bar

5 Setting up the Receiver50 SPSx50 Modular GPS Receiver User GuideSetting up a Mobile Base Station: Tripod and Fixed Height TripodFor construction applications where you are repeatedly moving between jobsites, or you are visiting a jobsite for the first time before a T-bar or similar setup can be established, Trimble recommends that you use either a tripod and tribrach setup or a fixed height tripod.The fixed height tripod is quicker and easier to setup over a control point. In these situations, you need to take great care to ensure that the GPS antenna is set up accurately over the control point, and that the GPS antenna height is measured accurately, in the right way (vertical or slope height) to the right location on the antenna (base of antenna or to a specified location on the antenna). It is also more important for operators using these types of setup to check in, at one or more known locations, on starting the rover receiver to check for possible position or height errors before starting work. Checking in at a known location is good practice and can avoid costly errors caused by a bad setup.The tripod and fixed height tripod method, typically does not give a significant height clearance above the ground, and can result in reduced range of operation caused by radio limitations.

SPSx50 Modular GPS Receiver User Guide 51Setting up the Receiver 5Tripod SetupIn the tripod setup, the tripod is located over the control point, the tribrach and tribrach adaptor is mounted on the tripod and centered over the point. 1. Mount the GPS antenna on the tribrach adaptor. 2. If you are using a SPSx80 smart GPS antenna, use the 25 cm spacer rod provided with the SPSx80 base station accessory kit to allow the radio antenna in the receiver to clear the head of the tripod. 3. Clip the GPS receiver to the tripod (SPSx50 Modular GPS receiver and SPS770 GPS receiver).4. Connect the GPS antenna using the appropriate cable (SPSx50 Modular GPS receiver and SPS770 GPS receiver). 5. If necessary, connect the GPS receiver to an external 12 V power supply using the crocodile clip cable or the Trimble custom power pack.Figure 5.3 Tripod and tribrach setup for the SPSx50 Modular GPS receiver and SPSx80 Smart GPS antenna

5 Setting up the Receiver52 SPSx50 Modular GPS Receiver User GuideFixed Height Tripod SetupUsing a fixed height tripod, the setup is similar to that of the tripod setup, however the setup is simplified by the central leg of the tripod, that is placed directly on the control point. Provided the central leg is leveled accurately, the fixed height tripod is quick and easy to set up, and provides an easy and accurate means of measuring the true antenna height.1. Set up the tripod over the control point.2. Attach the GPS antenna to the head of the tripod3. When using a high-gain external radio antenna, mount the radio antenna to the radio antenna bracket, which is attached to the head of the tripod beneath the GPS antenna. See Figure 5.4.4. If you are using theSPSx50 Modular GPS receiver, you can hook it to the center leg of the tripod using the tripod clip. 5. If you are using the SPSx80 Smart GPS antenna, you can mount the antenna using the 25 cm spacer rod (supplied with the SPSx80 Base Station Accessory kit) so that the radio antenna clears the head of the tripod.

SPSx50 Modular GPS Receiver User Guide 53Setting up the Receiver 5Common ways to set up a rover receiverThis section describes how to set up a rover receiver in different ways depending on the application. The components that make up a rover receiver are:•GPS receiver•GPS antenna•Controller/Computer•Rod mounting equipment including a rod, receiver bracket, and controller bracket•Vehicle mounting equipment including a suction cup and ball joint, extension arm, controller bracket, magnetic antenna mount, and necessary cables.•Backpack equipment including backpack and antenna-mounting rod•Marine vessel mounting equipment including receiver bracket, cables, antenna, and radio antenna brackets.Setting up the rover receiver on a jobsite vehicleCCAUTION – This solution is suited for off road use while operating a vehicle on a jobsite. This setup is not recommended, or designed, for on road use while driving a vehicle at speed in traffic.To use the receiver as a vehicle-mounted rover receiver, set up the equipment as follows:1. Do one of the following depending on your receiver:– For the SPSx50 or SPS770, mount the GPS antenna for the receiver on the roof of the vehicle, using either a single magnetic mount or a 5/8 thread attached to the roof bars.– For the SPSx80, mount the receiver to the roof of the vehicle using either a triple magnetic mount or a 5/8 thread bolt attached to the roof bars.2. For the SPSx50 or SPS770, run the GPS antenna cable for the receiver into the vehicle either through a rubber grommet in the roof, or through the passenger door window, which needs to be left slightly open during operation.3. For the SPSx50 or SPS770, place and secure the GPS receiver in a convenient location in the vehicle.The GPS receiver can be controlled via the controller connected using Bluetooth wireless technology (cable free) (SPSx50 or SPSx80) or a cable connected to a port on the receiver (SPS770).

5 Setting up the Receiver54 SPSx50 Modular GPS Receiver User GuideThe receiver needs to be accessed only to turn it on at the start of each measurement session. It may be more convenient if the SPSx50 is placed in a location where the vehicle operator can see the keypad and display, to monitor receiver status and to configure settings as required. Most receiver capability can be controlled using the SCS900 controller software.4. Attach the suction cup to either the front windscreen, dashboard, or other convenient location in the vehicle making sure that it does not obstruct the drivers view. 5. Attach the RAM extension arm to the suction cup, and the controller bracket to the RAM extension arm. 6. Lock the controller into the controller bracket, and adjust the bracket until the controller is in the most convenient location. Make sure that the controller does not restrict visibility through the front windscreen during vehicle use.7. Lock the brackets so that the controller is held securely. If required, connect either the GPS receiver or the controller to in vehicle power supplies as needed.Figure 5.5S antenna in a magmount on vehicle roofntroller in suction cup mount in vehicle.b/Nick providing.19 Dec.

When you wear the receiver on a belt, ensure that the display is always visible so that you can easily check the status of the receiver. If you carry the receiver in a backpack, you should use an external radio antenna mount to allow for optimal radio signal reception. If you use a low gain antenna mounted directly on the receiver in a backpack, it may affect the radio signal reception thereby reducing the likelihood of obtaining an RTK Fixed solution.20 Dec. With Vanessa

5 Setting up the Receiver58 SPSx50 Modular GPS Receiver User GuideSetting up a pair of SPSx50 GPS receivers to provide headingThe SPS550H receiver is permanently in Heading mode and, when combined with a suitable Trimble receiver, provides GPS heading. Other SPSx50 GPS receivers can be used for heading only if they can operate in Heading mode (see Configuring the receiver pair, page 64).The SPS550H is a dual-frequency GPS receiver with a dual-frequency antenna, but it does not operate as a stand-alone DGPS receiver. To compute a true north heading and to be capable of positioning, the receiver requires an output message from another SPSx50 receiver. To determine the precise vector between two moving objects, pair the SPS550H heading add-on with any one of the following SPSx50 receivers: •SPS550•SPS750 Max•SPS850Connect the antenna on the SPS550H to the other SPSx50 receiver to determine the precise GPS heading between the two antennas. The SPS550H GPS receiver displays the heading on the two-line display, and outputs the heading data in NMEA or binary format.BTip – To create a single, compact GPS position and heading unit, use the mounting frame provided to stack the SPS550H GPS receiver on top of another SPSx50 GPS receiver. See below. Use the Marine Heading Cable (P/N 57169) provided.The Moving Baseline RTK positioning techniqueIn most RTK applications, the reference receiver remains stationary at a known location and the rover receiver can move. However, Moving Baseline RTK is an RTK positioning technique in which both reference and rover receivers can move about. Moving Baseline RTK is useful for GPS applications that require vessel orientation.Figure 5.9 Vessel heading from Moving Baseline RTK to be doneVessel headingAntennaAntenna

SPSx50 Modular GPS Receiver User Guide 59Setting up the Receiver 5With Moving Baseline RTK, the reference receiver broadcasts Compact Measurement Record (CMR) data every epoch, while the rover receiver performs a synchronized baseline solution at 10 Hz. The resultant baseline solution has centimeter-level accuracy. To increase the accuracy of the absolute location of the two antennas, the Moving Reference receiver can use differential corrections from a static source, such as a shore-based reference station.Mounting a pair of SPSx50 GPS receiversTo obtain a position and heading solution, you need to connect two SPSx50 receivers to make one compact unit. A mounting bracket and interconnecting cable is supplied with the SPS550H receiver. Set up the receivers, antennas, and cables as shown in Figure 5.2.

Secure all eight bolts in this way..16. Attach one connector from the Marine Heading Cable (P/N 57169) to the 26-pin connector on the rear of the SPS550H GPS receiver. Attach the other connector from the cable to the 26-pin connector on the rear of the SPSx50 receiver. The cable can be connected either way around. The cable connects the two GPS receivers so that the Heading solution is available. The DC power lead on the cable is used to supply power to both receivers in the stack. The two DB9 female connectors on the cable access serial port 2 on each receiver.Installing the receiverSelect a location at which all of the following conditions are met:•the receiver is not exposed to temperature extremes

5 Setting up the Receiver64 SPSx50 Modular GPS Receiver User Guide•the receiver is not exposed to moisture extremes (such as rain, snow, water blasters, or wash systems)•the receiver is protected from mechanical damage•you can connect and disconnect cables without placing undue stress on themMounting the antennasIt is critical that you install each antenna at the correct location. Poor or incorrect placement can influence accuracy and reliability.Ideally, mount the two antennas as far apart as possible and at about the same height on the structure. Mount the antennas fore and aft along the vessel centerline or on a line that is at a known orientation to the centerline. Always mount an antenna at a location that ensures a good view of the sky. Follow these guidelines to select the antenna location:•Choose an area with a clear view of the sky. The antenna must be above any metallic objects.•Do not mount the antenna close to stays, electrical cables, metal masts, or other antennas.•Do not mount the antenna near a transmitting antenna, a radar array, or near satellite communication equipment.•Avoid areas with high vibration, excessive heat, electrical interference, and strong magnetic fields.Use a 5/8" stainless steel bolt to mount each of the antennas. There is a threaded bolt hole in the base of the antenna.Configuring the receiver pairOne of the receivers must be nominated as a Heading unit. The other receiver is nominated as a Moving Base unit. For this configuration to work, you must use the Marine heading cable (P/N 57169). To set up the Heading unit:1. From the Home screen press <enter><enter>. The Mode screen appears. 2. Select Heading mode. The SPSx50 display shows two extra settings for heading: –Heading Adjustment. Enter a positive value in decimal degrees. The value is applied to the raw heading value before it is output in the NMEA HDT message or displayed on the front panel of the receiver. This value is used when the two antennas are not mounted parallel to the vessel axis.

SPSx50 Modular GPS Receiver User Guide 65Setting up the Receiver 5–Minimum Heading Solution. Enter the minimum requirement for the GPS solution that will provide the heading value. The default of RTK Fixed provides the highest precision, but in conditions of extreme multipath or obstruction, an RTK Fixed solution may not be continuously available. In such conditions, select RTK Float if a lower precision is acceptable. To set up the Moving Base unit:1. From the Home screen press <enter><enter>. The Mode screen appears. 2. Select Moving Base mode.Interfacing using the NMEA protocolThe SPS550H GPS receiver can output messages such as NMEA HDT for heading, and NMEA GGA for position. The SPS550H always reports the solution status of the moving baseline solution that is being used to compute the heading. For example, Modem (serial port 2) on SPS750, which is typically RTK Fixed Integer. However, if the external computer must know the exact quality of the position, you can use the NMEA output from the base receiver. The base receiver reports the solution status of the position, for example, Fixed Integer, Floating, orDGPS.

This appendix describes the different configuration methods, and explains when and why each method is used.The SCS900 Site Controller software is likely to be your main tool to set up and operate the receiver on a daily basis. For more information, refer to the Trimble SCS900 Site Controller Software Getting Started Guide or the Trimble SCS900 Site Controller Software Office Guide.The external software detailed in this appendix is primarily used to update the receiver firmware and to configure upgrades or radio channels. All necessary field configurations are handled through the SCS900 software running on a TSC2™ or TCU controller.

7 Configuring the Receiver Settings76 SPSx50 Modular GPS Receiver User GuideUsing the SCS900 Site Controller software to configure the base station, rover, and the radios As a total system solution for construction applications, the SPS GPS receivers are operated by a TSCe™, ACU, TCU, or TSC2 controller running the SCS900 Site Controller software. The SCS900 system provides the tools to configure and start the GPS receiver in the modes used by the SCS900 system: Base Station, RTK Rover, Location RTK Rover, OmniSTAR Rover, and DGPS Rover using SBAS (WAAS/EGNOS and MSAS). The SCS900 software provide wizards to help you through the process and, where possible, assigns suitable default operational parameters to the system. This eliminates the need for an operator to know how to configure the receiver with the right settings.The SCS900 system takes care of operating the receiver with both internal and external radios, cellular communications components (modems and cellphones), and use of the Bluetooth wireless technology. The software also takes care of scanning communication ports to identify connected devices, and offers selection options wherever necessary often with pictures to facilitate the correct component selection at times when it cannot automatically identify the connected component, for example, GPS antennas.The SCS900 system allows you to specify operational tolerances, which have to be achieved for measurements to be accepted. When outside of these tolerances, the SCS900 system warns you through on-screen messages or indications, and the non automatic acceptance of recorded positions. To set operational tolerances, go to the the Settings menu in the SCS900 software.Configuring the receiver to log data for postprocessing The SPS GPS receivers do not come equipped with the Data Logging option. The receivers can have this added either at the time of purchase, or at a later date as an option. With the Data Logging option enabled, the receiver has available memory, that facilitates the collection of GPS observations over a period of time, which can be used with GPS postprocessing software such as Trimble Geomatics Office or Trimble Total Control, for the computation of control networks and baselines.The SCS900 Sky Plot screenPress Ctrl+M to open this screen

SPSx50 Modular GPS Receiver User Guide 77Configuring the Receiver Settings 7The SCS900 system does not provide support for postprocessed applications. Trimble recommends that you use either the front panel keypad and display, the Web User Interface, or (SPS770, SPSx80 only) the GPS Configurator software to configure the receiver for postprocessed measurement sessions. Configuring Ethernet SettingsThe SPSx50 receiver has an Ethernet port so that the receiver can connect to an Ethernet network. The receiver can be accessed across the network giving you the ability to configure and monitor the receiver without needing to connect to the receiver with a serial cable.The SPSx50 receiver requires the following Ethernet settings:•IP setup: Static or DHCP•IP address•Netmask•Broadcast•Gateway•DNS address•HTTP portThe factory default configuration of the SPSx50 receiver is to use DHCP. Using DHCP enables the receiver to obtain the IP address, Netmask, Broadcast, Gateway, and DNS address from the network. The default setting for the HTTP port is 80. The HTTP port is not assigned by the network. HTTP port 80 is the standard port for web servers. This allows you to connect to the receiver by entering only the IP address of the receiver in a web browser. If the SPSx50 receiver is set up to use a port other than 80, you will need to enter the IP address followed by the port number in a web browser. Example of connecting to the receiver using port 80: http://169.254.1.0Example of connecting to the receiver using port 4000: http://169.254.1.0:4000When an SPSx50 receiver is connected to a network using DHCP, an IP address is assigned to the receiver by the network. To verify the IP address of the receiver, select the up button from the keypad when the Home screen is displayed. The display will show the Ethernet IP address as shown.If your network installation requires the receiver to be configured with a static IP address, you can configure the Ethernet settings using the web server or the WinFlash software. The web server can be only used when the receiver is connected to a network and has a valid Ethernet configuration.

7 Configuring the Receiver Settings78 SPSx50 Modular GPS Receiver User GuideYou should use the WinFlash software to configure the Ethernet settings of a receiver that is to be connected to a network that requires static IP addresses. If a network requires static IP addresses, contact the network administrator for the correct settings for the SPSx50 receiver.To configure the Ethernet settings using the WinFlash software:1. Connect the SPSx50 receiver to a computer running the WinFlash software using the serial cable provided with the receiver.2. Turn on the SPSx50 receiver.3. On the computer, start the WinFlash software.4. From the Device screen, select Trimble SPSx50 Receiver, and then from the PC serial port list, select the appropriate PC serial port. Click Next:

Enter the network settings (obtain these from your network administrator), and then click OK:The Broadcast setting is the IP address that is used to broadcast to all devices on the subnet. This is usually the highest address in the subnet, which is usually .255.
