IntroductionHiPer XT Operator’s Manual1-2OverviewTopcon Positioning System’s HiPer XT is a dual-frequency, GPS+ receiver built to be the most advanced and compact receiver for the surveying market. The HiPer XT is a multi-function, multi-purpose receiver intended for precision markets. Precision markets means markets for equipment, subsystems, components and software for surveying, construction, commercial mapping, civil engineering, precision agriculture and land-based construction and agriculture machine control, photogrammetry mapping, hydrographic and any use reasonably related to the foregoing.The HiPer XT can receive and process both L1 and L2 signals, improving the accuracy of your survey points and positions. The dual-frequency and GPS+ features of HiPer XT combine to provide a real time kinematic (RTK) system accurate for short and long baselines. Several other features, including multipath mitigation and co-op tracking, provide under-canopy and low signal strength reception. The receiver provides the functionality, accuracy, availability, and integrity needed for fast and easy data collection.Principles of OperationSurveying with the right GPS receiver can provide users accurate and precise positioning, a requirement for any surveying project.This section gives an overview of GPS and receiver functions to help you understand and apply GPS principles, allowing you to get the most out of your receiver.GPS OverviewThe Global Positioning System (GPS) is a satellite-based, line-of-sight radio navigation system run by the United States Department of Defense (DoD). This system offers a global, all weather, 24-hour positioning, velocity, and time service to any user equipped with a GPS tracking receiver, who is on or near the Earth’s surface. The Global Navigation Satellite System (GLONASS), is the Russian Federation Ministry of Defense counterpart to GPS.
Principles of OperationP/N 7010-0713 1-3For information on the current status of the GPS constellation, visit http://tycho.usno.navy.mil/ or http://www.navcen.uscg.gov/. For GLONASS, visit http://www.glonass-center.ru/frame.html.Despite numerous technical differences in the implementation of these systems, both GPS and GLONASS have three essential components:• Space – GPS and GLONASS satellites orbiting approximately 12,000 nautical miles above Earth and are equipped with a clock and radio. These satellites broadcast digital information (ephemerides, almanacs, time&frequency corrections, etc.).• Control – Ground stations located around the Earth that monitor the satellites and upload data, including clock corrections and new ephemerides (satellite positions as a function of time), to ensure the satellites transmit data properly.• User – The community and military that use GPS/GLONASS receivers and the corresponding satellites to calculate positions.Calculating PositionsOnce the receiver locks on to a satellite, it starts recording measurements and receiving the various digital information (ephemerides, almanac, and so on) the satellites broadcast. To calculate a position, receivers use the following formula:Velocity x Time = DistanceWhere Velocity is the speed at which radio waves travel (i.e., the speed of light) and Time is the difference between the signal transmission time and signal reception time.To calculate absolute 3-D positions—latitude, longitude, altitude—the receiver must lock on to four satellites. In a mixed, GPS and GLONASS scenario, receiver’s must lock onto at least five satellites to obtain an absolute position. To provide fault tolerance using only GPS or only GLONASS, the receiver must lock onto a fifth satellite. Six satellites will provide fault tolerance in mixed scenarios.
IntroductionHiPer XT Operator’s Manual1-4Once locked on to a satellite, the receiver collects ephemerides and almanacs, saving this information to its NVRAM (Non-Volatile RAM).• GPS and GLONASS satellites broadcast ephemeris data cyclically, with a period of 30 seconds. • GPS satellites broadcast almanac data cyclically with a period of 12.5 minutes; GLONASS satellites broadcast almanac data cyclically with a period of 2.5 minutes.GPS PositioningAchieving quality position results requires the following elements:• Accuracy – The accuracy of a position primarily depends upon the satellite geometry (Geometric Dilution of Precision, or GDOP) and the measurement (ranging) errors.– Differential positioning (DGPS and RTK) strongly mitigates atmospheric and orbital errors, and counteracts anti-spoofing signals the US Department of Defense transmits with GPS signals.– The more satellites in view, the stronger the signal, the lower the DOP number, the higher positioning accuracy.• Availability – The availability of satellites affects the calculation of valid positions. The more visible satellites available, the more valid and accurate the position. Natural and man-made objects can block, interrupt, and distort signals, lowering the number of available satellites and adversely affecting signal reception.• Integrity – Fault tolerance allows a position to have greater integrity, increasing accuracy. Several factors combine to provide fault tolerance, including:– Receiver Autonomous Integrity Monitoring (RAIM) detects faulty GPS and GLONASS satellites and removes them from the position calculation.– Five or more visible satellites for only GPS or only GLONASS; six or more satellites for mixed scenarios.
Principles of OperationP/N 7010-0713 1-5– Wide Area Augmentation Systems (WAAS, EGNOS, etc.) creates and transmit, along with DGPS corrections, data integrity information (for example, satellite health warnings).– Current ephemerides and almanacs.ConclusionThis overview simply outlines the basics of GPS and GLONASS positioning. For more detailed information, visit the TPS website (www.topconps.com/gpstutorial/).Receiver OverviewWhen power is turned on and the receiver self-test completes, the receiver’s 20 channels initialize and begin tracking visible GPS satellites. Each of the receiver’s channels can be used to track C/A-L1, P-L1, or P-L2 signals. The number of channels available allows the receiver to track all visible GPS satellites at any time and location.An internal GPS antenna equipped with a low noise amplifier (LNA) and the receiver’s radio frequency (RF) device are connected with a coaxial cable. The wide-band signal received is down-converted, filtered, digitized, and assigned to different channels. The receiver processor controls the process of signal tracking.Once the signal is locked in the channel, it is demodulated and necessary signal parameters (carrier and code phases) are measured. Also, broadcast navigation data are retrieved from the navigation frame.After the receiver locks on to four or more satellites, it is possible to solve the so-called “absolute positioning problem” and compute the receiver’s coordinates (in WGS-84) and the time offset between the receiver clock and GPS time. All this information is stored in the receiver’s memory, which can be downloaded later onto a computer and processed using a post-processing software package. When the receiver is run in RTK mode, raw data measurements can also be recorded into the receiver’s internal memory. This allows the operator to double check real-time results obtained in the field.

IntroductionHiPer XT Operator’s Manual1-10Getting AcquaintedThe HiPer XT receiver is 158.5mm wide, 173mm deep, 113mm high, and weighs approximately ??kg. The receiver’s advanced design allows users to significantly reduce the number of cables required for receiver operation, with the ability to perform jobs more reliably and efficiently, especially when moving.The receiver is also versatile and can be configured in several different ways. The casing allocates space for two nonremovable, on-board Li-Ion batteries, a Bluetooth wireless technology module, a GSM communication module (optional), and two Euro cards. One of the Euro cards is the GPS receiver and the other is used for UHF communications.See Table 1-2 on page 1-13 for a description of the operating times for the HiPer XT receiver as a Base or Rover. For receiver specifications, see Appendix A.Internal ComponentsThe following sections describe the internal components of the HiPer XT receiver.GPS+ AntennaAn internal, micro-strip antenna capable of receiving GPS L1/L2 signals and GLONASS L1/L2 signals.Bluetooth ModuleA combination of software and hardware technology that makes the HiPer XT a mobile, wireless, GPS+ receiver that support a point-to-point serial profile. As such, the HiPer XT can transfer and synchronize files between the receiver and any other Bluetooth wireless technology device that supports serial profile, including portable handheld devices and external controllers, Bluetooth adapters for PC-USB/RS ports, mobile computers and phones, IPAQs, PCMCA-to-Bluetooth adapters, etc.
Getting AcquaintedP/N 7010-0713 1-11With Bluetooth wireless technology, the receiver’s reception and transmission distance is 10 meters (32 feet) for interior projects and 30–50 meters (98–164 feet) for exterior projects.The Bluetooth module’s processor and firmware are independent of the receiver card and power board. Radio ModemThe receiver incorporates an internal, TPS UHF transmitter/receiver at 20MHz bandwidth, with a 12.5/25kHz channel spacing, and a maximum 2W power output for data transmission. The Base station’s modem transmits the carrier phase and code measurements along with the reference station information (that is, location) to the Rover station modem.The frequency range of the modem depends on the country in which the receiver is used: for North America, the frequency range is 410–470; for all other countries, contact your local distributor.TIP TIPThe HiPer XT is compatible with Pacific Crest radio modems.GSM ModuleGSM modems function similarly to a standard cell phone, where one modem (at the Rover) calls another (at the Base). If your receivers are configured with GSM capabilities, a phone number and service plan are required. Contact your Topcon dealer for details.ANYTHING ELSE??The GSM module internally connects to and controls through the UHF modem board.Power BoardThe internal power board manages receiver power and battery charging, and is connected to the receiver board and the batteries. The power board receives power from the internal batteries, even when the
IntroductionHiPer XT Operator’s Manual1-12receiver is turned off. This feature allows the internal batteries to charge, regardless of the receiver’s status (on or off). To prevent the batteries from discharging when the receiver is stored, put the receiver in Zero Power Mode (see “Zero Power Mode” on page 4-19 for more information). The batteries will not charge in this mode.The power board’s processor and firmware are independent of the receiver card. To ensure firmware compatibility, the GPS receiver board and power board must be loaded with firmware from the same package.GPS+ Receiver BoardThe receiver is supplied with a Euro-112T card capable of processing the following signals:• GPS L1 or GPS L1/L2• GPS/GLONASS L1 or GPS/GLONASS L1/L2Table 1-1 lists the options available for these cards. A WAAS-enabled TPS receiver allows simultaneous tracking of two WAAS satellites. Each of the WAAS satellites is allocated its own channel.BatteryThe receiver is equipped with two non-removable, on-board, rechargeable Lithium-Ion battery packs connected to the receiver’s power board. Each one of these Lithium-Ion battery packs is 7.4 V and 4 Ah, giving you a total power of 7.4 V, nominal, and 8 Ah when fully charged.Table 1-1.

Typically, all receivers ship with a temporary OAF that allows it to be used for a predetermined period of time. When the receiver is purchased, a new OAF permanently activates desired, purchased options. Receiver options remain intact when clearing the NVRAM or resetting the receiver.The OAF enables the following kinds of functions. For a complete list of available options and details, visit the TPS website (www.topcongps.com/tech/index) or consult your TPS dealer.• Type of signal (standard L1; optional L2)• Memory (standard 0MB; optional 1MB to 128MB)Slant Height Measure MarkVent Plug

Powering the ReceiverP/N 7010-0713 2-3The speed of the charge depends on the Power and Charger settings on the Receiver Configuration screen, and whether the receiver is turned off or on. See “Power Management” on page 2-5 for more information.The Li-Ion batteries used in the receiver should run at no less than 98% capacity after 500 charging cycles. These batteries do not need to be drained before recharging.External BatteriesIn addition to the internal batteries, you can use your receiver with external batteries (Figure 2-1 on page 2-4). External batteries allows you to continue using the receiver in case the internal batteries are discharged and requires the following:• a 12 V, 2.3 A*h battery• a 2.3 A*h battery clip-to-SAE cable• an SAE-to-Power Plug cableNOTICENOTICEWhen the receiver uses external batteries, set the charger mode to Off. Otherwise, the external batteries will also charge the internal batteries, causing operation time to decrease. See “Power Management” on page 2-5 for more information on setting the charger mode.1. Connect the SAE ends of the battery clip-to-SAE and the SAE-to-power plug cables.2. Plug the power cable into the receiver’s power port.3. Attach the battery clip to the battery.
ConfigurationHiPer XT Operator’s Manual2-4A single external 12 V, 2.3 A*h battery should run the receiver for about 7 hours and the receiver and modem for 5 hours. Figure 2-1. External Battery Attached to ReceiverTIP TIPYou can also use an SAE-to-SAE extension cable and an Alligator clip-to-SAE cable, and power the receiver from a battery, such as the battery used to power your Base radio or similar battery.Battery ChargerThe same charger used to charge the internal batteries can be used as an external power supply for the receiver. The charger is provided with the receiver package.1. Connect the receiver-to-SAE cable to the receiver’s power port.2. Connect the SAE end of the cable to the battery charger.3. Plug the battery charger’s power cable into the AC adapter.4. Plug the power cable into an available, grounded outlet. The power input for your battery charger should be AC between 90 and 264 V 1A (110 V AC) and between 47 Hz and 63 Hz. The battery charger outputs DC 12 V 2.5 A (30 W).

Receiver Configuration – MINTER TabRecording Interval parameterThis parameter specifies the message output interval into the log file when the MINTER FN key (pressed for 1–5 seconds) activates data logging. This setting is used for both logging a single log file, and logging receiver data in AFRM mode. Values are 1–86400 seconds.The default value is one second.Elevation Mask for Log File parameterThis parameter specifies the minimum elevation angle for the satellites whose data will be put in the receiver files logged when pressing FN.The default value is five degrees.
MINTER ConfigurationP/N 7010-0713 2-21File Name Prefix parameterThis parameter specifies the prefix added to the names of receiver files created when pressing FN. The prefix can be up to 20 characters long. The default value for the Name Prefix is “log”. Log file names have the following structure:<prefix><month><day><sequential alphabet letter>The file name depends on both the file creation time (month and day) and additional letter suffixes to avoid confusion between files created on the same day. Always Append to the File parameterIf you want new receiver data to be appended to an existing log file, enter the desired file name in this parameter. The setting can be up to 20 characters long.Files Creation Mode parameterThis parameter has two possible operation modes:• Log file – If the log file radio button has been selected, pressing the FN key closes the current log file. If data logging is off, pressing FN opens a new log file.• AFRM – If AFRM radio button has been selected, pressing FN enables this mode. If AFRM has been enabled, pressing FN disables this mode.Automatic File Rotation Mode (AFRM) parametersTPS receivers are capable of automatically rotating log files. During a “file rotation” event, the receiver closes the current file and opens a new one according to a user-defined schedule. The Period and Phase parameters specify this schedule. File rotation launches the moment the receiver time module Period is equal to Phase. More precisely, a new log file opens immediately before the scheduled epoch causing data tagged with this epoch to be recorded to the new log file.When opening a new log file, the receiver enables the default set of messages outputted with the default output period. Both the
ConfigurationHiPer XT Operator’s Manual2-22default set of messages and the default output period are programmable.• Period – specifies the time duration of each log file created in AFRM mode. Values are 60 to 86400 seconds; default value is 3600 seconds.• Phase – specifies the “phase” (constant time shift) of creating multiple log files in AFRM mode. Values are 0 to 86400 seconds; default value is zero seconds.• Files (total) – a counter that specifies how many multiple log files must be created in AFRM until this mode automatically turns off. This counter decrements on every file rotation until it value becomes zero, then file rotation automatically stops. The counter initializes with AFRM.Note that a log file opens immediately after turning AFRM on. This startup file is not considered a file rotation event; the AFRM counter will not decrement.Values are 0 to [231-1]; default value is 0 (zero). Zero means that an unlimited number of log files will be created.NOTICENOTICEThe receiver’s memory holds up to 512 files.• Files (remain) – specifies the number of files left for the receiver to create in AFRM.Values are 0 to [231-1]; default value is zero.• Automatically remove old files – when no free memory is available to log data, automatically removes the earliest log file. If this parameter is enabled, your receiver will erase the file with the earliest file creation time/date. AFRM must be enabled to use this FIFO (First-In, First-Out) feature.The default value is off (disabled).
MINTER ConfigurationP/N 7010-0713 2-23FN Key Mode parameterUse these two radio buttons to program how the receiver will react when pressing the FN key.• LED blink mode switch – pressing FN will toggle between the MINTER’s normal/extended information modes and start/stop data recording of Static survey.–FN pressed for less than 1 second: changes the information mode (Normal or Extended Information (EI) Modes).–FN pressed for 1 to 5 seconds: starts or stops data recording (Static post-processing mode).• Occupation mode switch – pressing FN (less than one second) will insert into the corresponding log file a message indicating that the survey type has been changed from static to kinematic, or vice versa. If the REC LED blinks green, the current mode is dynamic, if it blinks orange, the current mode is static. For more details, see Table 4-1 on page 4-5 and refer to the MINTER User’s Manual and PC-CDU User’s Manual.Initial Data Collection Dynamic Mode parameterThese radio buttons specify the starting occupation type descriptor inserted at the beginning of receiver files logged. Select Static or Kinematic to specify that the corresponding log file will start with a static (STOP) or kinematic (GO, Trajectory) occupation, respectively.Data Recording Auto-start parameterThese radio buttons allow you to program your receiver’s behavior in the event of a power failure. Table 2-2 on page 2-24 gives the different scenarios available and the results after power is restored to the receiver. “Specified file” refers to the file name entered in the Always append to file parameter.
ConfigurationHiPer XT Operator’s Manual2-24Also, if Always is enabled, your receiver will automatically start logging data (to a newly created or an existing file) in the following three cases:• After turning on the receiver using the Power key.• After resetting the receiver (using PC-CDU or pressing the Reset key).• After taking the receiver out of Sleep Mode.Table 2-2.

To configure the UHF radio modems, have the following ready:• Computer running Windows® 98 or newer• Modem-TPS ver 1.7 or newer• Serial cable (or Bluetooth wireless technology capabilities)1. Connect the computer and receiver using an RS232 cable or Bluetooth wireless technology.2. Turn on the receiver.3. Open Modem-TPS and select the COM port the receiver is connected to (Figure 2-19).4. Click Connect.Figure 2-19. Connect to Modem-TPS
ConfigurationHiPer XT Operator’s Manual2-28When finished configuring the radio modem, always disconnect from Modem-TPS before exiting to prevent conflicts with serial port management.There are two scenarios for configuring the radio-modem:• with a dedicated channel• with the FCS modeSet Radio Link Parameters for a Dedicated Channel1. From the Protocol control, select between TPS and PDL.• TPS – Select this protocol if all of the radio-modems at your jobsite are manufactured by Topcon Positioning Systems.• PDL – Select this protocol if you use PDL radio-modem(s) together with TPS radio-modem(s) at the jobsite.2. From the Modulation Type control, select a modulation scheme that will be used by your base radio-modem. It can be either 4-Level-FSK (Frequency Shift Keying) or GMSK (Gaussian Minimum Shift Keying). The following table shows you what modulation technique can be used at a specific link rate.3. From the Link Rate control, select the rate at which data is transmitted over the RF link. The UHF radio-modem supports 4800, 9600, and 19200 baud. Note that this setting affects the Modulation Type control and vice versa.4.

Radio ConfigurationP/N 7010-0713 2-296. For a maximum data communication reliability, select the Forward Error Correction checkbox. With this parameter enabled, the rover radio-modem has the capability to check and correct transmission errors (if any) in an incoming data stream.NOTICENOTICEWhile providing error control in data transmission, FEC adds redundant check bits to the data stream reducing data throughput. If you are going to use FEC and a format of differential messages requires a great deal of data (e.g., RTCM 2.x) transmitted over the radio link, it is recommended to select 19200@4-Level-FSK. This will ensure reliable radio communication between the base and rover receivers.7. From the Protocol Mode control, select the appropriate link protocol among the following available:• Transparent w/EOT Character• Transparent w/EOT Timeout•Fast Async8. If you select Transparent w/EOT Character, the EOT Character (Dec) field will be displayed. In this field enter a decimal value (usually a control character). Once the specified character is found in the incoming data stream, the modem begins data transmission.If you select Transparent w/EOT Timeout, the TX ACK Timeout (in x10 ms) field will be displayed. In this field enter an integer value between 1 (corresponds to 10 ms) and 50 (corresponds to 500 ms). Once the timeout between incoming data exceeds the specified value, the modem begins data transmission.

Only one radio may be used at a time.To set up the receivers, you must:1. Configure the receivers as shown in Chapter 2.2. Set up the Base and Rover stations. See “Step 1: Set up the Receiver” on page 3-2.3. Measure the antenna height. See “Step 2: Measure Antenna Height” on page 3-2 for internal antennas.4. Begin collecting data. See “Step 3: Collect Data” on page 3-4.All receivers include an internal, micro-strip antenna able to capture L1/L2 signals from GPS and GLONASS satellites.
Setup and SurveyHiPer XT Operator’s Manual3-2Step 1: Set up the ReceiverThis section assumes the receiver has already been configured.1. Place the receiver on the appropriate tripod or bipod.2. Center the receiver over the point at which data will be collected. For most applications, this should be at a location with a clear view of the sky.Step 2: Measure Antenna HeightThe location of the antenna relative to the point being measured is very important for both surveys in which the elevation of the points is important and in surveys for horizontal location only. Horizontal surveys are often larger in area than can reliably fit on a flat plane, therefore the antenna adjustment must be done in three dimensions and then projected onto a two dimensional plane.The receiver calculates the coordinates of the antenna’s phase center. To determine the coordinates of the station marker, the user must specify the following:• Measured height of the antenna above the station marker• Method of measuring the antenna height• Model of the antenna usedAntennas have two types of measurements:• Vertical – measured from the marker to the antenna reference point (ARP) located on the bottom of the receiver at the base of the mounting threads. • Slant – measured from the marker to the lower edge of the antenna slant height measure mark (SHMM) located on both end panels of the receiver.1. Measure the antenna height above the point or marker.Figure 3-1 illustrates the antenna offsets. (See Figure 1-5 on page 1-15 and Figure 1-6 on page 1-16 for the exact SHMM location.)
Receiver SetupP/N 7010-0713 3-3Figure 3-1. HiPer XT Antenna Offsets• SHMM to ARP vertical offset = 30.50mm• SHMM to ARP horizontal offset = 77.75mmTable 3-1gives the offset values for the receivers.The point to which surveying with GPS/GLONASS measures is called the Phase Center of the antenna. This is analogous to the point at which a distance meter measures in a prism. A user must enter the prism offset to compensate for this point not being at a physical surface of the prism. In the case of a GPS/GLONASS antenna, the offset is entered depending on the type of measurement taken. For vertical, the offset is simply added to the measured vertical height to produce a “true” vertical height. For slant height, the vertical height must first be calculated using the radius of the antenna, then the offset can be added. The offsets are not the same number because of the difference in location between the slant measuring point and the vertical measuring point.2. Record the antenna height, point name, and start time in the field notes. Table 3-1.

Setup and SurveyHiPer XT Operator’s Manual3-43. Press the power key and release it to turn the receiver on. The STAT (status) light (LED) will blink red at first. 4. Once the receiver has locked on to one or more satellites, the STAT light will blink green for GPS satellites, orange for GLONASS satellites, and a short red blink indicating it has not solved a position. Four or more satellites provide optimal positioning.5. Once the short red blink is gone, the receiver has a position and surveying can begin. You should wait for green and orange lights before beginning data collection. This ensures that the receiver has the correct date and time, and is locked on to enough satellites to ensure good quality data.The process of locking on to satellites normally takes less than one minute. In a new area, under heavy tree canopy, or after resetting the receiver, it may take several minutes.Step 3: Collect Data1. To begin collecting data, press and hold the FN (function) key for more than one second and less than five seconds.2. Release the FN key when the REC (recording) LED light turns green. This indicates that a file has opened and data collection has started. The REC LED blinks each time data is saved to the internal memory.TIP TIPUse PC-CDU to configure data logging. See “MINTER Configuration” on page 2-18 or refer to the PC-CDU User’s Manual.3. When finished, press and hold the FN key until the REC LED light goes out. 4. To turn off the receiver, press and hold the power key until all lights go out, then release.
Surveying with the ReceiverP/N 7010-0713 3-5Surveying with the ReceiverThe receiver can be used to perform Static, Kinemati, and Real-time kinematic (RTK) surveying.NOTICENOTICETo comply with RF exposure requirements, maintain at least 25cm between the user and the radio modem.Static SurveyStatic surveying is the classic survey method, well suited for all kinds of baselines (short, medium, long). At least two receiver antennas, plumbed over survey marks, simultaneously collect raw data at each end of a baseline during a certain period of time. These two receivers track four or more common satellites, have a common data logging rate (5–30 seconds), and the same elevation mask angles. The length of the observation sessions can vary from a few minutes to several hours. The optimal observation session length depends on the surveyor’s experience as well as the following factors:• The length of the baseline measured• The number of satellites in view• The satellite geometry (DOP)• The antenna’s location• The ionospheric activity level• The types of receivers used• The accuracy requirements• The necessity of resolving carrier phase ambiguitiesGenerally, single-frequency receivers are used for baselines whose lengths do not exceed 15 kilometers (9.32 miles). For baselines of 15 kilometers or greater, use dual-frequency receivers.Dual-frequency receivers have two major benefits. First, dual-frequency receivers can estimate and remove almost all ionospheric effect from the code and carrier phase measurements, providing much
Setup and SurveyHiPer XT Operator’s Manual3-6greater accuracy than single-frequency receivers over long baselines or during ionospheric storms. Secondly, dual-frequency receivers need far less observation time to reach the desired accuracy requirement.After the survey completes, data the receivers collect can be downloaded onto a computer and processed using post-processing software (for example, Topcon Tools). The procedure that follows describes the steps the operator should take to perform a Static Survey using MINTER.1. Connect your receiver and computer.

Setup and SurveyHiPer XT Operator’s Manual3-8Kinematic (Stop and Go) SurveyIn a kinematic, stop and go survey, the stationary receiver (Base station) is set up at a known point such as a survey monument, or an unknown point. The receiver continually tracks satellites and logs raw data into its memory. The rover receiver is set up at an unknown point and collects data in static mode for 2 to 10 minutes. When finished, assign the Rover to kinematic status and move to the next survey point. At this point, and each subsequent point, the receiver is changed to static mode to collect data. So, while moving, the Rover is in kinematic mode, and while collecting data, the Rover is in static mode.1. Using PC-CDU, configure and set up the Base as described in “Static Survey” on page 3-5.2.

Check the STAT light for satellites tracked.5. When finished, press the FN key for less than a second to assign the Rover to kinematic. TIP TIPRemember, if the REC LED blinks green, the current mode is dynamic, if it blinks orange, the current mode is static.6. Move the Rover to the next location (survey point), and press the FN key for less than a second to collect the data in static mode for two to ten minutes.7. Repeat steps five and six until all points have been surveyed. The occupation time for the points depends on the same factors as for the static survey method.8. When finished, press the FN key for one to five seconds to stop logging data. Turn off the Rover if needed.This method of GPS survey allows the operator to reduce the point occupation time, thus permitting field crews to survey many more points compared to the other methods available.Real-time Kinematic SurveyReal-time kinematic (RTK) is a differential GPS process where information, such as differential corrections, is transmitted in real-time from a Base station to one or more Rover stations.Set up an RTK Base StationTo configure an RTK Base station using PC-CDU, take the following steps:1.

The receiver begins sending data to the selected port.For more details on the settings available for configuring the Base station, refer to the PC-CDU User’s Manual.
Surveying with the ReceiverP/N 7010-0713 3-13Set up an RTK RoverUse the following steps to set up an RTK Rover station. You should already have programmed the modem.Figure 3-10 shows the hardware setup for a Rover station with an external controller.Figure 3-10. Rover Station Setup1. Set up the Rover station receiver’s antenna as described in “Receiver Setup” on page 3-1.2. Connect the receiver and computer. See “Connecting the Receiver and a Computer” on page 2-10.3. Click ConfigurationReceiver.4. Click the Positioning tab and set the Position Masks,Elevation mask (degrees) parameter to 15 (Figure 3-7 on page 3-10).
Setup and SurveyHiPer XT Operator’s Manual3-145. Click the Rover tab and set the desired Positioning Mode(Figure 3-11). Figure 3-11. Rover ConfigurationAdjust the following RTK Parameters settings:• Under RTK mode in the RTK Parameters section, choose either Extrapolation for RTK float (kinematic) or Delay for RTK fixed (static).– Extrapolation is for low-latency, high frequency output (>= 5 Hz) RTK applications. The rover will extrapolate the base station’s carrier phase measurement corrections when computing the rover's current RTK position.– Delay is for 1 Hz high precision RTK applications. The Rover RTK engine will compute either a delayed RTK position (for the epoch to which the newly received RTCM/CMR message corresponds) or the current stand-alone position (while waiting for new RTCM/CMR messages coming from the base).• Select the antenna status during RTK, either Static or Kinematic.• Specify the Ambiguity fixing level (not applicable to RTK Float). The Ambiguity Fixing Level radio buttons govern the process of the RTK engine, fixing integer ambiguities. The RTK engine uses the ambiguity fix indicator when making decisions whether or not to fix ambiguities. Low, Medium,
Surveying with the ReceiverP/N 7010-0713 3-15and High correspond to the indicator's 95%, 99.5% and 99.9% states, respectively. The higher the specified confidence level, the longer the integer ambiguity search time6. Click the Ports tab and set the following parameters for the serial port (Figure 3-12):•Input drop-down list – select the desired differential correction format.•Period (sec) – leave as is.•Baud rate drop-down list – select a baud rate (i.e., the rate at which differential messages will be transmitted from modem to receiver).•RTS/CTS – select to enable handshaking.TIP TIPUse a 38400 baud rate.Figure 3-12.

Setup and SurveyHiPer XT Operator’s Manual3-169. On the main screen (Figure 3-13), check the LQ field to ensure the receiver obtains differential corrections. Usually, the receiver will start to output the coordinates of the antenna’s phase center along with the solution type within 10–30 seconds. However, spread spectrum radios may take as long as 60 seconds to synchronize.Figure 3-13. PC-CDU Main ScreenThe geodetic coordinates displayed on the Geo tab are always computed in WGS84 and have four solution types.• Standalone – where receiver computes 3D coordinates in autonomous mode without using differential corrections.• Code differential – where the Rover receiver computes the current relative coordinate in differential mode using only pseudo ranges.• RTK float – where the Rover receiver computes the current relative coordinates in differential mode using both pseudo ranges and phases; however, with a float solution, the phase ambiguity is not a fixed integer number and the “float” estimate is used instead.• RTK fixed – where the Rover receiver computes current relative coordinates, with ambiguity fixing, in differential mode.The LQ field reflects the status of the received differential messages and contains the following information:• Data link quality in percentage• Time (in seconds) elapsed since the last received message
Surveying with the ReceiverP/N 7010-0713 3-17• Total number of received correct messages (dependent on the message type received)• Total number of received corrupt messages (dependent on the message type received)If the receiver is not (for some reason) receiving differential corrections, or if none of the ports has been configured to receive differential corrections, the LQ field will either be empty or it will look like this: 100%(999,0000,0000).
