Use the WinFLASH utility to upgrade the SiteNet 450 software. 14 SiteNet 450 Operation Manual SN450.book Page 15 Friday, October 5, 2001 5:01 PM CHAPTER Installing the SiteNet 450 Network In this chapter: ■ Introduction ■ Physical Description ■ Mounting the SiteNet 450 on a Machine ■ Cabling Configurations ■ Antenna Description SN450.book Page 16 Friday, October 5, 2001 5:01 PM 3.1 Installing the SiteNet 450 Network Introduction Before setting up the equipment in the field, verify that each radio-modem is set to the same channel and wireless data rate. Also verify that the radio-modem’s Data Port settings are 38400 and parity none. Set the serial port settings for both base and rover GPS receivers to 38400 bps, 8 bits, parity none, and 1 stop bit. For more information about general GPS receiver setup information, refer to the GPS receiver manual. If these settings are not available, use the WinFLASH utility to set the radio-modem’s serial port settings to those of the GPS receiver. Note – High-power signals from a nearby high-power radio station or radar transmitter can overwhelm the radio-modem circuits. This does not harm the instruments, but can prevent them from functioning correctly. To avoid problems, try not to use the radio-modems within 400 meters (1300 feet) of powerful radar, television, or other transmitters. Low-power transmitters such as those in portable phones and walkie-talkies normally do not interfere with SiteNet 450 radio-modem operations unless they are tuned to the same channel. Always monitor frequency before and during operation. Transmit only on a clear channel. Also, to avoid possible interference with GPS reception, keep the base radio-modem antenna as far as possible from the GPS antenna. A minimum of 3 meters (10 feet) is recommended. For more information about the precautions when using certain frequencies that can interfere with GPS operation, refer to Selecting Communications Radios, page 47. This is a copy of Trimble’s publication Using Radio Communication systems with GPS Surveying Receivers (PN 1-612-0082-2/94). Installation as a Repeater To achieve coverage to all points in a survey area, a SiteNet 450 network may include up to two repeaters under certain conditions. The repeaters retransmit data packets in a way that avoids interference 16 SiteNet 450 Operation Manual SN450.book Page 17 Friday, October 5, 2001 5:01 PM Installing the SiteNet 450 Network with the base and each other. The operation of the repeaters is transparent to the rovers. The rover will use the data packets from the base or repeater, whichever it receives first. The option to include a repeater in a network depends on the selected wireless data rate and the broadcast information content. Table 3.1 illustrates when a repeater may be used in a network for various wireless data rates, RTK formats, and RTK epoch rate. Table 3.1 Repeater use in networks Wireless data rate (bps) DGPS CMR at 1 Hz RTCM 2.x at 1 Hz 4800 9600 2 - Two repeaters may be used 1 - One repeater may be used 0 - No repeaters may be used 3.2 Physical Description The SiteNet 450 radio-modem is encased in a rugged, waterproof metal case.

An optional infrastructure installation kit comes with an antenna base and 5 dB whip antenna tip. The 5 dB antenna measures 81 cm (32 in) in length, including the base. See Figure 3.11. 0 dB low-profile antenna SiteNet 450 Antenna base Figure 3.11 32 SiteNet 450 with antennas SiteNet 450 Operation Manual 5 dB tip SN450.book Page 33 Friday, October 5, 2001 5:01 PM Installing the SiteNet 450 Network 3.5.1 Antenna Considerations Note – Please use care when removing the radio antenna. The SiteNet 450 antenna contact tip is designed for maximum efficiency and very low loss. To maintain its integrity, do not remove the top cap from the radio housing. Make sure that you mount the base and repeater radios as high as possible. An increase in the antenna height increases your line of sight and is the most effective way to increase the radio’s range. Consult your license for the legal limits on antenna height. Line-of-Sight Obstruction Objects placed near the antennas, especially metal objects, can severely limit antenna efficiency. If an antenna is to be mounted on a mast, make sure it is mounted so that its radiating element is completely above the top of any obstructing source, if possible. Figure 3.12 shows the optional infrastructure antenna mounting for the SiteNet 450.

In some countries, the unit can be used without obtaining an end-user license. Other countries require end-user licensing. Consult your local communications governing agency for licensing information. Before operating a SiteNet 450 radio-modem, 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 SiteNet 450 radio-modem for the location or country of use. Note – This device complies with Part 15 of the FCC Rules. Operation is subject to the condition that this device does not cause harmful interference. 4.2 Type Approval Warning – Changes or modifications to this equipment not approved in writing by Trimble Navigation Limited voids your authority to operate the equipment. Type 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 radio-modem 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. 38 SiteNet 450 Operation Manual SN450.book Page 39 Friday, October 5, 2001 5:01 PM Regulations and Safety 4.3 Licensing Many countries require that the operator of a radio or radio-modem obtain a license prior to operating it. Consult your local communications governing agency for licensing information. Obtaining an operator’s permit or license for the SiteNet 450 for the location or country of use is the responsibility of the end user. Before operating this radio-modem, you are legally required to obtain frequency licenses as required by the country of use. Please contact your local communications governing agency for the licensing requirements for each of these radio-modems. 4.4 Safety Exposure to RF energy is an important safety consideration. The FCC has adopted a safety standard for human exposure to radio frequency electromagnetic energy emitted by FCC-regulated equipment as a result of its actions in General Docket 79-144 on March 13, 1986. Proper use of this radio-modem results in exposure below government limits. The following precautions are recommended: • Do not operate the transmitter when someone is within 0.6 meter (2 ft) of the antenna. • Do not operate the transmitter unless all RF connectors are secure and any open connectors are properly terminated. • Do not operate the equipment near electrical blasting caps or in an explosive atmosphere. • All equipment must be properly grounded according to Trimble installation instructions for safe operation. • All equipment should be serviced only by a qualified technician.

But a truly successful survey is not just a matter of making sure that you have all of the equipment; you must also ensure that you optimize the usage of these new tools for the highest productivity. The GPS receiver is trying to measure very faint radio signals from satellites orbiting at 22,000 kilometers in space. There are many factors that can hinder the receiver’s ability to perform. For example, placing your hand over the antenna or setting up the antenna under a tree are factors that have already proven to interfere with GPS signal reception. As GPS receivers developed, their processors have become more sensitive to incoming data flow. This provides an increase in accuracy by extracting more information out of the GPS radio signal. But with this gain in accuracy, there is an increased susceptibility to other radio signals. The receiver is now more sensitive to the incoming GPS signal, and consequently it is also more sensitive to other incoming radio signals. This means that communications radios, such as those commonly used by surveyors, can sometimes create difficulty with the GPS signal reception. There are some very simple steps you can follow to remove the effects of radio interference on the GPS receiver. First, you should be aware of the type of communications equipment you buy and understand its characteristics. Secondly, a little care in using communications radios can greatly decrease your chances of experiencing any interference with satellite tracking. 46 SiteNet 450 Operation Manual SN450.book Page 47 Friday, October 5, 2001 5:01 PM Using Radios with GPS B.2 Selecting Communications Radios If you do not already have communications radios, and are thinking of buying them to supplement your survey activities, there are a number of factors to keep in mind before purchasing: • Some frequencies can cause interruptions of GPS tracking. • Some communications equipment creates spurious signals not related to their frequency that can interfere with satellite tracking. • Powerful communications transmitters can create such a strong radio signal that the GPS signal cannot be identified. Most communication transmitters emit overtones of their assigned frequency. If these overtones line up with the GPS frequency, they can filter into the GPS equipment and interfere with the satellite tracking. Some communication transmitters emit more of these overtones than others. But the number of overtones can be difficult to determine and it is not the most important factor when considering this nuisance parameter. To avoid being effected by transmitter overtones, avoid those frequencies that lie within the GPS frequency range.

These are extremely difficult to predict. The only way to know if your receiver is being effected by spuriously emitted signals is to test the communication equipment with the GPS receiver. If you plan to buy a new radio, test it with your existing GPS equipment to determine if any problems exist. Communications equipment that uses more power is more likely to create signals from which the GPS signal cannot be extracted. This typically occurs from signals emitted from the radio transmitter box and not its antenna. Non-GPS signals enter the GPS system through the GPS antenna and not through the receiver. Therefore, most of the effects of non-GPS signals can be minimized by physically separating your radio and GPS equipment. B.3 Useful Field Procedures There are a few useful field procedures you can follow to minimize the effects of your radio. Since most of the radio signal in the GPS band is emitted directly from the radio transmitter box and received via the GPS antenna, make sure the GPS antenna is separated from the radio transmitter by 2-3 meters (7-10 feet). If you are still experiencing difficulties at this distance, the GPS signal may be getting overpowered by the radio transmissions. In this case, you can either separate the equipment even more or shield the radio transmitter. As you move farther away from the source of the transmission, radio signal strength drops as a square of the distance. Therefore, if there is a problem, separate the GPS antenna and radio even more to lessen the strength of the radio signal received at the GPS antenna. If you are using a geodetic antenna, you can use the antenna’s ground plane to shield the radio waves. In fact, you can shield the antenna from the radio signal by moving behind nearby objects such as a car or tree. If you cannot move away from the GPS antenna, move the radio below the level of the GPS antenna ground plane. This is not ideal, but may help in those cases where you are left with no alternative. SiteNet 450 Operation Manual 49 SN450.book Page 50 Friday, October 5, 2001 5:01 PM B.4 Using Radios with GPS Summary Using communications radios with GPS receivers requires some special considerations. By striving to extract the utmost accuracy from the GPS system, receiver designs have made greater use of the radio spectrum. However, the methods used to increase performance and accuracy also make GPS receivers more susceptible to receiving other radio signals. Radio signals in the GPS band arise from a few different sources. Some radio transmitters produce overtones of their frequency, which lie within the GPS P-code frequency range. Others create random, spurious signals, which affect GPS signal reception. Still other radio systems use high power levels to boost communication range and create noise that limits the GPS signal tracking. These are all characteristics to avoid when purchasing or using communications equipment in conjunction with GPS. Before using radios on a full-fledged survey job, it is a good idea to test the communications equipment to determine if it effects the GPS signal reception in any way. Testing radios with the GPS equipment is especially important if you are considering purchasing new radios. Make sure to always: • choose the communication frequency of your radios carefully so they do not transmit on or create harmonics in the frequency range of GPS. • test them with your GPS receivers. • if problems arise, put some distance between the radio transmitter case and the GPS antenna. Also, shielding the radio transmitter should minimize the effects of radio signals on the GPS signal reception. Radio signal strength drops as a function of distance. The greater the separation between the GPS antenna and the radio transmitter, the less likely you are to experience interruptions in satellite tracking. 50 SiteNet 450 Operation Manual SN450.book Page 51 Friday, October 5, 2001 5:01 PM Index Numerics 8-pin Bendix connector 44 antenna contact tip 19 description of 32 location of 17, 34 connectors and indicators 18, 43 Bendix 25, 44 infrastructure cable 29 pinout 44 power and I/O cable 26 data modem 6 data, raw GPS 2 base station, installations 27 base/repeater 6 electrical specification 42 environmental specification 42 cables configurations available 25 infrastructure power 27 machine installations 26 machine service 7, 31 SiteNet 450 configurations 25 troubleshooting for 29 cap bottom 44 top 19, 33 CMR, format 2 communications radios 47 field procedures 49 frequency band 4 bands to avoid 48 range 43 green LED 19 SiteNet 450 Operation Manual 51 SN450.book Page 52 Friday, October 5, 2001 5:01 PM Index hardware, performance 2 humidity, specification 42 indicator, LED 19 installing.
