3 Installing the SiteNet 450 Network16 SiteNet 450 Operation Manual3.1IntroductionBefore 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 RepeaterTo 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 SN450.book Page 16 Friday, October 5, 2001 5:01 PM

SiteNet 450 Operation Manual 17Installing the SiteNet 450 Network 3with 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. 3.2Physical DescriptionThe SiteNet 450 radio-modem is encased in a rugged, waterproof metal case. It has an antenna mount on the top cap, and a connector and LED on the bottom cap.

SiteNet 450 Operation Manual 33Installing the SiteNet 450 Network 33.5.1Antenna ConsiderationsNote – 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 ObstructionObjects 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.SN450.book Page 33 Friday, October 5, 2001 5:01 PM

B Using Radios with GPS46 SiteNet 450 Operation ManualB.1 IntroductionNote – For more information, refer to the Trimble publication “Using Radio Communication Systems with GPS Surveying Receivers” (PN 1-612-0082-2/94).“GPS receiver, antenna, tripod, tribrach, tape, cones, flagging, radio...”, such is the checklist of most GPS surveyors preparing for a day of observations. 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.SN450.book Page 46 Friday, October 5, 2001 5:01 PM

SiteNet 450 Operation Manual 47Using Radios with GPS BB.2 Selecting Communications RadiosIf 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.SN450.book Page 47 Friday, October 5, 2001 5:01 PM

SiteNet 450 Operation Manual 49Using Radios with GPS BSome communication transmitters and receivers also emit spurious signals. 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 ProceduresThere 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.SN450.book Page 49 Friday, October 5, 2001 5:01 PM

B Using Radios with GPS50 SiteNet 450 Operation ManualB.4 SummaryUsing 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.SN450.book Page 50 Friday, October 5, 2001 5:01 PM
