3 Characteristics and Specifications This chapter briefly summarizes general characteristics and specifications of the TRIMMARK 3 radio modem. 3.1 Antenna Gain The antennas supplied with the TRIMMARK 3 do not increase the energy radiated by the radio modem. They concentrate the energy from the radio modem in a particular direction. The degree to which they concentrate radio frequency energy in any particular direction is called directivity and is measured in dB, or decibels.
3 Characteristics and Specifications Figure 3-1 shows the radiated energy patterns of the UHF omnidirectional antennas used with the radio modems. All omnidirectional antennas must be oriented vertically when used. top view Azimuth 0 dB 5 dB ground level view 45˚ 12˚ Elevation Figure 3-1 Omnidirectional Antenna Gain Patterns The top view shows radiated energy patterns in the horizontal, or azimuth plane of the antennas, the plane that perpendicularly bisects the length of the antenna.
3 Characteristics and Specifications The ground level view shows radiated energy patterns in the vertical, or elevation, plane of the antennas. Much of the energy from the 5 dB antenna is concentrated in elevation to within ±12 ° of horizontal. A rover antenna within this sector receives stronger signals from a 5 dB antenna. However, at angles greater than 12 ° from horizontal, the 0 dB gain antenna radiates more energy.
3 Characteristics and Specifications 3.1.2 Directional Antennas Two directional antennas, a 9 dB Yagi and a 12 dB Yagi antenna, are available as options, dependent on applicable governmental regulations. Figure 3-2 shows the radiated energy patterns of the directional antennas that can be used with the radio modems. The solid line depicts the directional antennas as compared with the dashed lines representing the omnidirectional antennas.
3 Characteristics and Specifications A Yagi antenna focuses the radiated power into a directional transmission used for straight lines (±20 ° for the 9 dB directional antenna or ±17 ° for the 12 dB directional antenna ). Since most of the power is focused in one direction, a Yagi antenna transmits further in this direction than an omnidirectional antenna. The line-of-sight range increase for a unit using the 9 dB directional antenna is about 1.6 times that obtained using the 5 dB omnidirectional antenna.
3 Characteristics and Specifications 3.2 Broadcast Network The following sections describe the frequency bands, channel spacings and wireless data rates available with the TRIMMARK 3 radio modem. 3.2.1 Frequency Band and Channel Selection The TRIMMARK 3 Base/Repeater radio modem operates in one the following frequency bands: • 410 to 420 MHz (UHF) • 430 to 450 MHz (UHF) • 450 to 470 MHz (UHF) Each unit operates in one of these bands, not across bands.
3 Characteristics and Specifications 3.2.2 Wireless Data Rate The wireless data rate is the speed, in bits per second (bps), at which the base unit transmits data to the rover unit. The TRIMMARK 3 can be used at 4800, 9600 or 19200 bps. Note – Each radio modem in a wireless data network must have the same wireless data rate and channel spacing. 3.2.3 Transmit Power The TRIMMARK 3 can be used as a base transmitter or repeater. Each unit can be configured to 2, 10 or 25 Watt power output.

4 Troubleshooting This chapter lists status messages and troubleshooting tips which can be used to help isolate and correct system configuration or operational issues. Status messages may be displayed as a one or two line message on the front panel of the unit. Two line messages listed below are separated by a comma. 4.1 Status Messages Battery Low The battery voltage is below 11.6 volts. Replace the battery as soon as possible. Battery Low, Radio Turned Off The battery voltage has dropped below 10.
4 Troubleshooting Comm Port Error, Check Data Rate The communications protocol between the GPS receiver and the radio is incompatible. With WinFLASH or the Data Collector reconfigure the GPS and Radio Modem protocols to the same settings. Warning:, Radio Hot The radio is approaching, but has not exceeded it’s maximum operating temperature. This may occur due to high data rate transmission at maximum power output (25W), and/or operating the unit in direct sunlight.
4 Troubleshooting Connect Antenna, to Radio The radio modem is attempting to transmit but does not sense an antenna connected to the antenna port. Connect the radio antenna to the unit. If the antenna is physically connected to the unit, the cable and/or antenna may have failed. This message will not appear if the unit is configured as a rover, even if there is no antenna connected. ERROR:, Bad Radio Config The radio was configured incorrectly. This may occur after upgrading the radio firmware.

A Using Radio Communication Systems with GPS Surveying Receivers Trimble Publication 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.
Using Radio Communication Systems with GPS Surveying Receivers A 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.
A Using Radio Communication Systems with GPS Surveying Receivers . Table A-1 RF Bands to Avoid When Using GPS Surveying Receivers From this Frequency To this Frequency 781.210 794.210 607.300 620.300 520.806 529.473 404.866 413.533 390.605 397.105 312.484 317.684 303.650 310.150 260.403 264.736 242.920 248.120 223.202 226.917 202.433 206.766 195.302 198.552 173.602 177.228 156.242 158.842 151.825 155.075 142.038 144.401 134.955 137.844 130.201 132.368 120.186 124.
Using Radio Communication Systems with GPS Surveying Receivers A Some communication transmitters and receivers also emit spurious signals. These are extremely difficult to predict. So, the only way to know if your receiver is being hampered by spuriously emitted signals is to test the communication equipment with the GPS receiver. If you plan to buy a new radio, the best course of action is to test it with your existing GPS equipment, to determine if any problems exist.
A A.2 Using Radio Communication Systems with GPS Surveying Receivers Useful Field Procedures There are a few useful field procedures that 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).
Using Radio Communication Systems with GPS Surveying Receivers A.3 A 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.
