Getting Started Guides SNM910 Site-Net Modem Safety Information Before you use your Trimble product, make sure that you have read and understood all safety requirements. Use and care This product 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.
SNM910 Site-Net Modem Getting Started Guide Unauthorized modification of the units voids the Type approval, the warranty, and the operational license of the equipment. Exposure to radio frequency radiation For 450 MHz radio 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.
Getting Started Guides For Bluetooth radio The 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 20 cm or further from the human body. The internal wireless radio operates within guidelines found in radio frequency safety standards and recommendations, which reflect the consensus of the scientific community.
SNM910 Site-Net Modem Getting Started Guide The antennas that can be used (country dependent) with the 450 MHz radio are 0 dBi and 5 dBi whip antennas. The antennas that can be used (country dependent) with the 900 MHz radio are 0 dBi, 3 dBi, and 5 dBi whip antennas. The antennas that can be used (country dependant) with the2.4 GHz radio are 2 dBi and 8 dBi whip antennas.
Getting Started Guides WARNING – Use caution when connecting battery cable's clip leads to a vehicle battery. Do not allow any metal object or jewelry to connect (short) the battery's positive (+) terminal to either the negative (-) terminal or the metal of the vehicle connected to the battery. This could result in high current, arcing, and high temperatures, exposing the user to possible injury.
SNM910 Site-Net Modem Getting Started Guide WARNING - The external power adaptor and its associated power cord and plug are not intended to be installed outdoors, or in a wet location. Use of Power over Ehternet SPSx61 only WARNING - When this product is connected to a Power over Ethernet connection, the source of the Ethernet power must meet IEEE 802.11af, and its DC output (Ethernet power source) must be completely isolated from earth ground (floating), or a shock hazard may exist.

Glossary 1PPS almanac Pulse-per-second. Used in hardware timing. A pulse is generated in conjunction with a time stamp. This defines the instant when the time stamp is applicable. A file that contains orbit information on all the satellites, clock corrections, and atmospheric delay parameters.
SNM910 Site-Net Modem Getting Started Guide carrier phase Is the cumulative phase count of the GPS or GLONASS carrier signal at a given time. cellular modems A wireless adaptor that connects a laptop computer to a cellular phone system for data transfer. Cellular modems, which contain their own antennas, plug into a PC Card slot or into the USB port of the computer and are available for a variety of wireless data services such as GPRS. CMR/CMR+ Compact Measurement Record.
Glossary the data has been collected by postprocessing. differential GPS DOP See real-time differential GPS. Dilution of Precision. A measure of the quality of GPS positions, based on the geometry of the satellites used to compute the positions. When satellites are widely spaced relative to each other, the DOP value is lower, and position accuracy is greater. When satellites are close together in the sky, the DOP is higher and GPS positions may contain a greater level of error.
SNM910 Site-Net Modem Getting Started Guide Features can be classified as surface or non-surface features, and again as points, lines/breaklines, or boundaries/areas. firmware The program inside the receiver that controls receiver operations and hardware. GLONASS Global Orbiting Navigation Satellite System. GLONASS is a Soviet space-based navigation system comparable to the American GPS system. The operational system consists of 21 operational and 3 non-operational satellites in 3 orbit planes.
Glossary MSAS MTSAT Satellite-Based Augmentation System. A satellitebased augmentation system (SBAS) that provides a freeto-air differential correction service for GPS. MSAS is the Japanese equivalent of WAAS, which is available in the United States. multipath Interference, similar to ghosts on an analog television screen, that occurs when GPS signals arrive at an antenna having traversed different paths. The signal traversing the longer path yields a larger pseudorange estimate and increases the error.
SNM910 Site-Net Modem Getting Started Guide the source-table. OmniSTAR PDOP The OmniSTAR HP/XP service allows the use of new generation dual-frequency receivers with the OmniSTAR service. The HP/XP service does not rely on local reference stations for its signal, but utilizes a global satellite monitoring network. Additionally, while most current dual-frequency GPS systems are accurate to within a meter or so, OmniSTAR with XP is accurate in 3D to better than 30 cm. Position Dilution of Precision.
Glossary supported as Version 2. RTK real-time kinematic. A real-time differential GPS method that uses carrier phase measurements for greater accuracy. SBAS Satellite-Based Augmentation System. SBAS is based on differential GPS, but applies to wide area (WAAS/EGNOS/MSAS) networks of reference stations. Corrections and additional information are broadcast via geostationary satellites. signal-to-noise ratio SNR.
SNM910 Site-Net Modem Getting Started Guide improves the accuracy and availability of the basic GPS signals over its coverage area, which includes the continental United States and outlying parts of Canada and Mexico. The WAAS system provides correction data for visible satellites. Corrections are computed from ground station observations and then uploaded to two geostationary satellites.
