GPS RECEIVER The RPR 110 GPS receiver can generate real-time position solutions at a rate of 5 solutions per second. You can purchase an option that enables the 110 to output up to 10 solutions per second.
When this happens, a new version of firmware is created. You can request this firmware from Raven. You will need to connect the receiver to a PC and run the included programming software to update the unit. You should check with your dealer for a new versions of firmware.
The receiver uses default settings that should provide reasonable operation without the need for special configuration. ADVANCED MESSAGE FORWARDING The RPR 110 receiver supports advanced message forwarding in systems where the application is designed to take full advantage of this feature. When enabled, all messages received on Port B of the receiver will be time tagged with GPS time and output on Port A in a special format.
At this point, we have the power connected to the mounted receiver and the antenna is connected. Watch the green LED GPS satellite-tracking indicator. The RPR 110 will be looking for satellites, which may take a few minutes. Eventually, if your antenna has a clear view of the sky, the GPS light will flash once for each satellite in view that it is using to calculate its position.
110. If you need to change the WAAS or GPS setups, you can run the receiver software to make the changes. POWER The RPR 110 receiver needs DC power between 9 and 16 Volts. DC power is usually provided by a battery on the machine or via a power adapter of some type.
Items such as electrical motors, generators, alternators, strobe lights, radio transmitters, cellular phones, microwave dishes, radar, active antennas, etc., all generate electrical and magnetic fields which can interfere with the GPS or WAAS signal. Mount the antenna away from such potential sources of interference. The GPS can be de-tuned by close proximity to other objects.
The unit should be operating in full DGPS mode within a few minutes of power on. All configuration and WAAS data is stored in nonvolatile memory inside the RPR 110 110. Configuration changes are made with utility software. Be aware of possible satellite obstructions, which may interfere with GPS operation.

GLOBAL POSITIONING SYSTEM (GPS) GPS is a satellite-based global navigation system created and operated by the United States Department of Defense (DOD). Originally intended solely to enhance military defense capabili-ties, GPS capabilities have expanded to provide highly accurate position and timing information for many civilian applications. An in-depth study of GPS is required to fully understand it, but not to see how it works or appreciate what it can do for you.
DIFFERENTIAL GPS (DGPS) WAAS DGPS works by placing a high-performance GPS receiver (reference station) at a known location. Since the receiver knows its exact location, it can determine the errors in the satellite signals. It does this by measuring the ranges to each satellite using the signals received and comparing these measured ranges to the actual ranges calculated from its known position.
NMEA 0183 standard has been established by the National Marine Electronics Association. The NMEA 0183 standard contains numerous message formats such as the ones described below which the RPR 110 receiver uses to communicate with other devices. RPR 110 NMEA Messages...
