The Raveon model M7 GX transponder is a rugged high-speed UHF and VHF GPS transponder with a built-in 12-channel GPS receiver. It has up to 5 watts of RF power output, and operates as both a GPS transponder for tracking, and a radio modem for sending and receiving data.

The M7 GX automatically reports its status and position are user-configurable intervals and events. With an ultra-fast PLL and protocol, hundreds of M7 GX transponders in the same location can all report, with no interference or loss of data.

The M7 GX Transponder may be user-configured for a variety of applications. One simple command is used to program it to work in any of these configurations:

Transponder: The M7 GX will periodically transmit its location, along with voltage, temperature, input status, speed, direction, and UTC time. It powers-down the radio and GPS when not in use, reducing its average current draw to less than 30mA.
GPS Display: The M7 GX will periodically transmit its location, along with voltage, temperature, input status, speed, direction, and UTC time. It will also receive the location of other M7 GX radios in its radio range for display on a GPS plotter or hand-held GPS connected to the M7 GX’s NMEA RS-232 interface.
RavTrack PC: The M7 GX will periodically transmit its location. It will also output the location of other RV-M7 radios in its radio range for display on the RavTrack PC software program.
Plotter Display: If you already have a gps plotter, you may connect it to the RV-M7 with the –LX option. This gives the unit all the features of the –GX version with the GPS, but uses your GPS NMEA data feed as the source for its GPS signal. It will output the location of other M7 GX radios in its radio range for display on a GPS plotter or hand-held GPS connected to the RV-M7’s NMEA RS-232 interface.
Repeater: Any M7 GX may also be a store-and-forward repeater. With a 3mS attack time, the repeated signal has only milliseconds of latency, and coverage can be 10s of miles.

 

GENERAL FEATURES:
