How It Works
Fastest real-time location updates in the industry.
The M7 GX Transponder has many technological advantages over conventional tracking radios.
These include:
Advanced Modulation Most tracking radios operate at 1200 or 2400 baud over the air. The M7
series operate at 4-10-times that speed using CPFSK2/4 modulation for data
rates as high as 19.2K over the air.
TDMA Channel Access TDMA (Time-Division Multiple Access) is built in every M7 GX radio
modem. With TDMA, 100 vehicles may be tracked with 10-second updates,
and no RF interference. Even when using a repeater.
Data Compression All location transmissions are compressed, allowing not only location to be
sent, but also voltage, temperature, input status, speed, direction, and time
– and do this with less air-time than most radios use to simply transmit
their location.
Fast Switching The M7 transceiver has a fast-lock PLL with a lock-time of only 1mS, and a
T-R turn-around time of less than 3mS. This enables the radio to make true
real-time transmissions in TDMA or conventional modes.
Easy to use, and the M7 GX does it all.
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 RV-M7 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.
