Raveon’s RavTrack utilize VHF and UHF Radio frequencies to transmit the GPS position of vehicles, assets, and personnel.
GPS Satellites send signals down to earth.
Raveon’s RavTrack GPS transponder receives the GPS signal, and computes its location.
The GPS Transponder transmits the position and status of the tracked vehicle over UHF or VHF radio channels.
Another Transponder is located on a tall tower or hill, and configured as a “Repeater”. Every position/status message is receives over the radio channel is automatically re-broadcast to the base station.
At headquarters, another Transponder is configured as a Base receiver, and receives the position/status message from the radio channel. It outputs this information using its serial port.
Connected to the serial port of the base receiver, a Windows PC running RavTrack PC processes the message from the tracked vehicle, checks it against pre-set rules, logs it for historical recall, and saves it to an SQL database.
Any number of workstations may also see the location and status of all vehicles using RavTrack PC. RavTrack PC on a workstation will query the SQL database, and display the GPS tracking information in real-time.
