How GPS Tracking Works
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.
