This Google Maps Mashup shows real-time information collected from the Automatic Position Reporting System Internet network (APRS-IS). APRS is used by amateur (ham) radio operators to transmit real-time position information, weather data, telemetry and messages over the radio.
A vehicle equipped with a GPS receiver, a VHF transmitter or HF transceiver and a tracker can transmit its location, speed and course. Using this Google Map it is possible to search for any vehicle using its APRS call sign. Alternatively, the map can display the last 500 vehicles that transmitted a movement or all the vehicles at a particular location.
For each vehicle shown on the map it is is possible to view its movements for the last seven days. If you click on a vehicle's map marker you can get information about speed, direction, destination and other vehicles nearby.
If you don't know the call sign of any vehicles you should enter your current location into this map and view all the vehicles around you that use APRS.
