APRS is a system that allows to report the geographical position of stationary or moving objects in combination with a GPS receiver with radio signals (cars, airplanes, hikers, bikers, ISS etc.). In addition to position data, telemetry data can be acquired remotely (e.g. temperature, wind-speed, any parameter that can be measured electronically).

The map below is updated every 3 minutes and shows the position of the presently active APRS amateur radio stations in
