APRS is an international network of amateur radio stations providing real-time GPS based vehicle or event position reporting, weather reporting and simple message handling for educational, experimental or emergency use. APRS uses a common radio frequency of 144.800 MHz throughout Europe. Digital repeating (digipeating) is used to extend the range of mobile and low power stations over a wider area. In addition to the radio network internet gateways provide a two-way port to the APRS-IS (APRS Internet System) so that stations local to the gateway can be seen worldwide on APRS viewing programs such as Xastir or UI-View.
