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.

APRS over PSK-63 is a new mode allowing mobile or fixed station APRS operation on HF from remote areas away from the coverage of the VHF APRS network. Using 10.1497 MHz as a common frequency in Europe and the USA a typical range of 400 to 2000 miles from fixed and mobile stations using modest equipment can be expected. There are several Igates operating in Europe, Australia and the USA transferring received packets and messages from 10.1497 MHz to the APRS-IS.
