What is APRS?

APRS (Automatic Packet Reporting System) is a digital communications system that uses packet radio to send real time tactical information (on amateur radio frequencies). The APRS network is used by ham radio operators all over the world. Information shared over the APRS network is for example coordinates, altitude, speed, heading, text messages, alerts, announcements, bulletins and weather data. APRS has been developed by Bob Bruninga, callsign WB4APR. More information about APRS can be found at www.aprs.org or at wikipedia.
