Automatic Packet Reporting System (APRS) is an amateur radio based system for digital communications, most commonly used to automatically report the position (GPS coordinates) of a person or object, or weather data at a remote location. It was developed by Bob Bruninga, WB4APR, at the United States Naval Academy. The acronym “APRS” was originally derived from his callsign, and subsequently expanded to “Automatic Position Reporting System”. As the system was modified and expanded to handle non-position packet data, the meaning of the “P” in the acronym was again changed to “Packet” rather than “Position”. Today, it is common for hams to use either expansion of the acronym.
The Ashe County ARC operates an APRS digipeater on 144.390 MHz from Phoenix Mountain.
