Automatic Position Reporting System

Automatic Packet Reporting System (APRS) is anamateur 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,callsignWB4APR, at theUnited States Naval Academy. The acronym "APRS" was originally derived from his call sign, 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, both Mr. Bruninga and almost all hams use the term "Position".
