APRS Information

APRS (Automatic Packet Reporting System) is a digital communication system used by amateur radio operators to transmit real-time data such as GPS locations, messages, weather information, and telemetry over radio frequencies.

Overview

APRS is a radio-based system for real-time digital communication that allows users to share information of immediate value in a local area or globally via the Internet. It was developed in the late 1980s by Bob Bruninga (WB4APR) and has since become a widely used protocol in the amateur radio community. The system transmits small packets of data over radio waves, which can include GPS coordinates, short text messages, weather telemetry, and other sensor data.
