Automatic Packet Reporting System (APRS)

Automatic Packet Reporting System (APRS™) (Formerly "Automatic Position Reporting System") is an amateur radio based digital communication system for real-time exchange of digital information to users on the network. APRS was originally developed by Bob Bruninga, WB4APR more than 20 years ago. It has since evolved into a robust system of interconnected networks.
