The Automated Packet Reporting Service is a digital real time communications system to share tactical information and messages. The most common activity in APRS is to plot the location of moving objects using GPS information, but APRS can also be used for short messaging, weather station telemetry, announcements, and displaying objects on a map. One of the most useful features is the ability to send and receive SMS text messages and text only email via the APRS network.

APRS Software and Information

Automatic Packet Reporting System (APRS)is an amateur radio-based system for real time digital communications of information of immediate value in the local area.[1] Data can include object Global Positioning System (GPS) coordinates, weather station telemetry, text messages, announcements, queries, and other telemetry. APRS data can be displayed on a map, which can show stations, objects, tracks of moving objects, weather stations, search and rescue data, and direction finding data.

APRS data is typically transmitted on a single shared frequency (depending on country) to be repeated locally by area relay stations (digipeaters) for widespread local consumption. In addition, all such data are typically ingested into the APRS Internet System (APRS-IS) via an Internet-connected receiver (IGate) and distributed globally for ubiquitous and immediate access.[2] Data shared via radio or Internet are collected by all users and can be combined with external map data to build a shared live view.

APRS has been developed since the late 1980s by Bob Bruninga, call sign WB4APR, currently a senior research engineer at the United States Naval Academy. He still maintains the main APRS Web site.
