The Automatic Packet Reporting System (APRS) is a digital communications system for the exchange of position data, map objects, short text messages, and other tactical data. Unlike most automatic vehicle location (AVL) systems, APRS is designed as a peer-to-peer system to improve situational awareness, not just to send position data back to a central dispatch center.
While the public APRS network is limited to amateur use, the APRS protocol, most APRS hardware, and many APRS mapping programs can be used for commercial purposes, subject of course to normal radio licensing requirements. Implementing a private APRS network typically requires more design and integration effort than the deployment of a turnkey AVL system, but APRS offers unparalleled flexibility in equipment selection and network design, along with lower hardware cost and no subscription fees.
The Tracker2 is our top of the line APRS tracker. It includes advanced features such as detailed waypoint output to NMEA, Garmin, and Magellan GPS receivers, full APRS digipeater support, remote control and configuration, KISS protocol support, weather station support, and the ability to use almost any combination of those features simultaneously.
The OpenTracker+, successor to the original OpenTracker, is our entry-level APRS tracker, and is available assembled or in kit form. Despite the low price, it's still one of the most advanced APRS trackers available, with support for NMEA waypoint output, SmartBeaconing™, low-voltage inhibit feature, and on-board temperature and voltage telemetry
The OpenTracker, OpenTracker 1x, and OpenTracker 1m are no longer in production, but are still supported.
