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.

Products | Argent Data Systems

We are currently expanding our product line to include innovative and low cost voice and data radios for hobbyists and professionals. Our main products are the OpenTracker+ and Tracker2 series of APRS and packet radio devices designed by Scott Miller, N1VG.


Simplex Repeater | Argent Data Systems

This has the effect of doubling the time required to transmit a message, but while a traditional repeater typically costs thousands of dollars and might be semi-portable at best, a simplex repeater can be set up with a single handheld radio and operated from batteries.


OpenTracker+ | Argent Data Systems

The tracker will also report telemetry from its onboard temperature and voltage sensors, and an external counter input can report a cumulative total of counter events or the number of events since last transmission. The OpenTracker+ is an APRS tracker that can also receive data from other stations and has waypoint output capability. Use the OT1+ to encode and transmit data from a supported weather station.


Tracker2 | Argent Data Systems

Plots received positions as waypoints - APRS stations, objects, and items received over the air can be passed to a GPS receiver to be plotted on its map display. Remote control via APRS - Most of the commands available at the console may also be issued through APRS station-to-station text messages. In addition, the transmit and receive frequency and RF power output can be set through the Tracker2, including by remote command.
