ArgentData OT3 APRS Tracker/Digipeater


The Tracker3 is the successor to our popular Tracker2 series. It features a much more powerful 32-bit processor with improved DSP capabilities, better telemetry support, USB, and more room for expansion.

  • 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. When used with a supported Garmin or Magellan GPS receiver, waypoints will be created with appropriate map symbols, comment text, and elevations.
  • KISS support - Use with any packet program that supports the standard KISS interface protocol.
  • APRS Digipeater - Supports multiple aliases, WIDEn-n and TRACEn-n style callsign substitution with dupe checking, hop count limiting, and optional preemption. May be used simultaneously with tracking and KISS functions.
  • Command console - A traditional TNC2-style serial console provides a simple, platform-independent configuration interface. Additionally, APRS station-to-station messages may be sent and received from the command line.
  • Remote control via APRS - Most of the commands available at the console may also be issued through APRS station-to-station text messages. This allows the unit to be reconfigured from anywhere in the world with APRS access. Access can be limited by callsign and through the use of a secure one-time-password scheme.
  • Upgradeable - Firmware updates are free and easy to install. Firmware images can be downloaded directly from the website with the Windows-based configuration utility, or they can be transferred to the unit from any XMODEM-capable terminal program for cross-platform compatibility.
  • Flexible and Expandable - Extra analog inputs and digital I/O lines, plus a Dallas 1-wire bus, allow connection of a wide variety of devices.
  • SmartBeaconing™ - APRS tracking with SmartBeaconing™ support for automatic beacon rate control, compressed format support for shorter packets and better precision, and timeslotting for efficient, coordinated channel usage.
  • Weather Station Support - Supports Peet Bros, AAG 1-wire, and LaCrosse WS-2300 series weather stations.
  • On-board temperature and voltage telemetry (OT2m only)
  • Scripting - A simple scripting and macro language allows a degree of flexibility and programmability not found in other trackers.
  • Dual serial ports (via splitter cable for OT3m, or front-panel data jack for T3-135).
