TinyTrak3Plus is an APRS GPS position encoder which, when connected to a serial GPS and a radio, will transmit its location at an adjustable rate. TinyTrak3Plus is the fourth generation in TinyTrak series, and is available as a kit construction project, or as a built and tested unit, providing an inexpensive way to build a mobile tracker without the need for a full TNC. It is configured by connecting to a computer’s serial port, and running a simple configuration tool which allows setting of all user options. After that, the computer can be disconnected, and a GPS connected in its place for operation.

TinyTrak3Plus has the following features:

  1. Decodes any NMEA-0183 compatible serial GPS sending $GPRMC or $GPGGA sentences. USB only GPSs will not work.
  2. Can provide 5V power to an external GPS (such as the Byonics GPS1 or GPS2).
  3. Transmits position, altitude, speed, heading, and timestamp (hour/minute/seconds or day/hour/minute).
  4. Supports SmartBeaconing, which adjusts transmission rates to speed and turning.
  5. Can transmit position in MIC-E, NMEA, or APRS ASCII text format.
  6. Two configurations, with all user options switchable.
  7. Burst after voice / Send Position Now input.
  8. Handles position resolution down to 7 inches.
