TinyTrak-3Plus APRS Interface

GPS Beacon: In combination with a GPS receiver any handheld or mobile radio can broadcast the GPS information.

The beacon features a serial interface which allows PC-programming of the call sign, TX delay, beacon intervals and beacon text. During operation the GPS receiver is connects to the serial port and the audio as well as PTT terminals connect to the radio.

Imagine a moving fox hunt with such a relative simple set-up.

The analysis of the received data is not possible with TinyTrack.

TinyTrak3 is a GPS position encoder which, when connected to a GPS and a radio, will transmit its location at an adjustable rate. TinyTrak3 is a construction project 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.

TinyTrak3Plus is a redesigned TinyTrak3 with a larger voltage regulator that can power a 5V GPS, such as a Garmin GPS18. TinyTrak3Plus has the same features, and uses the same firmware chip, configuration software, and case as the TinyTrak3, but a separate documentation file is available with instructions for the different PCB. TinyTrak3Plus is sold with a case.
