HX1 Arduino APRS Tracker

In this video we show how to build you own automatic packet reporting system (APRS) tracking system. This uses an Arduino, a GPS receiver, and a HX-1 radio to report the position of the system on the APRS frequency (144.39 MHz). In addition to showing the schematic and circuit diagram, we discuss the software you’ll need to get the system running. We then test it in a high altitude weather balloon and show that the system operates in extreme environments (over 81,000 ft altitude).
