I decided to base my tracker on the Arduino Trackuino APRS Tracker. Mainly because I didn’t want to buy a complete off the shelf product. The Arduino code is fairly simple to modify to suit my requirements.

HAB Tracker

Tracker consists of

GPS, 2 Temp Sensors, Pressure Sensor, Accelerometer, buzzer, HX1 Transmitter, Data logger

Utilising the trackuino code, I have set the buzzer to buzz when below a certain altitude. This will hopefully aid in the final recovery of the package.

The HX1 VHF transmitter will transmit an APRS signal every minute, including its position and certain sensor readings.

A data logger will also record all the data from the sensors and save them to SD card
