So last year I wrote my own APRS tracker using Pythonista.
APRS stands for Automatic Packet Reporting System
Using a python library for it and pythonistas access to location and the internet I was able to write my own software to report into the system using my Call Sign and display my location of aprs.fi
The following is my code which I never really tided up at all.
