Is there an easy and open-source way to take an aircraft’s telemetry (primarily GPS), inject it into the audio channel of an FPV transmitter, and decode it on the ground to drive an ardutracker?
I would like to eliminate the separate weight, interference and power requirements of my current 915 telemetry radios, and my Vtx is higher-powered too. I’m using Ardupilot, but the Ardutracker solution assumes you’re working separate telemetry radios. I know there are some commercial solutions that do this (e.g. EZOsd), but they’re very pricey.
I rate myself a noob at radio and programming, somewhat better at soldering.
