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.
Yes. It is entirely possible.
You can use a FSK modem IC. A couple of simpler ones are the TCM3105 and the MX614.
They both convert serial data to from FSK and work very well. The TCM3105 requires more adjustment with pots etc though to get it working
(It is also possible to use a microcontroller with a DAC to send FSK, and to receive using an ADC, but the chips above work well.
Hello.
I have a simple question, so I did not create a separate topic.
I want to collect a managed model controlled by mobile communication.
An analog of a military drone.
Is there such functionality for the controllers, if so which ones?
I did not understand this for a long time, so I could skip something.
I really hope for understanding.
Thanks to all.
