Hi.
I found a cheap 2.4 ghz frequency hopping video to mpeg4 converter with very nice quality and sensitivity that i coupled with a bidirectional 2.4 ghz amplifier and the airborne tracking antenna.
Initial test showed very good results.

Beware that although the item is real i can't say the same for the transaction.
Aliexpress is the only source for it right now i think.

The telemetry is done with the usual 9xtend modems and now i am about to test this

Hi Chris. Can you give me some pointers on how to implement digital video  and secure telemetry?

He he he  your guess is correct.
The code i am flying is heavily altered towards a fixed wing platform.
For example i am working on a safety algorithm that guides the airplane back home when gps is lost. When gps is lost (interference etc.) the airborne directional antenna(s) are used for guiding the airplane back home with the aid of the compass, the barometer and any available RSSI indication.
Of course telemetry and video are now digital and encoded.

Hi Chris,

yes, I moved it to firmwares/fixedwing, as it is fixedwing specific stuff...

But I still wonder why you got this error, I changed it accordingly in all sources... Did I miss something or was that in some of your own code?

Cheers, Felix

I found it, nav.h moved to "firmwares/fixedwing/nav.h" (for fixedwings of course)
