Here is a video of a home-built setup based on Raspberry-Pi [1] and an opensource software stack on a fixed-wing aircraft. For use on quadcopters the problem is the latency. Analog FPV systems can achieve around ~20ms latency.

- SkyDrone 9y agoYou are right, with the current state oft LTE and a digital video pipeline we are not yet competitive to analog latency. On our Sky Drone FPV system we get a glass-to-glass latency of ~150ms which is good enough for controlling a drone at some altitude. It is not good enough for competitive racing though. But I am confident the time will come. The next gen cellular network aka "5G" will reduce the network latency significantly and with some new technologies on image sensors (super high framerate, global shutter, ...), I am confident that it will eventually make analog setups obsolete.
