Ardupilot Antenna Tracker with PX4 Cube

Hey all,

I have a Pixhawk PX4 Cube running QGroundControl that I’m attempting to integrate a Mavlink antenna tracker with, and looking at antenna trackers I like the Ardupilot tracker firmware installed on a pixhawk the best.

In broad terms, is it possible to go about using the Ardupilot AT firmware controlling a PX4 quad? It looks like the Ardupilot AT would need to split/forward bidirectional Mavlink to QGroundControl, however from what I can tell MavProxy does not support the new PX4 autopilot controls.

Has anyone seen roughly something similar done?
Thanks!
Shawn
