Has anyone used a pixhawk as a standalone device to assist in mapping using a full-sized fixed wing craft?
I'm thinking about setting up a pixhawk +GPS + 3dr radio in a box that would be powered by a 5v BEC. A camera trigger would be connected to the pixhawk. The way that it would need to work is to fly to the target area, then set the cam trigger distance parameter so that the pixhawk could begin to trigger photos with the correct amount of overlap, and the resulting log would have accurate GPS tags via the trigger events. Once the area was done, set the cam trigger distance back to 0 to stop taking photos.
So is this viable? If the pixhawk is disarmed, can it still be put into auto mode so that it can begin to send the trigger command to the camera? Can this just be done using a tablet and no RC remote?
Is there anything else that would need to be done to make this work?
