I am working on a project where one of my requirements is to have the UAV recover itself during a freefall. Here's the scenario to clarify what I mean... 

Say the UAV was dropped from a helicopter or balloon at a high altitude and is in a free fall. With a pre-programmed waypoint, I need it to arm itself, stabilize and recover, then fly and land at that location. In theory, this sounds simple by using a Pixhawk and mission planner, but how can I tell it to automatically arm and stabilize once a certain altitude is reached?

  • @Josh - Do want it to arm at an altitude above sea level or an altitude above ground level?

    • Hmm, good question. With my geographic location, I would probably want above sea level.
