Quadcopter Altitude Reference

Posted by Glen Leeon on April 23, 2014 at 3:32pm

I'm new to all this but I have a question on how UAV determine their height above or below the launch site? I imagine on most flights, you place the UAV on the ground and arm it and it does a check on where it is and then you proceed to altitude above the launch site, but what happens if you start on a cliff and fly down to the beach? Does it not matter? Is the UAV able to calculate heights below its starting point?

Any simple explanation is welcomed.

    Yes, it will use negative altitude when flying below the home altitude.

      Thanks iskess,

      I was hoping that was the case.
