Claim 4:
5. The system of claim 1, wherein the processing apparatus is configured to:
control the propulsion mechanism to cause the unmanned aerial vehicle to fly to a second location above the landing surface;
control the propulsion mechanism to cause the unmanned aerial vehicle to descend toward the fiducial on the landing surface;
responsive to reaching a predetermined height above the landing surface, control the propulsion mechanism to cause the unmanned aerial vehicle to hover at the predetermined height above the landing surface until error estimates for a pose and velocity of the unmanned aerial vehicle meet stability conditions; and
responsive to the stability conditions being met, control the propulsion mechanism to cause the unmanned aerial vehicle to perform a final approach to touch down on the landing surface.
