Abstract

A system for predicting the movement of a surface for autonomous landing of unmanned aerial vehicles thereon. At least two beam emitters are each movable to measure along at least one line on the surface. The lines measured by the two beam emitters are crossed so that they have at least one point of intersection in common. A control module. A detector is configured to detect reflected beams. A processor is configured to process measurements including estimating continuously a plane to the surface by measurements during a time interval. A storage module is configured to store the processed measurements.
