Abstract
A system arranged in an aerial vehicle for determining the position of the aerial vehicle relative to a center of a remote predetermined landing area arranged on a surface. A beam emitter is configured to emit beams towards the surface. A detector is configured to detect the beams reflected from the surface. A control is configured to control the beam emitter to emit beams onto the surface to form a plurality of lines thereon. A processor is configured to detect at least one edge providing a difference in height relative to the surface based on the detected reflected line forming beams. The edge substantially surrounds the predetermined landing area. The processor is further configured to determine the position of the aerial vehicle relative to the center of the remote predetermined landing area based on the detected at least one edge.
