Abstract:
1. A system arranged in a vertical take-off and landing aerial vehicle for determining a position of the aerial vehicle relative to a center of a remote predetermined landing area arranged on a surface, the system comprising: a beam emitter configured to emit beams towards the surface; a detector configured to detect the beams reflected from said surface; a control unit configured to control said beam emitter to emit beams onto said surface to form a plurality of intersecting lines thereon; and a processor configured to detect at least one edge providing a difference in height of the edge relative to the surface, based on the detected reflected line forming beams, wherein said edge substantially surrounds the predetermined landing area, and wherein the processor is further configured to determine the position of the vertical take-off and landing aerial vehicle relative to the center of the predetermined landing area based on the detected at least one edge.
