Abstract
Various embodiments of a system and method for landing an unmanned aerial vehicle are described herein. The system includes at least one memory and at least one processor, wherein the at least one memory is operatively coupled to the at least one processor; the at least one processor being configured to control landing of the unmanned aerial vehicle by executing the modified PPN guidance law algorithm, wherein the modified PPN guidance law algorithm comprises: determining a current position for the unmanned aerial vehicle; determining a distance of the current position from a target position; generating at least one velocity command from the determined distance, the velocity command reducing to zero as the distance reduces to zero; and controlling the unmanned aerial vehicle to maintain the velocity thereof at the velocity command, whereby as the unmanned aerial vehicle approaches the target destination, the velocity of the aerial vehicle reduces to zero.
