  • Publication number: 20210247781
    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.

  • Patent number: 10114384
    Abstract: A method for implementation of a formation flight path coordination for a scalable group of Unmanned Arial Vehicles (UAVs) including a recursive architecture with a leader UAV and a plurality of follower UAVs in communication with the leader UAV, the method comprising the steps of: receiving formation commands for the UAVs of the group from a ground controller station (GCS), the formation commands including positional and velocity information for implementation by onboard processing systems, the formation commands received on a first communication channel established between the leader UAV and the GCS; sending information from the formation commands by the leader UAV to the plurality of follower UAVs belonging to the leader UAV using a second communication channel established between the plurality of follower UAVs and the leader UAV, the second communication channel separate from the first communication channel; receiving updated formation commands for the flight path from the GCS on the first communication c
