Abstract

Methods, systems, and computer program products are provided for depicting the flight of a formation of a plurality of UAVs. Embodiments include piloting a plurality of UAVs, each UAV being piloted under the control of a navigation computer in accordance with a navigation algorithm and a flight formation algorithm. While piloting each UAV, embodiments typically include reading from a GPS receiver on each UAV a sequence of GPS data representing a flight path of the UAV; depicting the flight of each UAV with 3D computer graphics to create a plurality of UAV flight depictions, including a computer graphic display of a satellite image of the Earth, in dependence upon the GPS data; and coalescing the plurality of UAV flight depictions. Embodiments may also include identifying a deviation of a UAV from its intended position in the formation in dependence upon the coalesced depiction.
