US Patent 8626361 System and methods for unmanned aerial vehicle navigation

A system includes an unmanned aerial vehicle (UAV) configured to be equipped with data representing a first UAV flight plan, and a ground station configured to control the UAV. The ground station is operable to receive, at a first time, a first data set representing at least one flight path of at least one aircraft, calculate a second UAV flight plan to avoid the at least one flight path of the at least one aircraft, the second UAV flight plan being based on the data representing the first UAV flight plan and the first data set representing at least one flight path of the at least one aircraft, and transmit data representing the second UAV flight plan to the UAV.
