Abstract

Systems and methods are provided for training a user to control an unmanned aerial vehicle (UAV) in an environment. The systems and methods provide a simulation environment to control a UAV in a virtual environment. The virtual environment closely resembles a real flight environment. The controller used to transmit flight commands and receive flight state data can be used in both simulation and flight modes of operation.
