In order to solve the problem of poor training effect in UAV controller, developed a software simulation training system of UAV. Systems based on DirectX as the underlying driver, combined with the unmanned aerial vehicle motion and sensor model, building a personnel simulation, environmental simulation, simulation of UAV and sensor simulation and other parts solve real transformation between coordinates and latitude/longitude coordinates, sensor simulation solutions to problems. The system has been successfully applied to UAV control of teaching, results show that the system is high degree of simulation and low demand for environment, stable and reliable operation, training is effective.
