Research on the ground control system of quadrotor unmanned aerial vehicles

The quadrotor unmanned aerial vehicle (UAV) has been a focus for unmanned aerial vehicles. Ground control system (GCS) is an important part of the quadrotor UAV flight control system, and it can promote the flight performance and safety of quadrotor UAVs. In this paper, a quadrotor UAV GCS is designed and implemented, and the GCS realizes the following functions, including receiving and storing of the flight data, the real-time localization utilizing the customization of electronic maps like MapX and Google Earth, the visual display of flight states via virtual instruments and the waypoint planning. Outdoor experiments have been done to verify the GCS´s performance. It can be concluded that the proposed GCS in this paper can work stably, and it can guarantee the integrity of the flight data, the accuracy of the instruments display and map localization.
