A design of high-precision positioning system of UAV based on the Qianxun location network

To deal with the problem that the traditional single-point positioning method cannot meet the application demands of positioning precision, this paper designs a high-precision positioning system of unmanned aerial vehicle (UAV) based on the Qianxun location network by means of the network Real-Time Kinematic (RTK) technology. As the first commercial BeiDou ground based augmentation system (GBAS), Qianxun location network provides embedded software development kit (SDK) to obtain differential data which can correct positioning data with errors. As a result, the positioning information of high precision can be acquired. To demonstrate the performance of the designed system, several tests are conducted. It is concluded that the designed positioning system has the characteristics of low cost, small size and high precision, along with the convenient installation on UAV.
