Research on High Precision Dynamic Relative Positioning Technology Based on the Third Generation BDS

With the rapid development of information technology, the demand for high precision positioning technology is increasing in human scientific research and life. China's Third-generation BeiDou navigation satellite system has also launched global navigation positioning and timing services. RTK positioning method is used to build a dynamic mobile station relative to the dynamic reference station positioning system. Comparing the advantages and disadvantages of pure inertial navigation and pure GNSS navigation, a combined navigation mode is designed which integrates the advantages of two positioning methods. The software engineering solution is thus designed to observe the solution results in real time by dynamic window, and to test the feasibility and hardware performance of the dynamic positioning system. The hardware design as well as the implementation scheme is developed, together with the navigation data collected and the performance of long time dynamic positioning solution and robust performance of the system tested in open and complex environment and so on. The dynamic positioning system is designed with high positioning accuracy and good robustness, which is suitable for the application of high precision relative alignment of linkage target.
