Design on Configuration Schemes of Satellite/Pseudolite Integrated Navigation System

The positioning accuracy of satellite/pseudolite integrated navigation system has close relationship with the geometric configuration of the pseudolites. The layout of the pseudolites on the aircraft carrier is studied in order to improve the positioning accuracy of the system. First, eight points are selected that can be distributed on the aircraft carrier according to the characteristics of the pseudolites and aircraft structure. Then, the simulation model of carrier landing process is built and the flight paths of carrier and aircraft are constructed. At the same time, the ship motion model is introduced into the simulation model in order to be close to the real environment. Finally, the configuration scheme of the pseudolites on the aircraft carrier is proposed after the analysis of the influence of the pseudolites on the positioning accuracy by using the dilution of precision. The results show that the proposed scheme can reduce the dilution of precision, especially the vertical dilution of precision, and improve the positioning accuracy.
