Abstract:
In view of the serious signal occlusion and the small number of GPS visible satellites in the actual GNSS crustal deformation rover monitoring, the BDS/GPS dual system observation was adopted, and the improvement of the precise single point positioning performance of BDS/GPS in the actual rover observation was analyzed. Based on the observation data of the GNSS crustal deformation monitoring network in Shimian area of Sichuan, the number of visible satellites, GDOP value, and the positioning accuracy and epoch utilization of the three positioning modes of BDS, GPS and BDS/GPS in the actual observation environment and the simulated worse observation environment were analyzed. The results show that BDS/GPS can greatly increase the number of visible satellites, reduce the GDOP value, significantly improve the satellite spatial geometry, and improve the convergence speed and positioning accuracy in mountainous areas with poor observation environment; compared with BDS and GPS, the convergence speed can be increased by 50%-80%, and the positioning accuracy can be increased by 20%-50%; the positioning accuracy of a single system is greatly affected by the altitude angle, and the BDS/GPS can still maintain high accuracy and stability at higher altitude angles; in heavily shaded areas, in order to ensure sufficient dual-frequency observations, the number of observation satellites must reach 6 or more. With its high stability and high precision, BDS/GPS is more conducive to capturing the weak displacement signals of crustal deformation and earthquakes in areas with severe terrain fluctuations, and has good application in complex observation environments(mountains, forests, and densely built areas).
