Analysis of BDS/GPS Integrated Kinematic Difference Positioning Algorithm in Multi-Occlusion Environment
Abstract The integrated BDS/GPS kinematic differential positioning algorithm is studied, and we analyze the benefit of the BDS signals on the ambiguity resolution. Experiments are conducted based on the kinematic measurements collected from the regions with serious signal occlusion. Test results show that BDS/GPS integration increases the number of the visible satellites, strengthens of the geometric structure and improves the success rate and reliability of ambiguity resolution. In addition, the positioning accuracy is 8 mm with the GPS/BDS integration in the horizontal direction, and 16 mm in the vertical direction. For GPS alone, the positioning accuracy is 3 cm and 8 cm, respectively.
