| Abstract: | This paper analyzes the adverse influence of Current Statistical Model on the concrete GPS/DR vehicle integrated localization, and an improved Current Statistical Model used in GPS/DR Integrated localization System information fusion is given, which is based on the principle of Current Statistical Model. The real data tests prove that the system with this algorithm can implement self-adaptation to the system variance without any predetermined parameters, and track precisely the motion state of various vehic... |
