Improved Algorithm Based on Dempster-Shafer Theory: Using in the Integrated Navigation

The algorithm of multi-sensors´ information fusion is studied here based on Dempster-Shafer theory. An improved approach for Dempster-Shafer theory can be put forward. We should use this theory in the integrated navigation. The whole reliability is imported in the whole system and we can analyse it during the calculating process. Because of that we can estimate whether the GPS´s signals are interfered and analyse these data. So we should choose the better navigation´s mode at the right time and advance the precision of the whole system.
