| Abstract: | This paper introduces the theory and method of error rectification in INS/SAR integrated navigation system. How to obtain the observations and how to construct the INS/SAR integrated filter are described. The simulation results prove that the error rectification method can greatly improve the navigation accuracy and it has the strong capability of initial acquisition and alignment. |
