Simulation of integrated navigation based on SAR

The techniques of GPS elevation correlation and self-adaptive filtering are employed in the integrated SINS/GPS/TAN/SAR navigation system. The operation principle, algorithm and key techniques are addressed. Technical performance analysis based on computer simulation shows that the SINS/GPS/TAN/SAR integrated navigation system has advantages of high accuracy, wide adaptability and good capability of in-flight alignment. At the same time, this scheme can provide the motion compensation information to SAR. Therefore, on the basis of it, a bidirectional complementary information amalgamation system of navigation devices and task devices can be formed.
