摘要
Abstract
The main factor in determining the computation time of Kalman filter is the dimension n of the model state vector. The number of computations per iteration is on the order of n3. Any reduction in the number of states will significantly decrease the computation time. This paper introduces a full-order INS/GNSS/SAR integrated navigation system, and its reduced-order model. The simulational resuits prove that this integrated navigation system is of high performance and its reduced-order model can also provide satisfactory accuracy for aircraft navigation.关键词
