摘要
The integrated navigation system, specially the system based on GPS and INS, is a leading trend of navigation technology, and some of typical integrated navigation systems have been developed and tested in the past few years[FAR,98]. But due to the complex application circumstance, it is difficult to describe the noise statistical property accurately. In this paper, a modified adaptive filter algorithm is presented for INS/GPS Integrated Navigation system. At first, a improved Kalman filter and H-infinity robust filter are explicitly represented for INS/GPS Integrated Navigation system. Meanwhile, an standard for judging that whether the filter trends to divergence is proposed to combine the two methods. Aiming at the detail position/velocity integrated mode, the computer simulation result of INS/GPS integrated navigation show that this method can restrain the divergence effectively and has better adaptive ability. http://ieeexplore.ieee.org/stamp/stamp.jsp?arnumber=4281733
