摘要
Abstract
The main filters tend to diverge when three heterogeneous sensors of the traditional INS/ CNS/GNSS integrated navigation system makes information fusion, so a new INS/CNS/GNSS integrated navigation system is designed, in which filter 1 is composed of inertia navigation and satellite navigation and filter 2 is composed of inertia navigation and chronometer navigation. The position and attitude integrated method is proposed, and the measuring matrix is deduced. The simulations prove that the effective consistence of precision and reliability are realized by adopting this method and that the precision of position, velocity and attitude is better and the filter is comparatively stable.关键词
