最优船位递推滤波算法(二)

Design of Optimal Position Estimator

进一步讨论了天文导航系统动态方程的可观性,介绍了基于天文导航推算最优船位递推滤波方法与传统移线定位方法的关系,并对该方法进行了计算机模拟和实测验证,结果表明:传统的移线定位方法仅是该方法的一个特例,该方法具有精度高、可靠性好、能连续定位、使用方便等优点,是实际可行的。

A more detailed discussion is made of the observability of astro-navigation dynamic system equation and the relationship between the classical running fix and the Kalman filter algorithm based on astro-navigation and dead reckoning. Computer simulation and experimental measurement are carried out to verify the algorithm. The results show that the classical running fix method is only a particular case of this algorithm, and that the algorithm has many advantages such as high precision,good reliability,continuous positioning and easy operation.
