稳健估计下的光学经纬仪多站交会算法
Multi-station intersection algorithm of optical theodolites based on robust estimation
摘要
Abstract
In order to improve the reliability of the test of air and ground explosion point coordinate in shooting range,and reduce or eliminate the influence of gross error effectively,the multi-station in-tersection algorithm of robust estimation was proposed.Firstly,the principle of traditional least square multi-station intersection was introduced.Then,the principle of robust estimation method and the calculation method of internal and external reliability index were introduced.Finally,the correct-ness of the algorithm was verified and the internal and external reliability index was calculated by a simulation example.The results show that the minimum gross error which can be detected is between 0.054~0.066 degrees through the adjustment model.The gross error of observation value has 2.6~4 times more effect on the parameter vector than root mean square error.When the gross error exists, the accuracy of the robust estimation method is better than that of the traditional method,and the ro-bust estimation method can reduce the influence of gross error on the adjustment results effectively and play a positive role in improving the accuracy of coordinate measurement of the burst point.关键词
