抗差 M 估计在 GPS/北斗双系统定位中的应用
The Application of Robust M Estimation on Positioning of GPS and Compass Dual System
摘要
Abstract
Arming at the problem of that the classical least squares estimation has no re‐sistance to the gross error ,the basic principle of robust M estimation with robust ability was discussed in this paper .T he three commonly robust M estimations and the classical least squares estimation were tested using GPS and Compass observed data .According to the re‐sults ,the robust effect and efficiency were analyzed and compared with Code pseudo range in the relative positioning of the GPS and Compass dual system .It showed that the results of the robust M estimation is more close to the true value than that of the least square method ;In the three commonly robust M estimation ,the IGG‐Ⅲ’s robust effect and efficiency were better than Huber and Danish method .And the IGG‐Ⅲ was easily achievable .关键词
