Abstract
In order to solve the gross error in space rectangular coordinates conversion between the different coordinate systems, this paper explores the use of robust estimation theory to solve public point coordinate error effect of coordinate transformation. Combined with the specific coordinates conversion example, using Tukey, IGG1 and IGG3 three kinds of power function for the iterative calculation, complete the coordinate conversion. The results show that the robust estimation theory used for space rectangular coordinates between the conversion, can reduce the effect of common point gross error and improve the reliability of transformation.关键词
