Study on the Coversion Method of Spacial Rectangular Coordinate to Geodetic Coordinate Based on Intermediate Variables
摘要
Abstract
Using iterative method to realize the conversion of spacial rectangular coordinate to the geodetic coordinate,although the accuracy is higher,but the operation is complex and the efficiency is low.In order to improve the accuracy and operation efficiency of coordinate transformation,a new conversion method of spacial rectangular coordinate to the geodetic coordinate is put forward.The coordinate transformation is reahzed only with several intermediate variables,and the calculation process is simple,the result is accurate.The measured data of the satellite receiver is used to validate algorithm.Finally,by comparing with the iterative method,the accuracy assessment is carried out.The results show that the conversion accuracy of the method is higher two orders of magnitude than iterative method at latitude and longitude,and is higher 0.2 meters at height.关键词
