| Abstract: | It is found that when conventional methods,such as Trigonometric Interpolation,are used for standardization of GPS satellite orbits, and the order of interpolation or fitting increases,the accuracy will decrease.Thus,a conception of moving intervals is proposed solving this problem.The results from computing and analyzing the precise ephemeris supplied by National Geodetic Survey of U.S.as an example show that this standardization method based on the moving intervals can solve the problem on accuracy decrea... |
