摘要
编制了在ＧｉｖｅｎｓＧｅｎｔｌｅｍｅｎ正交变换算法下的多级复弧协方差分析软件．运用到引力常数ＧＭ解算的情形中，并计算了未参加估计的台站坐标的误差对产生解算结果的影响．这种影响的直接后果是降低了解算的精度．
On the basis of the Givens Gentleman algorithm of covariance analysis, a program to deal with real data is coded in this paper. When the program is applied to the GM solution obtained in , the errors of the station coordinates are taken into consideration. The real sigmas are shown to be larger than the computed ones, and this means a degradation of accuracy. The explanation for and implication of the result are discussed preliminarily.
