| 摘 要： | 文1]和2]中提出根据拟合后剩余残差的统计检验来全面评估解算,其想法是除了一般采用的ＲＭＳ和协方差外还试图以更多的统计量来反映解算更细致的差别.将其应用于Ｌａｇｅｏｓ激光资料的处理,文3]鉴别了具有相同ＲＭＳ水平而差异较大的不同解算.但是除了理论上的依据外,文3]事实上未能表明其中残差分布较合理的解确实优于其余的情况.本文的目的之一是试图改进这一不足之处.采用由美国喷气推进实验室(ＪＰＬ)发展的ＧＰＳ数据处理软件ＧＩＰＳＹ,本文比较仅固定精密星历(ＦｉｘｅｄＰｒｅｃｉｓｅＯｒｂｉｔｓ,简称为ＦＰＯ)和同时固定精…

| Abstract: | The statistical tests of the post-fit residuals are applied to the regional GPS reduction. The strategies of fixed-precise-orbits and precise-point-positioning are compared.It is shown that in the former case, conceivable signals, still remain in the post-fit redsiduals while in the latter case they are mainly noises. Based on the differences between our solutions with ITRF96 and the repeatabilities of the solutions, it is concluded that the stragegy with reasonable post-fit residual statistics is better than others, Statistical tests of the post-fit residuals present another evidence that besides accuracy and computation saving, PPP is more preferable than fixed-precise-orbits in the regional GPS analysis. |
