| 摘 要： | 应用线性回归、符号检验等数理统计方法研究了１９９３年完成的跨青藏高原首期ＧＰＳ网３９条基线的数据处理结果。通过对单基线观测中误差、重复观测基线互差及异步环闭合差的精度分析，认为由１６个观测点组成的跨青藏高原ＧＰＳ监测网的基线平均相对精度达０．１ｐｐｍ。

| Abstract: | Using the statistical approaches such as the least square regression and sign test,the results processed from the 39 baseline across the Qinshai-Tibet plateau,they were observed first by GPS in 1993,are analyzed.The analysis of the root-mean-square scatters of single-session baseline measurement and their differences as well as the so-called closure of asychronously baseline ring indicates that the relative positioning precision on an average of first measurement-derived Qinghai-Tibet GPS network consisting of 16 geodetic sites,reaches to 0.1 ppm. |
