摘要
为了分析观测值的时间相关性对GPS基线解算结果及其精度评定的影响,分别利用两条基线的7d观测数据,顾及相关窗口中所有历元的时间相关性,以45min为一个时段将7d观测数据分为224个时段,编制了软件进行基线处理和分析。在忽略和顾及时间相关性两种情况下,采用不同采样率,对224个时段的基线处理结果进行统计分析。
In order to analyze the impact of temporal correlation on the solution of GPS baseline and its accuracy assessment,wedevelop the software to process and analyze the two repeated baselines in the case of considering the temporal correlation of all epcohes in correlation window.Each baseline is computed with 45 miniutes of observations,thereby there are total 224 repeated baselines for the observations of 7 days.We carry out the statistic analysis with 224 repeated baselines in the scenarios of using different sampling rates and considering or neglecting the temporal correlation of observations.
