Abstract: 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.
