Abstract: Both GPS observations and errors have some speciality and complexity. After analyzing characteristics of study on reliability of GPS network, the target of inside and outside reliability of GPS network was deduced, a new reliability theory and outlier analysis method was established based on the correlative analysis theory. The targets of GPS network’s reliability were analyzed and the influence vectors Fi was taken as one of these. As a parameter, the correlative coefficient between Fi and the residual vector V can snoop and remove the outliers. This theory has a good application in correlative observation with multi-outliers analysis.
