摘要：In this paper, a set of quaternary arc time series of the double phase differences formed by a PS (Permanent Scatter) with its surrounding four PSs in each quadrant are processed together, where the spatial constrains on the parameters are included directly in the adjustment model. Equations of this spatiotemporal analysis model are formulated. A simulation example using this new method is presented. It shows that a priori information of the crustal deformation can be integrated into the integer least squares adjustment model to improve the accuracy of parameters estimated
