| Abstract: | A method of kinematic deformation surveying by single epoch is described here to obtain the large deformation.At first, we use the wide-lane measurements and the approximate coordinates of monitor sites to resolve the initial wide-lane ambiguities.Based on the correlations between the ambiguities, the ARCE method is used to search the correct wide-lane ambiguities.A rough deformation is obtained.Then, we use the L1 measurement and the method of without cycle slip detection and ambiguity resolution to obtain the residual deformation.The tolerance of position error for a priori coordinates is increased to 70 cm,which is suitable for kinematic deformation surveying. |
