【Abstract】 According to the characteristics of high precision GPS deformation monitoring, based on the first period observation results of the monitoring network,and using the carrier phases of the monitoring session as the basic observations, the similar single difference model of solving GPS monitor point deformation information at a single epoch is built.This model avoids the troublesome problem of cycle slip detecting and repairing. It is applicable to both static and dynamic monitoring modes, and suitable for the surroundings that the synchronous satellites are less than four. The correctness of the similar single difference model is verified with the test data.更多还原
