摘要
A new similar single-difference mathematical model (SS-DM) and its corresponding algorithmare advanced to solve the deformationof monitoring point directly in singleepoch. The method for building theSSDM is introduced in detail, and themain error sources affecting the accu-racy of deformation measurement areanalyzed briefly, and the basic algo-rithm and steps of solving the deform-ation are discussed.In order to validate the correctnessand the accuracy of the similar single-difference model, the test with fivedual frequency receivers is carried outon a slideway which moved in plane inFeb. 2001. In the test,five sessions areobserved. The numerical results oftest data show that the advanced mod-el is correct.

The method for building the SSDM is introduced in detail, and the main error sourcesaffecting the accuracy of deformation measurement are analyzed briefly, and the basic algorithm andsteps of solving the deformation are discussed. In order to validate the correctness and theaccuracy of the similar single-difference model, the test with five dual frequency receivers iscarried out on a slideway which moved in plane in Feb. 2001. In the test, five sessions areobserved. The numerical results of test data show that the advanced model is correct.
