The Research on Ambiguity Processing of GPS Deformation Monitor

Abstract:

In high accuracy GPS deformation monitor application,we usually use GPS relative positioning, establishing the positioning model with double-difference carrier phase observation to accomplish high accuracy positioning. In accordance with different deformation monitor mode, the processing methods of double-difference ambiguity are accordingly different. In periodical repeated monitor, we usually use routine GPS static relative positioning processing method; in stationary and continuous monitor, we can adopt a DC (direct calculation) method; while in real-time dynamic monitor, we choose a plan of known ambiguity transferring. The paper discusses the ambiguity processing procedures in three different deformation monitor modes, and uses examples proving them.
