Abstract

The invention discloses a method for processing high-precision displacement deformation monitoring data based on the Big Dipper. The method is used for processing integer ambiguity parameter data obtained in the process of geological displacement deformation monitoring and high-precision positioning carried out based on a Beidou satellite navigation system and a GPS navigation system. The method includes the steps that (1) a GPS and Beidou combined receiver is arranged in a displacement deformation monitoring center service station; (2) the GPS and Beidou combined receiver obtains an output pseudo-range of each observation epoch, a carrier phase observation value and a satellite ephemeris parameter, and the preceding data are transmitted to a data processing center system; (3) the data processing center system calculates an integer ambiguity parameter by means of a carrier phase difference equation. According to the method, the high-precision integer ambiguity parameter can be obtained, and a good monitoring effect can be obtained when the Beidou satellite navigation system is applied to geological displacement deformation monitoring.

Description

technical field [0001] The invention belongs to the technical field of real-time monitoring of geological displacement and deformation based on a satellite navigation system, and in particular relates to a method for processing high-precision displacement and deformation monitoring data based on Beidou. Background technique [0002] Water conservancy projects, large buildings, mines, bridges, etc. are the basic structure of the national economy. As an important connection of national power, transportation network, and energy supply, they play a role that cannot be ignored in economic construction. Due to normal and abnormal loads, many water conservancy projects, bridges or mining areas, and geology have been deformed or damaged to varying degrees. Therefore, the health monitoring of water conservancy projects, bridges, and mining areas has become an important part of the normal operation and operation of water conservancy, bridges, and mines. The main tasks of the managemen...
