Problems solved by technology
Specifically, the single-difference method solves the receiver observation data, due to the existence of wide-lane UPD, compared with the double-difference method to solve the receiver observation data, it takes longer to fix the ambiguity
Compared with the single-difference method to solve the receiver observation data, the double-difference method takes less time to determine the fixed ambiguity, but the accuracy of the relative positioning altitude angle is poor.

The invention discloses a GNSS deformation monitoring system. The system comprises one or more first data receiving modules, one or more second data receiving modules, a decoding module, a data selection module and a processing module, the first data receiving modules and the second data receiving modules acquire first receiving data and second receiving data respectively, then the first receivingdata and the second receiving data are decoded into first input data and second input data by the decoding module decodes respectively, and the data selection module groups the second input data, andthe processing module conducts calculation and acquires an optimal solution by adopting a method which combines a single-difference mode with a double-difference mode. According to the GNSS deformation monitoring system, the method which combines the single-difference mode with the double-difference mode is adopted for calculating observation data of a receiver, and the solution precision of thedeformation amount of detection points can be improved.
Description
technical field [0001] The invention relates to the technical field of satellite positioning and navigation, in particular to a GNSS deformation monitoring system. Background technique [0002] With the development of the global satellite positioning system, satellite navigation and positioning technology has been widely used in military, transportation, surveying and mapping, communication, time comparison, atmospheric research and other aspects. [0003] Due to the use of the Global Navigation Satellite System (English full name: Global Navigation Satellite System, English abbreviation: GNSS) positioning technology, the observation is not limited by weather conditions, there is no need to maintain communication between stations, and the three-dimensional displacement and automation of points can be measured at the same time Therefore, it is not only widely used in large-scale and long-distance monitoring projects such as plate movement, sea level change, and local crustal ...
