Abstract

The invention relates to a positioning system and positioning method of a global navigation satellite system (GNSS) monitoring station. A GNSS reference station is connected with the GNSS monitoring station by a communication link. The positioning method comprises the steps of receiving a first satellite carrier signal of each satellite in a plurality of satellites; determining first ephemeris data and first observation data according to the first satellite carrier signal, determining a first satellite position of each satellite according to the first ephemeris data, and determining a first carrier phase observation value corresponding to the first satellite position according to the first observation data; receiving ephemeris time of each satellite and a differential correction parametercorresponding to the ephemeris in real time by the communication link; and determining a position coordinate of the GNSS monitoring station according to the positions of all first satellites, all first carrier phase observation values and all co-observation satellite correction values. According to the positioning system and the positioning method of the GNSS monitoring station, provided by the invention, the problem that monitoring satellites of the GNSS monitoring station and the GNSS reference station are not synchronous can be solved, and the positioning accuracy of the GNSS monitoring station is improved.

Description

technical field [0001] The invention relates to the technical field of GNSS positioning, in particular to a positioning system and a positioning method of a GNSS monitoring station. Background technique [0002] Based on the global navigation and positioning system (GNSS) to locate the position of the monitoring station, it is widely used to monitor the deformation of bridges, dams, high-rise buildings and other buildings and landslides, so as to make danger warnings based on the deformation and reduce personnel and property losses. [0003] At present, for the position positioning of monitoring stations, a positioning system of monitoring stations includes multiple satellites, at least one monitoring station and at least one reference station. Both monitoring stations and reference stations monitor each satellite to obtain satellite references. The satellite data and the satellite data of the reference station are used to calculate the carrier phase difference and the pseud...
