A method and system for monitoring the displacement of a CORS reference station

Abstract

The invention relates to the technical field of the Beidou satellite global positioning system, and discloses a method for monitoring the displacement of a CORS reference station, which includes: selecting the first reference station with the first distance from the reference station to be detected; selecting the first reference station with the second distance from the first reference station; The reference VRS grid point of the distance, the reference VRS grid point contains the weight of the base station to be detected; the calculated position of the first base station is obtained by calculating the original observation amount of the first base station and the original observation amount of the reference VRS grid point , and compare the calculated position of the first reference station with the measured position of the first reference station to obtain the displacement; judge whether the reference station to be detected has displaced according to the displacement, and update the position coordinates of the reference station to be detected in real time if displacement occurs. It can accurately and real-time monitor the displacement of the reference station in the seismic zone and the place where the crustal movement changes greatly, and update the coordinates of the reference station in real time, making the service accuracy of the national CORS network reliable and improving the user experience.

Description

technical field [0001] The invention relates to the technical field of the Beidou satellite global positioning system, and discloses a displacement monitoring method and system of a CORS reference station. Background technique [0002] With the continuous development and popularization of satellite positioning technology and IT technology, the construction and development of the national CORS network needs to be higher and higher. It is also necessary to deploy reference stations and operate high-precision positioning services in earthquake zones and places with large changes in crustal movement. [0003] This requires regular inspections of the reference stations that meet the requirements of station building, so as to quickly find out whether there is any abnormality in the station, so as to ensure the quality of service and improve the stability, accuracy and reliability of CORS services. Most of the existing patents focus on GNSS data quality detection or detection and a...

AI Technical Summary

Problems solved by technology

Most of the existing patents focus on GNSS data quality detection or detection and alarm of mobile CORS reference stations, etc. Generally, reference stations in normal areas will not shift, but reference stations in special areas such as seismic zones and places with large crustal movement The station may be displaced and other situations may cause CORS reference station system service problems
