Abstract

The present invention relates to a vibration processing and alarm method of a mobile CORS base station. According to the method, a vibration sensor is installed on a CORS antenna base, and a CORS antenna phase center offset is monitored. The working state of a mobile CORS is judged through an offset threshold, the quality of positioning server is ensured so as to ensure the positioning server precision of the CORS base station.

Description

technical field [0001] The invention belongs to the technical field of Beidou satellite global positioning system, and in particular relates to a ground CORS base station, especially a mobile CORS base station, which is used to avoid or reduce the influence of base station vibration on positioning accuracy. Background technique [0002] The ground CORS base station is a means to improve the measurement accuracy of the Beidou satellite global positioning system. The existing ground CORS base station is generally fixed, and in most cases it is not necessary to consider the influence of the vibration of the base station itself. However, in some special cases, such as disasters or emergency response, when the original fixed ground CORS base station is damaged or the coverage of the original base station is not enough, it is necessary to quickly establish a new ground CORS base station by deploying mobile CORS base stations. Realize high-precision positioning services. However, ...
