Multi-antenna ultrashort base line positioning monitoring method and device and storage medium

Abstract

The invention provides a multi-antenna ultrashort base line positioning monitoring method and device and a storage medium. The method comprises the steps of receiving a satellite signal by a pluralityof receivers arranged in advance, taking arbitrary one of receivers as a reference station, obtaining original observation data of the reference station, and calculating to obtain carrier phase differential correction and pseudo-range differential correction according to an accurate position of the reference station in the original observation data; obtaining antenna coordinate of each receiver according to the differential correction and antenna position observation data of each receiver; rapidly switching the reference station to obtain relative positions among receivers to achieve the purpose of mutual monitoring; and positioning a target point according to the antenna location position of each receiver. The plurality of receivers are arranged in different directions, the carrier phasedifferential correction is obtained according to the positioning information of the reference station, antenna coordinate of the plurality of receivers is determined, so that the target point is positioned and monitored, the monitoring range is relatively large, and monitoring information collection and processing is convenient.

Description

technical field [0001] The invention mainly relates to the technical field of satellite positioning processing, in particular to a multi-antenna ultra-short baseline positioning monitoring method, device and storage medium. Background technique [0002] At present, most deformation monitoring devices use post-event differential analysis or single-antenna RTK solution. Using post-event differential analysis can use the error information released by IGS. Although it can improve some error corrections, it usually requires a long waiting time. Decomposition calculation or single-antenna RTK solution is not conducive to real-time monitoring of deformation. It is difficult to meet real-time performance for geological deformation disasters such as landslides, and the area that can be monitored by post-difference calculation is small, which can only be used for the antenna location or Monitoring is carried out in a small area, which is not convenient for monitoring information colle...
