Beschreibung
Zusammenfassung:	The invention relates to the deformation monitoring technology, thereby solving a problem of low accuracy of the reference point calibration mode of the existing deformation monitoring. The inventionprovides a reference point checking system and method for GNSS deformation monitoring. The system comprises a satellite, a deformation monitoring system, a GNSS reference station, and a GNSS continuous operation reference station. The deformation monitoring system acquires observation data and three-dimensional coordinates of the GNSS continuous operation reference station; observation data of anyGNSS reference station are calculated to obtain three-dimensional coordinates of the GNSS reference station; and current three-dimensional coordinates of the GNSS reference station are replaced by the three-dimensional coordinates, obtained by the current solution, of the GNSS reference station. The reference point checking system and method have the following beneficial effects that: a problem that the optical instrument
