Processing of the static data observed by CG-5 gravimeter via Tsoft

摘要

CG-5 gravimeter from Scintrex Limited Canada is a new kind of digital gravimeter with the quartz spring as its sensitive element. In this paper, a set of static data observed by CG-5 gravimeter is processed through Tsoft, a software programmed by Royal Observatory of Belgium for tidal gravity data pre-processing, which uses strong capability of computer for graphic processing and friendly man-machine interface. Some major static performance criteria, such as long-term drift rate, day fluctuations in residuals, data noise, etc, are obtained and also compared to those observed by other tidal gravimeters presented in other papers. Based on current observation precision and function, with the help of the software Tsoft for tidal data pre-processing, CG-5 gravimeter can be used as a temporary equipment in the gravity observation station for monitoring crustal deformation, earthquakes and groundwater changes. Also, it contributes to research the impact of large-scale construction projects on the environment.
