摘要
收集整理2010以来海南岛陆流动重力测量数据,获得了使用CG-5重力仪进行流动重力测量期间,每台仪器的日均零漂率,并对测量数据进行拟稳平差处理后获得每期测量数据的平均点值精度。通过研究,认为CG-5重力仪在海南岛陆测量期间的日均零漂率不存在随着测点纬度的增加而减小的情况;每期观测数据的平均点值精度和两台仪器日均零漂率标准差均值呈正相关关系。
This paper analyses the mobile gravity data of Hainan Island since 2010, and gets each CG-5 Gravimete ＇s zero drift rate per day during measuring and the averaged-solution accuracy of each period by quasi-stable adjustment processing the measurement data. The results show that the CG-5 Gravimete ＇s zero drift does not decreace as the latitude of the measuring point increases during measured in Hainan Island, and the relationship is positive correlation between Gravimete ＇s zero drift of each observation data and the daily zero drif standard deviation of per instrument.
