CG-5重力仪在海南岛陆流动观测的零漂特征
The Drift Characteristics of CG-5 Gravimete in the Flow Observation of Hainan Island
摘要
Abstract
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.关键词
