LATEST ABSOLUTE GRAVITY MEASUREMENT AT SOME POINTS OF 2000 NATIONAL BASIC GRAVITY NETWORK
摘要
Abstract
To analyze the long - term stability of some points of 2000 National Basic Gravity Network, the absolute gravimeter, FG5/240, was applied to the absolute gravity measurement for two benchmark points of 2000 National Basic Gravity Network, which are located in the Yongxing island and at Zhengzhou station, and the observation accuracy was proved to be better than 5×10-8ms-2. As a result, the differences between the observation values and the reference values at the two points of 2000 National Basic Gravity Network are obtained.关键词
