The history and several technical characteristics of FG5 absolute gravimeter are reported, and some data of FG5/112 absolate gravimeter measured in China are given.
This paper introduces the absolute gravity determinations carried out by the Institute of Geodesy and Geophysics, Chinese Academy of Sciences using the FG5 absolute gravitmeter at 26 fundamental stations of the Chinese Crustal Movement Observation Network.
The history,design feature and its determination of gravity and correction for FG5 absolute gravity meter are introduced. The absolute gravity at the location of 3053 station is surveyed, and the survey data is proced and the result is aralyzed.
In this paper, the present development state of absolute gravimeter is introduced. The improvement opinions of FG5 absolute gravimeter are presented, and thus the measurement precision of FG5 gravimeter will be rise.
