The previous China Gravity Basic Net was established in 1957 (CGBN 57), with its error of 1.5.5 mGal (10-5ms-2) in standard system and 0.0002 in scale. It is now replaced by the new CGBN 85, which comprises 57 gravity stations including 6 absolute gravity stations. The new nation-wide CGBN85, with an average internal accuracy of ±7.8μGal (10-8ms-2) and external accuracy of 20μGal, was then established and has being used in practice. The authors discuss briefly in this paper the key problems arised during...

The absolute gravimeter of second movable laser (type N1M-H) are designed by the National Institute of metrology in 1983. The experimental equipment are presented in the contrast observations of the second international absolute gravimeter at paris in 1985. All research plans are completed in 1987. This paper described the observation results of absolute gravimeter extending about four years in all areas of China. Especially in Xiangshan Seismic Station, in order to study the microgravity variation, four points of absolute gravimeter were set up. The observation study of virtical gradient, harizontal variation and its variation with time are given. From geophysical surveys, national defence and other departments, absolute gravity data have accumulated in many years. For the nontidal gravity research, these fundational observations have important significance.
