ON THE ACCURACY AND SYSTEM TRANSFORNATION OF THE PREVIOUS CHINA GRAVITY BASIC NET 1957

Jiang Zhiheng Research Institute of Surveying and Mapping Beitaipinlu 16,Beijing,P.R.China  
After a brief review of history and technical keys of the previous China Gravity Basic Net(Net57),the author discusses the various errors in Net57 and their sources,also the mathematical model for transformation between the previous and present systems.The result shows that,the rela- tive measurement accuracy is about±0.06 mgal with an error of.00016 in scale of instruments used.A basic error of-13.56 mgal and a scale error of.00019 as well as unlinear error of 0.1-0.2 mgal were found in the Net57 gravity values.It is possible to transform the previous Net57 into the new system with an accuracy of±0.05 mgal which can he ignored compared to the measurement errors.
