Abstract:

In this paper the international connection measurement of gravity datum points at Antarctic Great Wall station ( p= 62°12.19s, λ=58°57.18w) by using Lacoste - Romberg gravimeters G and the network layout of gravity and deformation monitoring stations in Fielders region of Antarctics and its observation are presented. Values of gravity datum points and accuracy obtained at Great Wall Station are 982208.682 and ±0.021 mgal respectively. The gravity network of polar area is composed of 18 gravity points. Its control area is about 40 square kilometers. Average measuring section accuracy of the network is ±0.029 mgal. Accuracy analysis for observation results under the condition of different transportation is carried out.
