Abstract: | In this paper, It is briefly introduced the principle of satellite position and the error that caused from the satellite signal transmission receiving and SA policy. At the same time, It showed the principle that selected under the several quickly and high accuracy position work pattern and observational station. Final, It listed out the formula that transferred the coordinate of WGS-84 to the Chinese coordinate and the method which worked out the parameter in the formula. |
