摘要
分析了2000国家重力基本网与1985国家重力基本网重力点的重合情况,详细讨论了确定两网关系的方法:间接平差法、常数转换法和多项式拟合转换法,并给出了两网的关系结果。
This paper analyzes superposition between national gravity datum 2000 and national gravity datum 1985 ,and particularly discusses methods ,that is ,readjustment, constant convert and polynomials, through which the relation can be built in the national gravity datum 2000 and one of 1985. Then,Using the data of the mutual points, the parameter of the relation between 2000 and 1985 are calculated in constant convert and polynomials model.
