摘要
文中分析天文经纬度归心公式中各变量的特点,推导基于2000国家大地坐标系统简单实用的归心计算公式,进一步给出由已确定变量推求归心元素测量精度的数学关系式。验证实用公式计算的归心改正数满足专用工程天文经纬度的计算精度需求。
According to the actual needs of engineering survey ,it analyzes the character of variables in the formula on astronomic longitude and latitude reducing to center ,deduces a simplified formula of reducing to center on CGCS2000 ,and then gives the mathematical relationship between the variables for elements of centring measurement accuracy .And it proves that the precision of simplified formula can fit the actual needs .
