谈地球自转轴运动和地球空间坐标定位

The earth rotation axis motion and earth space coordinates localization

介绍了天球的基本概念,对比分析了岁差、章动和极移等地球自转轴的运动,着重对几种坐标系相互之间的关系进行了探讨,以实现任意坐标系任意时刻之间的转换,为空间定位奠定了基础。

This paper introduced the basic concept of celestial sphere, comparative analyzed the movement of precession, nutation and polar shift and other earth rotation axis, emphatically discussed the relationship between several coordinate systems, in order to realize the conversion of any coordinate time, laid foundation for spatial localization.
