我们提出了一个系统的和统一的治疗地球自转从大地测量,天文学和地球物理的角度来看。岁差章动和极移的精确术语对于理解导致地球自转不规则性的相互作用的物理现象是非常重要的。总的来说,赤道平面的四个极点被定义为描述地球自转。地球方位参数的各个组成部分,即,岁差章动、极移和世界时(或一天的长度)。本文展示了如何很长的基线干涉测量和环形激光不同的地球自转方面,并提出了目前国家的最先进的测量精度,可以实现。
We present a systematic and unified treatment of Earth rotation from the geodetic, astronomical, and geophysical point of view. A precise terminology of precession-nutation and polar motion is of great importance for understanding the interacting physical phenomena leading to rotational irregularities of the Earth. In total, four poles of the equatorial plane are defined for the description of Earth rotation. The various components of the Earth Orientation Parameters, i.e., precession-nutation, polar motion, and universal time (or length of day) are summarized. This paper shows how very long baseline interferometry and ring laser differ in terms of Earth rotation and presents the current state-of-the-art measurement accuracy that can be achieved.
