天球坐标

Based on satellite ephemeris and time data of the satellite coordinates of the celestial coordinate system.

详细说明：根据卫星星历和时间数据计算卫星在天球坐标系中的坐标。

It is the study of the use of spherical coordinates to determine how the objects projected on the celestial sphere depending on the location, and study these changes depending on location laws and causes, offered to time depending on location of celestial calculation of parameters of the basis and method, as all the astronomical observations necessary for the basics, the main means of spherical trigonometry math and matrix operations.

它所研究的是怎样利用球面坐标确定天体投影在天球上的视位置，并研究这些视位置变化的规律和产生原因，提出以时间为参数的计算天体视位置的依据和方法，成为一切天文观测所必需的基础知识，主要的数学手段是球面三角学和矩阵运算。

Based on IAU2000 resolutions,the related matters of the coordinate transformation between CRS and TRS is studied.

基于IAU2000的有关决议，重新研究了CRS和TRS之间转换的有关问题，主要内容包括：天球历书极目前存在的问题和天球中间极的引入；非旋转原点、天球历书原点和地球历书原点的基本概念；基于春分点和NRO的坐标转换模型以及其中的有关参数的确定。

Latin:"Balance", in astronomy, zodiacal constellation lying between Scorpius and Virgo, at about 15 hours 30 minutes right ascension (the coordinate on the celestial sphere analogous to longitude on the Earth) and 15° south declination (angular distance south of the celestial equator).

从天文学上说，天秤座，黄道星座，位于天蝎座和处女座之间，约位于赤经15时30分（类似于地球经度的一种天球坐标），南赤纬15度。
