地球坐标系 earth coordinate system
[天] terrestrial coordinate system
- 推导了协议地球坐标系下的卫星运动方程。
The equation of satellite orbital motion was derived in the conventional terrestrial coordinate system. - 因此,这种以新大地坐标表述点位的新型大地坐标系,不仅可用于简化地球椭球面上的计算,更可用于三维G IS建模。
Accordingly, it is concluded that the new form of geodetic coordinate system can be adopted not only in geodetic computation, but also in modeling of GIS. - 卫星精密定轨中,需要计算天球坐标系(CRF)到地球固联坐标系(TRF)之间的转换。
For precise satellite orbit determination, the transformation should be done between the Celestial Reference Frame(CRF) and the Terrestrial Reference Frame(TRF).
