satellite earth observation

With the development of micro-satellite and the need of Earth observation mission or space docking mission, we need to control the satellite precisely.

随着微小型卫星的发展，以及我国对地观测和空间对接的需要，我们需要卫星对姿态进行高精度的控制。

This paper describes the understanding on earth observation satellite ground segment mission control system.

阐述了对地观测卫星地面管理控制系统的认知和理解.

The attitude control system of the earth observation satellite is a complicate, high accurate, long-life and earth-oriented three axis stable system with the solar panels orienting the sun in the sun synchronous orbit.

地球观测卫星姿态控制系统是个复杂的，高精度，长寿命对地三轴稳定，在太阳同步轨道上帆板对太阳定向的系统。

To reduce the debugging cycle of ground operation control system and space satellite system, and carry on the simulation test and the technical confirmation to the satellite navigation system quantitatively, it is imperative to build an earth station observation simulation system.

为了缩短地面运控系统与空间卫星系统的调试周期，定量的对卫星导航系统进行仿真测试和技术验证，建立地面站观测数据仿真系统势在必行。

Satellite imagery, captured by the high-definition earth observation satellite "Gaofen-1," shows a 22-meter-long, 13-meter-wide object in the southern Indian Ocean according to the State Administration of Science, Technology and Industry for National Defense.

据国防科工局消息，高分辨率地球观测卫星“高分一号”拍摄到的卫星图像中，在南印度洋海域观测到长约22米，宽约13米的疑似漂浮物。
