查询词典 geostationary

This paper presents a new algorithm to calculate control parameters for west-east station keeping for dual-spin geostationary satellites.With the same accuracy provided by traditional ways,it is simpler and easier to understand.Also,the relationship between orbit control efficiency,rotation speed and width of engine impulse is explored.

0引言地球同步自旋卫星由于其技术成熟、运行稳定，在航天领域保持着强大的生命力，尤其是在气象卫星的运用上，它的自旋特性可大大降低有效载荷的复杂性并相应延长其寿命，因此我国在轨的风云二号气象卫星和欧洲2002年发射的第二代气象卫星都采用自旋平台。
