- But due to its limited coverage, inter-satellite link is the future emphasis in the feild of low earth orbit satellite. 低轨道卫星是卫星通信的发展趋势,但单星覆盖范围小决定了星间链路技术是将来发展的重点。
- Alternatively, if the star were small, the life-supporting planet would have to have a close orbit round it and also provide the perfect conditions for life forms to develop. 反之,如果恒星很小,维持生命的行星就要在离恒星很近的轨道上运行,而且要有极好的条件才能使生命得以发展
- Development and applications of gravimetry and satellite-borne gravimetry are reviewed. Relations among the rectangle coordinates, Keplerian elements, Hillian elements and Equinoctial elements to describe the motion of low earth orbit satellite are given. 回顾了重力测量和卫星重力探测技术的发展和应用,阐述了描述低轨卫星状态的直角坐标、Kepler根数、Hill根数和Equinoctial根数之间的相互关系,认为Hill根数和Equinoctial根数能够避免由卫星轨道奇异带来的计算问题,分析了低轨卫星的受摄运动,给出了摄动模型。
- The design results of the example constellation show that the self-stabilization design is effective to enhance the configuration stability of the elliptical orbit satellite constellation. 对实例星座的设计结果表明,自稳定设计方法对提高椭圆轨道星座的构型稳定性是有效的。

- By using the closed orbit theory, the photodetachment cross section of H- near a metal surface is derived and calculated. 利用闭合轨道理论,我们推导和计算了H-在金属面附近的光剥离截面。
- Highly Elliptical Orbit Satellite 高椭圆轨道卫星

- Withthe enhancement of the space militarization, it is necessary to know the present low earth orbit satellites. 随着太空军事化趋势的日益增强,了解和认识当前的低轨道卫星较为必要。
- Unlike the case of the photodetachment of H- near an elastic interface, the length of the closed orbit does not equal the twice distance between the ion and the surface. 傅立叶变换截面中的每一条共振峰正好和电子的一条闭合轨道相对应。
- The coordinate of the GEO(Geostationary Earth Orbits) satellite is important in the algorithm of Beidou passive timing. 摘要 GEO卫星的坐标是北斗无源授时解算过程中一项重要的参数。
- The period, action, and length of the detached electron’s closed orbit are nearly the same as the case of the photodetachment of H- near an elastic interface. 因此可以用弹性截面模拟金属面。
