1.Abstract: All orbits by which targets can be covered are described according to the longitude of ascending node.
文摘:以升交点经度的范围来描述所有能覆盖到目标的轨道。收藏指正
2.In this paper, the impacts of 4 types of LEO orbit parameters—argument of latitude(AOL), right ascension of ascending node(RAAN), orbit height and inclination—on the distribution and number of occultation events a single LEO satellite observed are discussed through simulation and some conclusions are drawn.
分析了对于单颗LEO卫星,掩星事件的分布和数量随着LEO轨道参数包括轨道升交角距、升交点赤经、轨道高度和倾角而变化的规律,并得出了相应结论。收藏指正
3.This paper discusses in detail the range of lon gitude of ascending node of the orbits, by which point and area targets can be c o vered in different conditions by considering the disturbance of the earth shape J2 using a sphere triangle method, and provides a whole analytic expressio n.
利用球面三角方法详细讨论了在考虑地球形状J2项的摄动影响时,各种情况下能覆盖目标点的轨道的升交点经度范围,并将其推广到对区域目标的覆盖,给出了完整的解析表达式。收藏指正
4.In view of the regression characteristic and the configuration maintenance demand of the regional coverage satellite constellation, the constellation configuration is optimized using the linear relations between the semi-major axis and inclination and the rates of change of the ascending node right ascension and phase, which enhance the long-term stability of the satellite constellation configuration, simultaneously the sub-stellar and the phase are controlled through changing the deviations of the semi-major axis and the inclination.
摘要针对区域覆盖卫星星座的回归特性和构型维持需求,利用轨道半长轴和倾角与升交点赤经漂移和相位角漂移变化率之间的线性关系来优化星座构型参数,提高卫星星座构型的长期稳定性,同时通过协同控制轨道半长轴和倾角漂移量来实现区域覆盖星座构型维持。收藏指正
5.And then sort the child nodes of each node in the ascending order using IComparer interface.
