| 摘 要： | 讨论低椭圆轨道移动卫星通信系统的星座设计问题，提出了星座中各卫星高度不断变化时，卫星群相位的优化设计方法。本文设计的覆盖我国的低椭圆轨道系统星座有二个方案：第一个方案是由１２颗低椭圆轨道卫星（远地点为２９０６ｋｍ而近地点为４２７ｋｍ）组成；第二个方案为弥补系统对低纬度地区覆盖率低的缺陷，而增加四颗赤道平面中轨道卫星，提供对我目的连续覆盖。 |

| Abstract: | The problem in the constellation design of low elliptical orbits of the mobile sat-ellite communication system is discussed.An optimum method for the selection of phase of satel-lite constellation is suggested due to various the height of satellites in orbits. Adopting the con-stellation of the low elliptical orbit system for covering China has two schemes.The rirst schemeis:The constellation consists of 12 satellites with the low elliptical orbits(apogee at 2906 km,perigee at 427km). The second is:Adding 4 satellites with the mid earth orbit on equatorialplane to compensate the drawback due to low coverage rate at low latitude in first system. Thesecond scheme can provide continuous coverage of China. |
