摘要： An elliptical orbit satellite system which describes communication and TT&C with ground stations. Earth stations are located for the circular orbiting satellite in a way such that the line of sight can never include geo synchronous satellites. The ground stations for the elliptically orbiting satellites monitor the position of the satellite, and no antenna communicates with a satellite which is in direct line of sight between the antenna and a geo satellite. Another aspect of the invention locates two TT&C stations, separated in longitude by 90.degree. and configures these stations such that each satellite in each constellation will be able to communicate with one of the two TT&C stations once during each satellite rotation period.

摘要： A special set of elliptical satellite orbits are described which allow preferential coverage of one parameter over another. According to a first modification, the orbits are retrograde, and preferentially cover one geographical location or time of day as compared with another. A second modification uses prograde orbits and allows the apogee of the orbit to be offset a constant amount with respect to the sun, to thereby cover a different time of day relative to the others. According to a special preferred mode of the invention, the apogee is always pointing towards the sun.
摘要翻译：描述了一组特殊的椭圆卫星轨道，其允许优先覆盖另一个参数。根据第一修改，轨道是逆行的，并且优先地覆盖一个地理位置或与另一个相比的时间。第二种修改使用前进轨道并允许轨道的远地点相对于太阳偏移恒定的量，从而覆盖相对于其他天的不同时间。根据本发明的特别优选方式，远地点总是指向太阳。

摘要： A non-geostationary low earth orbit satellite constellation using elliptical orbits with apogees in the Northern Hemisphere to provide continuous coverage over the Continental United States of America (CONUS), and by extension to the other points in the Northern Hemisphere situated above 25.degree. north latitude. The constellation provides time-continuous visibility with at least one satellite to any point above 25.degree. North latitude. An extension of the constellation has a combination of the elliptical orbits and at least one equatorial orbit to provide virtual global coverage. The distribution of capacity is deployed in proportion to the distribution of populations in the land masses of the earth. Time continuous visibility with at least one satellite is maintained by any point on earth north of the 50.degree. South latitude, with a minimum number of satellites deployed. All satellites sharing the same orbit, or type of orbit, in the constellations above have the same orbital period, same apogee altitude and same perigee point. For all elliptical orbits in the constellation herein the argument of perigee can be adjusted to provide optimal service to specific regions (CONUS, Northern Europe, etc.)
摘要翻译：一个非对地静止的低地球轨道卫星星座使用北半球的远地点的椭圆轨道，为美国大陆（CONUS）提供连续的覆盖，并延伸到北纬25度以北的北半球。星座提供时间连续的可见性，至少有一颗卫星到达北纬25度以上的任意一点。星座的延伸具有椭圆轨道和至少一个赤道轨道的组合，以提供虚拟的全球覆盖。能力分配与地球上的人口分布相当。至少有一颗卫星的时间连续可见度由南纬50度以北的地球任意一点维持，部署卫星数量最少。在上述星座中共享相同轨道或轨道类型的所有卫星具有相同的轨道周期，相同的远地点高度和相同的近地点点。对于星座中的所有椭圆轨道，可以调整近地点参数，以便为特定地区（CONUS，北欧等）提供最佳服务。
