摘要:
The present invention relates to satellite systems and more particularly, to the provision of a novel, non-geostationary satellite system and method for weather and climate monitoring, communications applications, scientific research and similar tasks, with global coverage. Contrary to the teachings in the art it has been discovered that global coverage may be obtained using a constellation of six satellites in two orthogonal, 24 sidereal hour orbits (geosynchronous) with inclinations of 70° to 90°, and eccentricities of 0.275 - 0.45. By placing three of the satellites in a first orbit with an apogee over the north pole, and three of the satellites in a second, orthogonal orbit with an apogee over the south pole, global coverage may be obtained. As well, the satellites in these orbits avoid most of the Van Allen Belts.

本发明涉及卫星系统,更具体地说,涉及提供用于天气和气候监测,通信应用,科学研究和类似任务的新颖的非对地静止卫星系统和方法,其中全球 覆盖。 与本领域的教导相反,已经发现可以使用在两个正交24个恒星时间轨道(地球同步)中具有70°倾角的六颗卫星的星座来获得全球覆盖。 到90°,以及0.275-0.45的偏心率。 通过将三颗卫星放置在北极的远地点的第一轨道上,并将三颗卫星置于与南极的远地点正交的第二轨道上,可以获得全球覆盖。 同样,这些轨道上的卫星避开了大部分范艾伦带。 p>
