<p>The present invention relates to satellite systems and more particularly, to the provision of a satellite system for weather and climate monitoring, communications applications, and scientific research at higher latitudes, referred to as the polar cap and defined here as latitudes above 60°, in either the northern hemisphere or the southern hemisphere. Contrary to the teachings in the art it has been determined that a satellite system and method may be provided using satellites in 24 sidereal hour orbits (geosynchronous) with inclinations, orbital planes, right ascensions and eccentricities chosen to optimize coverage of a particular service area located at high latitudes. A constellation of two satellites can provide continuous coverage of the polar cap. The satellites in this orbits avoid most of the Van Allen Belts.</p> |
