CONTINUOUS COVERAGE OF THE NORTH POLAR REGION WITH ONLY TWO COMMUNICATIONS SATELLITES

The problem of providing continuous coverage of the north polar region with a small number of communications satellites is considered. The system described requires only two satellites to provide both this coverage and coverage of a considerable fraction of the northern hemisphere. Two orbit planes...
