Claim:
1. A method for operating one or more satellites in a non-geosynchronous orbit (NGSO) satellite constellation, the method comprising: determining a coverage area on Earth for a first beam transmitted from a first satellite in the NGSO satellite constellation; projecting a cone onto a first region of the beam coverage area, the first region of the beam coverage area corresponding to an area on the Earth's surface for which a power flux density (PFD) is greater than a threshold PFD level; defining a second region of the beam coverage area as including portions of the beam coverage area lying outside the first region, the second region of the beam coverage area not interfering with geosynchronous orbit (GSO) satellite communications; and determining a minimum arc angle for each of a plurality of points within the first region but not the second region of the beam coverage area.
