Abstract

A telecommunications system is disclosed which includes a constellation (10) of satellites (12) equally deployed in four pairs (22) of circular, low Earth orbits (14, 15) inclined at fifty degrees with an interplane phase angle of zero degrees. The system enables two terminals (20) on the ground to communicate through a store-and-forward network.
