Abstract
A method of increasing satellite communication quality by using a MEO satellite constellation ( ) and a LEO satellite constellation ( ) in combination with a decision algorithm which selects the appropriate constellation to route a communication signal through. The decision algorithm can be embodied in three ways: gateway based ( ), individual subscriber unit based ( ) and satellite based ( ). The MEO constellation ( ) and LEO ( ) constellation may be cross-linked, allowing for switching of service between satellites, as needed, during a communication session.
