Satellite / PCN Compatibility for Worldwide Mobility based on Resonant Sun - Synchronous Orbits

This paper reviews some basic equations of motion and coverage of satellites in earth orbit as well as examining satellite constellation design techniques. Specific orbit properties are highlighted and their applicability to constellation design and earth coverage are then investigated. A PCN oriented satellite constellation is then proposed with some unique properties. The proposed constellation scheme allows for a reduction in overall system cost in two ways. Firstly, simplification in satellite design result in satellite development costs being reduced and secondly, because each satellite will be designed for a particular orbit, constellation lifetime can be significantly extended.
