Abstract
The ability to communicate anytime and anywhere across the global or regional customer base is key to commercial success. During the first generation of GMSS satellites the geosynchronous (GSO) orbit was chosen as the optimum for many reasons. INMARSAT is the result of an excellent space systems architecture approach during the 1970’s, 80’s, and 90’s. However, global changes during the 90’s drove satellite communications architectures to alternative concepts and orbits. Diverse factors such as customer mobility, customer diversity, smaller subscriber units, increasingly powerful spaceborne processors, commercial launches, global telecommunications deregulation, and global wealth enabled visionaries to pick alternatives for telecommunications constellations for the mobile user.
