Abstract :
Use of satellite systems in non-geostationary orbits for mobile communications is of wide interest. The paper presents a satellite system to meet the mobile voice and data (up to 4.8 kbps) communications requirements for users equipped with hand-held terminals in rural and unshadowed areas of the limited region of the globe bounded by 40°N and 40°S latitudes. After analysing the effect of parameters which have dominant effect on the definition of the space segment the paper establishes that by restricting the coverage requirements to this limited region the overall system would be much simpler to implement and manage. Finally the paper brings out how in comparison to other systems this scheme meets the system objectives most optimally with regard to both cost and complexity
