Abstract:	Satellite-borne GPS receivers are used for navigation and control surveillance as well as remote sensing of the Earth’s Ionosphere and Troposphere. The modernization of GPS and the availability of new signals (such as those provided by the L5, Galileo, several LAAS and WAAS systems, and several radio beacons) will make increased demands on the satellite-borne receiver technologies. However, these requirements call for some relatively small but significant alterations in the receiver architectures. Because of the limited use of such receivers, the conventional hardware architecture is not cost-effective. A software-based architecture for real-time satellite-borne receivers have been developed and tested in the laboratory. The architecture utilizes orbital aiding (similar to Ultra Tightly Coupled Integration of GPS/INS) in order to provide superior acquisition and tracking sensitivity under high Doppler conditions. The architecture has been optimized for space-worthy operations in terms of size, weight, power consumptions and space environment. Such receivers will provide the flexibility and vertical growth necessary for future space missions.
