Research Institution
The objective of this proposal is to develop Selective Availability Anti-Spoofing Module (SAASM) compliant GPS receiver for Geosynchronous Earth Orbit (GEO) applications. In this proposal, we explore an approach to design the GEO GPS SAASM receiver based on improved techniques for signal acquisition (or detection) and then signal tracking (and demodulation) of weak GPS signals. GPS signals available at high GEO are 10-100 times weaker than signals received on Earth or at Low Earth Orbits (LEO). Thus, our key objectives are to design and develop acquisition and tracking modules capable of detecting and demodulating the weak satellite signals, of the order of -180 dBW. We envision the final outcome of this project to be a space-borne, space-qualified GPS receiver targeted for high altitude applications that can operate effectively in the full range from LEO to GEO and beyond.
