A key national security issue is maximizing the military benefits of GPS while minimizing the risks. The denial of GPS to enemies during conflicts without denying GPS to friendly forces is required to assure dominance. The most effective method of protecting GPS from jamming is through providing a high power GPS signal; e.g. from a geostationary augmentation. Similarly, the most effective of denying GPS C/A code is through jamming the GPS signal with a high poer broadband noise or CW source at Ll (1575.42 MHz). However, the power required to continuously transmit a jamming signal over an interdicted area limits the application of long duration high altitude UAVs or space-based resources as jammer platforms.In this proposal, a low power method of selective denial is proposed that is suitable for use by space systems or high altitude UAV platforms. Under this effort, NAVSYS proposes to develop a preliminary space system architecture and design for a GPS augmentation system to provide both protection and selective denial from space.
