Assured position, navigation and time (PNT) require constant vigilance against intentional and unintentional sources of coherent and non-coherent interference. The Global Positioning System (GPS) is especially vulnerable to attacks and must be defended through electronic protection (EP) measures such as anti-jam (AJ) and anti-spoof (AS). The proposed effort will design and demonstrate GPS-based attitude (GPS/A) determination algorithms in conjunction with algorithms for direction-finding (DF), anti-jam, spoof detection and mitigation, and demonstrate those algorithms with real-time embedded hardware. At the conclusion of the Phase I effort Toyon will demonstrate the DF/AJ/AS and GPS/A performance of a brassboard system under the presence of both coherent and non-coherent sources of interference with minimal phase distortions to the received GPS signal. The demonstration results will be used to design a prototype system that will be developed, fabricated, and demonstrated under operational conditions during the Phase II effort.
