AbstractThe objective of this Navy SBIR program is to develop and incorporate the capability onboard military aircraft to conduct an approach to near-Category I precision utilizing Precision Encrypted Y Code available on both L1 and L2 signals from the Global Positioning System (GPS) satellites. Mayflower"s approach to meet the Navy objective in this SBIR program is to develop an innovative suite of algorithms and signal processing software enhancements for use on a dual-frequency SAASM GPS receiver (the enhanced receiver is referred to as HIPR) to meet the near-Category I approach and landing requirements of accuracy, integrity, continuity, and availability (high assurance). The proposed solution will not depend upon any signals from ground-based or space-based augmentation system (GBAS/SBAS). During the Phase I SBIR Program, Mayflower developed advanced integrity monitoring algorithms and analyzed the feasibility of meeting the requirements of near Category I approaches with a dual frequency SAASM GPS receiver enhanced with these algorithms. The results of the feasibility study have demonstrated that the Navy"s availability requirement for LPV-250 can be met with the current GPS constellation with the proposed HIPR solution. Mayflower NavAssure Dual Frequency SAASM P(Y) code GPS receiver will be used as the baseline for implementation and demonstration of the above software enhancements for the Phase II technology demonstration. The goal of the technology development in this SBIR program is to accomplish the program objectives via software-only upgrade to the SAASM GPS receiver in the existing aircraft navigation systems and also develop a 24 channel SAASM GPS receiver for use in newer Navy aircraft.
