High Integrity SWAP-C Optimized GPS/Anti-Jam/IMU Navigation System (HI-GAINS) for Unmanned Aircraft

The objective of this NAVAIR SBIR program is to develop an integrated global navigation system capable of providing secure SAASM GPS based navigation in the presence of jamming, spoofing or electromagnetic interference (EMI) while meeting the stringent size, weight and power (SWaP) constraints imposed by Group 2 Unmanned Aircraft Systems. In the Phase I of this SBIR program, Mayflower developed an innovative system architecture termed HI-GAINS, and evaluated its feasibility in meeting the Navys requirements for STUAS navigation performance within the SWaP-C constraints. Mayflower proposes to develop and implement the HI-GAINS design on a prototype platform based on Mayflower NavGuard Anti-Jam SAASM GPS receiver, an IMU and other COTS components and software algorithms for spoofing mitigation in the Phase II of this SBIR program and demonstrate its performance in the laboratory and at Facilities for Antenna and RCS Measurements (FARM) at NAVAIR, Patuxent River, MD. In a follow-on Phase II.5/III program Mayflower anticipates to mature HI-GAINS Phase II prototype and develop a form fit production ready prototype suitable for use on the Navy STUAS platform.
