Global Positioning System Precision Encrypted (Y) Code Approach/Landing at Civil Airfields Navy SBIR FY2012.1 Sol No.: Navy SBIR FY2012.1 Topic No.: N121-030 Topic Title: Global Positioning System Precision Encrypted (Y) Code Approach/Landing at Civil Airfields Proposal No.: N121-030-1311 Firm: Solute, Inc. 4250 Pacific Highway Suite 211 San Diego, California 92110-3222 Contact: Mark Anderson Phone: (619) 758-9900 Web Site: http://www.solute.us Abstract: The US military has a need for a navigation system to support precision approaches using equipment installed and resident on tactical aircraft. Ideally, modifications to the installed equipment would be limited to software updates. Solute's approach focuses on modifying the integrity software included in military GPS receiver to provide the accuracy, availability, and integrity necessary to safely perform approaches in weather requiring precision minimums. Benefits: In addition to the F-18, other airborne platforms within the DoD that rely on GPS for navigation represent opportunities for technology transition. While the F/A-18 will be used as a grounding test bed for the initial proof of concept, the overall system architecture and methodology will remain sufficiently generalized to allow its application to other airborne platforms. The V22-Osprey (PMA-275), the AV-8B Harrier II (PMA-257), and the F-35 Lighting II platforms (The JSF program) all currently poses GPS navigation capabilities that could be substantially enhanced by the approach developed through this SBIR research. These platforms represent airframes that have advanced GPS receivers, fly combat missions, and have very limited opportunities to add extra hardware. The ability to perform precision approaches using hardware currently installed will be a useful capability that will improve safety and enhance flexibility during deployments. Return
