Gravity-enhanced Covert Submarine Navigation Navy SBIR FY2014.1 Sol No.: Navy SBIR FY2014.1 Topic No.: N141-081 Topic Title: Gravity-enhanced Covert Submarine Navigation Proposal No.: N141-081-0872 Firm: AOSense, Inc. 767 N Mary Ave Sunnyvale, California 94085-2909 Contact: Miroslav Shverdin Phone: (408) 735-9500 Web Site: www.aosense.com Abstract: We propose a novel navigation paradigm that utilizes an arrangement of multiple gradiometers for covert submarine navigation. Our proposed Phase I research will analyze the feasibility and benefits of the proposed navigation technique and develop quantitative models to simulate submarine navigation under various representative CONOPs. In addition, we will develop a detailed design for a compact, highly accurate, cold-atom gravity gradiometer. We will configure a gravity gradiometers based on cold-atom interferometry in a highly robust, simple-to-operate, fieldable, and comparatively low-cost package. If successful, we plan to build and test the designed gravity gradiometer in Phase II of this SBIR. Benefits: Compact, high accuracy cold-atom gradiometers will substantially enhance covert submarine navigation by providing velocity bounding and positional fixes. In addition, the proposed sensor will enable highly accurate airborne gravity surveys. Airborne gravity surveys are extensively used by oil, gas, and mineral extraction companies for resource discovery and management. Return
