The Department of Defense, specifically the Army, is seeking proposals for the development of a Single Aperture Night plus Polarization Compass (SANPC) through the Small Business Innovation Research (SBIR) program. The objective is to create a celestial compass that integrates night and polarization channels into a single aperture, enhancing operational effectiveness for soldiers by providing accurate azimuth solutions even under challenging twilight conditions. This innovative system aims to reduce weight, complexity, and cost while ensuring high accuracy in both night and polarization modes. Interested parties can submit Direct to Phase II proposals with a funding amount of up to $2,000,000 for a 24-month performance period, with the application due by June 25, 2025.
