The Department of Defense, specifically the Naval Surface Warfare Center Carderock, is seeking innovative technologies for Assured Positioning, Navigation, and Timing (A-PNT) to be integrated with Combatant Craft and Unmanned Surface Vessels (USVs). The objective is to identify solutions that can maintain reliable navigation capabilities in environments where GPS signals are unreliable or compromised, particularly for maritime operations. This initiative is crucial for enhancing the operational effectiveness of USVs under contested conditions, with a focus on technologies such as advanced GPS/GNSS receivers, anti-jamming antennas, and inertial navigation systems. Interested parties must submit their applications by January 10, 2025, and can direct inquiries to Mike Rossik at michael.e.rossik.civ@us.navy.mil or Dennis Danko at dennis.p.danko.civ@us.navy.mil.
