IARPA LocUS — Location Using Sound

IARPA LocUS, short for Location Using Sound, is an IARPA program under the Emerging Technology Accelerator that aims to geolocate video content from audio and visual signals when metadata is missing. It serves intelligence analysts who need to place open-source footage in context by combining acoustic cues with image analysis. The program uses prototype other transaction agreements, and the available notices describe a rolling white paper process rather than a fixed annual deadline. The first wave was due on 30 June 2026, and the program page does not publish a dollar cap. Eligibility is centered on U.S.-based primes, with small businesses, non-traditional contractors, and nonprofits welcome; foreign organizations can join as subcontractors, while government agencies, FFRDCs, and UARCs are excluded. LocUS fits teams that can turn multimodal signal processing into a practical geolocation workflow for unclassified video. A strong submission will show how audio events, visual landmarks, and probabilistic reasoning are tied together in a way that can survive real analyst use. Because the process begins with a white paper and can move to a full proposal only after screening, applicants need a clear technical path rather than a broad concept.
