The Department of Defense, specifically the Navy, is seeking innovative solutions through the Small Business Innovation Research (SBIR) program to develop a passive system for validating Automatic Dependent Surveillance-Broadcast (ADS-B) tracks, which is crucial for collision avoidance during missions that require emissions control. The objective is to create technology that allows unmanned aircraft systems (UAS) to independently validate ADS-B data without relying on active sensors, particularly in scenarios where radio frequency emissions must be minimized or eliminated. This initiative is vital for ensuring the safety of military operations in international airspace while maintaining compliance with aviation regulations. The solicitation is currently in the pre-release phase, with an open date set for January 8, 2025, and a close date for applications on February 5, 2025. Interested parties can find more information and submit proposals through the official SBIR website at https://www.dodsbirsttr.mil/topics-app/.
