The Defense Threat Reduction Agency (DTRA) is seeking innovative solutions through the Small Business Innovation Research (SBIR) program to develop cognitive mapping algorithms aimed at enhancing counter-weapons of mass destruction (WMD) operations. The objective is to create 2D or 3D maps of building interiors by integrating architectural knowledge into traditional Simultaneous Localization and Mapping (SLAM) techniques, thereby improving situational awareness in GPS-denied environments. This initiative is critical for enabling DTRA and its partners to execute missions effectively, particularly in complex structures where conventional mapping methods may fall short. Interested parties should note that the solicitation is set to open on June 25, 2025, with applications due by July 23, 2025, and further details can be found at the DOD SBIR website.
