AI Contract Overview
The Boosting Innovative GEOINT-Science and Technology (BIG-ST) Broad Agency Announcement, identified as HM047623BAA0001 Revision 3, is an ongoing federal solicitation by the National Geospatial-Intelligence Agency to advance innovation in geospatial intelligence through research in three core technical domains: Foundational GEOINT, Advanced Phenomenologies, and Analytic Technologies. Proposals are not accepted under the general solicitation but must be submitted in direct response to specific Topic Calls issued periodically through official channels including Sam.gov, Grants.gov, and the Classified IC-Acquisition Research Center. Topic Calls are the only mechanism for submission, with deadlines and requirements detailed individually for each, and only those submitted in response to an open Topic Call will be considered for review. The general solicitation remains active until December 14, 2026, but individual topics have targeted open and closed windows. Several topics have been closed or canceled, including Geospatial-Intelligence Foundational Model, Magnifying University Science Expertise, VLBI+G Signal Chain Development, and Production of Radio Frequency Surveys from Commercial On-orbit Passive RF. Currently, only Topic 6 – Magnifying University Science Expertise 2 (MUSE 2) is open, exclusively for grant applicants, with all documentation and revisions hosted on Grants.gov. Updates to Topic 6 included multiple revisions to the solicitation document and appendices, with the abstract submission window closing on March 31, 2026. Interested parties must monitor official websites for new Topic Calls and maintain access to the Classified IC-ARC if dealing with classified materials, using the provided support contacts for account assistance. The primary point of contact for grant-related inquiries is Patricia Mercer-Bey, the Grant Specialist at the NGA.
