AARO’s GREMLIN (Ground-based, Remote, Electro-Magnetic, Layered, Integrated Network) is the first dedicated purpose-built UAP detection system ever deployed by the US government. Developed by the Georgia Tech Research Institute. Architecture: a network of 2D radar (range and azimuth), 3D radar (range, azimuth, and elevation), and long-range electro-optical and infrared telescopes. Tested successfully in March 2024. Deployed to a classified national security site for a 90-day pattern-of-life collection campaign starting late 2024. CRITICAL INTELLIGENCE DETAIL: AARO director Kosloski’s verbatim explanation for site selection (DefenseScoop transcript): “We chose that specific location because of the environment. We expect there to be a lot of variety in the types of things that we’re going to see. And there had been UAP reports in that general area. And we’re trying to build a baseline.” Translation: AARO knows which national security sites have recurring UAP activity and chose a pre-known UAP hotspot to baseline their sensor against. The specific site is classified but Kosloski confirmed it’s already in AARO’s geographic bias of reports near national security facilities. The sensor is designed specifically to counter the problems that plague legacy UAP footage: sensor calibration errors, parallax distortion, forced perspective artifacts, and lack of multi-sensor corroboration. AARO has also published technical reports on how sensor artifacts create false UAP characteristics — acknowledging the data quality problem explicitly. GREMLIN represents the first attempt to get calibrated, multi-domain, simultaneous sensor coverage of a UAP-active site.
