The Pentagon provided new details today about how its deployable, readily reconfigurable suite of sensors called GREMLIN works to help set the stage for figuring out what unidentified objects in our skies are and are not, if they appear at all.
In its annual report released on Thursday, the All-domain Anomaly Resolution Office (AARO) shared a graphic that gives us our best look yet at what its GREMLIN system is. It was developed by Georgia Tech Research Institute specifically to help gather data about so-called unidentified anomalous phenomena, or UAPs. That’s the DoD’s new parlance for what used to be called UFOs.
When AARO last discussed GREMLIN back in March, the office said the system was designed to provide “hyperspectral surveillance to try to capture these incidents.” However, no details were given about what kind of sensors were being used to capture data across different areas of the electromagnetic spectrum simultaneously.
Now deployed, GREMLIN includes 2D and 3D radars, long-range electro-optical/infrared sensors, GPS, satellite communications, aircraft tracking systems and radio frequency spectrum monitoring. It all feeds into a central node where the data can be fused to get a better sense of what’s out there. The system is something of an integrated air defense apparatus ‘in a box,’ allowing for multiple sensor types and open-source data to be captured on single targets within its view.
