Sentient is a classified artificial intelligence (AI)–powered satellite-based intelligence analysis system developed and operated by the National Reconnaissance Office (NRO) of the United States. Described as an artificial brain, Sentient autonomously processes orbital and terrestrial sensor data to detect, track, and forecast activity on and above Earth. The system integrates machine learning with real-time tip-and-cue functionality, enabling coordinated retasking of reconnaissance satellites without human input.
