Slingshot Aerospace, Inc., the leader in AI-powered solutions for satellite tracking, space traffic coordination, and space modeling and simulation, announced it has worked with the Defense Advanced Research Projects Agency (DARPA) to successfully create a new artificial intelligence (AI) system, called Agatha, that identifies anomalous spacecraft within large satellite constellations.
Several large satellite constellations of over 10,000 spacecraft are slated for deployment by international government and commercial space operators in the coming years, which will dramatically increase the number of satellites in low Earth orbit (LEO). With so many satellites, it becomes increasingly important to be able to verify that satellites are operating within the constellations’ stated purposes.
“Agatha represents a breakthrough in how AI can deliver unparalleled space domain awareness, as its ability to find these needles in the haystack is something no human, or team of humans, could possibly execute,” said Dr. Dylan Kesler, Director of Data Science and AI, Slingshot Aerospace. “Identifying malfunctioning or potentially nefarious objects and their objectives within large satellite constellations is a complex challenge that required us to reach beyond traditional approaches and develop a novel and scalable AI algorithm. Our Agatha model has also proven its ability to deliver high-quality insights that provide ‘explainability’ or context for why specific objects were flagged.”

Slingshot’s Agatha was trained on over 60 years of simulated constellation data that Slingshot created. Slingshot then closed the so-called “sim-to-real transfer” gap and proved-out the system by finding non-nefarious outliers in operational, real-world commercial constellations. After identifying a number of outlier satellites within those constellations, Slingshot successfully confirmed with the respective satellite operators that the identified satellites did differ from the others in hardware, mission, and/or operational parameters.
Agatha AI incorporates cutting-edge approaches to AI data analysis, including inverse reinforcement learning (IRL) – a technique that uses AI to evaluate behaviors and identify the policies and intentions of the objects it tracks. IRL reaches beyond identifying individual outlier maneuvers (see Slingshot’s reporting on the Russian satellite Luch (Olymp) 2) and focuses on answering the strategic questions of why satellites are exhibiting specific behaviors and what their intentions are. Further, Agatha doesn’t require cues on where to look for outliers – the data-agnostic model ingests massive amounts of space information and identifies anomalies as it finds them.
“As space activity shifts from satellites owned by a small number of operators to massive constellations operated by an array of owners, the need for transparency increases,” said Kesler. “The ability to quickly identify anomalies – whether a malfunctioning spacecraft or an intentionally nefarious ‘wolf in sheep’s clothing’ – is an increasingly important aspect of maintaining safety and security in space and on Earth.”
“Having worked previously in the BioTech world and with gene editing technologies like CRISPR, I know that tools like Agatha and approaches like inverse reinforcement learning almost certainly would have helped us find anomalies in the oceans of genomic data we analyzed,” continued Kesler. “Inverse reinforcement learning is an AI technique on the bleeding edge of development and we expect its use to grow exponentially in the years to come to solve a variety of problems, not just in space.”
