KAI Successfully Demonstrates AI-Based Autonomous Satellite Operation Technology in Space

Satellite independently analyzes fault causes and determines responses
Key technology verified to reduce reliance on ground stations
Full-scale demonstrations to begin in December... Plans to apply technology to next-generation satellites

Korea Aerospace Industries (KAI) has successfully demonstrated autonomous operation technology that uses artificial intelligence (AI) in orbit to diagnose satellite anomalies and determine responses.

KAI said on October 21 that it had successfully completed a pilot mission for AI-based autonomous satellite operation in orbit on October 20. The demonstration used a self-developed AI module aboard the BEE-1012 CubeSat, which entered space on October 7 in the fifth launch of the Nuri rocket.

The technology tested is "AI onboard processing," in which AI directly analyzes data collected by a satellite to identify the cause of an anomaly and determine a response.

In the demonstration, a ground station sent a simulated fault signal. The AI module aboard the satellite analyzed the cause and extent of the fault, generated a technical report outlining a response, and transmitted it to the ground station.

When an anomaly occurs, conventional satellites must transmit the relevant data to a ground station and wait for the analysis results. By contrast, AI-based autonomous operation technology enables a satellite to analyze anomalies on its own in orbit, reducing reliance on ground stations and the communications burden.

KAI adapted to the satellite sector its fault and service-life prediction and predictive maintenance technologies developed through aircraft development. It developed an AI module in-house trained on tens of thousands of failure scenarios, collaborated with defense AI company PunJin, and incorporated a neural processing unit (NPU) from domestic startup Mobilint.

Building on this pilot mission, KAI plans to begin full-scale demonstrations of the autonomous operation technology in December. The company aims to improve the technology's reliability and apply it as a core technology to various satellites it builds in the future.

"This demonstration verified that AI-based autonomous satellite operation technology works in space," said Seo Hyunseok, head of KAI's Space Business Division. "We will continue to advance space AI technology, apply it to next-generation satellite systems, and lead the global NewSpace market."
