Chinese researchers simulate targeting Starlink satellites with AI
Chinese researchers have demonstrated a computer simulation showing that 99 Chinese satellites equipped with lasers and other devices could approach and potentially target nearly 1,400 Starlink satellites within 12 hours using an AI algorithm inspired by whale hunting techniques. The research, led by Wu Yunhua at Nanjing University of Aeronautics and Astronautics, reportedly aims to counter perceived military threats from Starlink's use in potential Taiwan conflicts.
What happened
Wu Yunhua, director of the aerospace control department at Nanjing University of Aeronautics and Astronautics, led a team that demonstrated in a computer simulation that nearly 1,400 Starlink satellites could be approached within 12 hours using just 99 Chinese satellites equipped with lasers, microwaves, and other devices for reconnaissance, tracking, or other operations.
The simulation used a binary artificial intelligence algorithm inspired by the hunting techniques of whales. According to the team, their technology can generate a reliable action plan within two minutes. The research was published on January 3 and was reported by South China Morning Post.
Reported impact
Chinese researchers stated that the militarisation of space has intensified and poses a significant threat to China's space security, citing the potential military application value of the Starlink mega constellation highlighted in the Russia-Ukraine conflict.
Starlink, operated by SpaceX, has already launched over 6,700 satellites with plans to expand this number significantly. The research aims to track and monitor Starlink's operational status.
Index analysis
The algorithm helps Chinese satellites work in tandem to identify and approach Starlink satellites effectively. The hunting behavior of whales, which channel small fish into their mouths while conserving energy, provided the foundation for this method. Precise orbital calculations are required to maneuver satellites close enough to detect Starlink satellites, and energy-intensive equipment like lasers requires adequate sunlight for recharging.
Governance controls
Wu's team has received more than 16 million yuan (approximately $2.2 million) in funding from the Chinese government and military. The Harbin Institute of Technology also collaborated on the research.
