China Simulates Jamming Starlink Over Taiwan

A study estimates 935 to 2,000 airborne jamming devices are needed to disrupt Starlink over Taiwan, highlighting the complexity of electronic warfare against a resilient satellite network.

  • On Nov. 5, Chinese researchers from Zhejiang University and the Beijing Institute of Technology published a peer‑reviewed paper concluding disrupting Starlink over Taiwan requires a massive electronic‑warfare force.
  • After Starlink aided Ukraine, Chinese military planners began assessing how to disrupt the system in a Taiwan conflict and focused on realistic interference methods, researchers said.
  • Using cheaper 23 dBW power sources would push the requirement to around 2,000 airborne units, with researchers estimating 1,000 to 2,000 airborne devices are needed to jam Starlink over roughly 13,900 square miles.
  • Defense planners may need to prepare for massive electronic‑warfare deployments, as Taiwanese expert Cathy Fang warns against relying solely on foreign satellites after lessons from Ukraine.
  • Because its orbital geometry constantly shifts, Starlink's thousands of low Earth orbit satellites rapidly switch links, making traditional ground-based jamming insufficient while classified Starlink anti-jamming details create uncertainty, researchers said.
