Chinese researchers from Zhejiang University and the Beijing Institute of Technology published a peer-reviewed study on November 5, 2025, in the journal Systems Engineering and Electronics, simulating large-scale electronic warfare to disrupt Starlink’s downlink signals over an area the size of Taiwan. The analysis demonstrates that jamming mega-constellations like Starlink is feasible using 935 to 2,000 electronic warfare drones spaced several kilometers apart at around 20 km altitude, creating an airborne electromagnetic barrier with narrowband and broadband jammers to overcome the network’s dynamic satellite handoffs and low-Earth orbit mobility. While highlighting China’s advancing capabilities in countering foreign satellite dependencies critical to regional security, the study notes significant challenges, including synchronization needs, terrain variations, and exclusions of enemy air defenses or Starlink upgrades, underscoring the resource-intensive nature of such operations amid Indo-Pacific tensions.​
