Chinese researchers studying how to disrupt Starlink satellite Internet in Taiwan during a potential cross-strait conflict found that it would take an extensive 1,000 to 2,000 airborne devices to effectively jam the system.
The study was published on Nov. 5 in the peer-reviewed journal Systems Engineering and Electronics and reported on by the South China Morning Post yesterday.
When Russia invaded Ukraine in February 2022, Kyiv quickly requested satellite Internet from founder Elon Musk, and thousands of Starlink terminals arrived within days, restoring command across the battlefield, despite Russia’s attempts to block communications, the paper reported.

Updates to SpaceX satellite configurations and software thwarted repeated jamming attempts by Russia, and the battlefield advantage shifted to Ukraine, the report said.
The success of Starlink in Ukraine prompted China to assess how to conduct electronic warfare should a conflict break out in the Taiwan Strait and Taiwan acquire Starlink’s assistance, it said.
In their peer-reviewed study, the team from Zhejiang University and the Beijing Institute of Technology found that disrupting Starlink across an area comparable to Taiwan is achievable only with a massive electronic warfare force.
As Starlink uses thousands of low-orbit satellites, which can shift connections in seconds if one satellite is jammed, traditional ground-based jamming methods would not be sufficient to suppress the system, the study said.
The team found that China would need to deploy at least 935 small, synchronized airborne jammers carried by drones, balloons or aircraft that could form a wide electromagnetic barrier over the combat zone.
This would be able to suppress Starlink over an area of about 36,000km², about the size of Taiwan, the research said.
If lower-powered airborne jammers were used instead, it would require about 2,000 devices, it said.
These figures do not consider backups for failures, terrain interference or future Starlink upgrades, so the actual number of jammers required may be even greater, it added.
The team also said that the results remain preliminary, as many of Starlink’s core technologies remain classified.
The disruption of 941 flights in and out of Taiwan due to China’s large-scale military exercises was no accident, but rather the result of a “quasi-blockade” used to simulate creating the air and sea routes needed for an amphibious landing, a military expert said. The disruptions occurred on Tuesday and lasted about 10 hours as China conducted live-fire drills in the Taiwan Strait. The Civil Aviation Administration (CAA) said the exercises affected 857 international flights and 84 domestic flights, affecting more than 100,000 travelers. Su Tzu-yun (蘇紫雲), a research fellow at the government-sponsored Institute for National Defense and Security Research, said the air
Trips for more than 100,000 international and domestic air travelers could be disrupted as China launches a military exercise around Taiwan today, Taiwan’s Civil Aviation Administration (CAA) said yesterday. The exercise could affect nearly 900 flights scheduled to enter the Taipei Flight Information Region (FIR) during the exercise window, it added. A notice issued by the Chinese Civil Aviation Administration showed there would be seven temporary zones around the Taiwan Strait which would be used for live-fire exercises, lasting from 8am to 6pm today. All aircraft are prohibited from entering during exercise, it says. Taipei FIR has 14 international air routes and
Taiwan lacks effective and cost-efficient armaments to intercept rockets, making the planned “T-Dome” interception system necessary, two experts said on Tuesday. The concerns were raised after China’s military fired two waves of rockets during live-fire drills around Taiwan on Tuesday, part of two-day exercises code-named “Justice Mission 2025.” The first wave involved 17 rockets launched at 9am from Pingtan in China’s Fujian Province, according to Lieutenant General Hsieh Jih-sheng (謝日升) of the Office of the Deputy Chief of the General Staff for Intelligence at the Ministry of National Defense. Those rockets landed 70 nautical miles (129.6km) northeast of Keelung without flying over Taiwan,
City buses in Taipei and New Taipei City, as well as the Taipei MRT, would on Saturday begin accepting QR code payments from five electronic payment providers, the Taipei Department of Transportation said yesterday. The new option would allow passengers to use the “transportation QR code” feature from EasyWallet, iPass Money, iCash Pay, Jkopay or PXPay Plus. Passengers should open their preferred electronic payment app, select the “transportation code” — not the regular payment code — unlock it, and scan the code at ticket readers or gates, General Planning Division Director-General Liu Kuo-chu (劉國著) said. People should move through the
