A new simulation by Chinese defense researchers suggests that jamming Starlink coverage over an area the size of Taiwan is technically possible.
Instead of focusing on whether Starlink can be jammed in theory, Chinese military planners are increasingly concerned with how such a feat could be attempted in a real conflict over Taiwan. The challenge is staggering: Taiwan and its allies could rely on a constellation of more than 10,000 satellites that hop frequencies, reroute traffic and resist interference in real time.
However, a recent simulation study by Chinese researchers delivers the most detailed public attempt yet to model a potential countermeasure.
Published on November 5 in the peer-reviewed journal Systems Engineering and Electronics, the paper concludes that disrupting Starlink across an area comparable to Taiwan is technically achievable – but only with a massive electronic warfare (EW) force.
Dynamic Starlink network poses major hurdle for EW
Rather than treating Starlink as a static system, Chinese researchers emphasize that its constantly shifting geometry is the real obstacle. In their peer-reviewed study, the team from Zhejiang University and the Beijing Institute of Technology notes that the constellation’s orbital planes are continuously changing, with satellites moving in and out of view at all times.
This dynamic behavior creates extreme uncertainty for any military attempting to monitor, track or interfere with Starlink’s downlink signals, the South China Morning Post reports. Unlike older satellite networks that depend on a few big geostationary satellites parked over the equator, Starlink behaves nothing like a fixed target.
Traditional systems can be jammed by simply overpowering the signal from the ground, but Starlink changes the equation. Its satellites are low-orbit, fast-moving and deployed by the thousands. A single user terminal never stays linked to just one satellite – it rapidly switches between several, forming a constantly shifting mesh in the sky. As the researchers explain, even if one link is successfully jammed, the connection simply jumps to another within seconds, making interference far harder to sustain.
Distributed jamming swarms seen as the sole viable method
Yang’s research team explains that the only realistic countermeasure would be a fully distributed jamming strategy. Instead of using a few powerful ground stations, an attacker would need hundreds – or even thousands – of small, synchronized jammers deployed in the air on drones, balloons or aircraft. Together, these platforms would form a wide electromagnetic barrier over the combat zone.
The simulation tested realistic jamming by having each airborne jammer broadcast noise at different power levels. Researchers compared wide‑beam antennas that cover more area with less energy to narrow‑beam antennas that are stronger but require precise aiming. For every point on the ground, the model calculated whether a Starlink terminal could still maintain a usable signal.
The Chinese researchers calculated that fully suppressing Starlink over Taiwan, roughly 13,900 square miles, would require at least 935 synchronized jamming platforms, not including backups for failures, terrain interference, or future Starlink upgrades. Using cheaper 23 dBW power sources with spacing of about 3 miles would push the requirement to around 2,000 airborne units, though the team stressed the results remain preliminary since key Starlink anti‑jamming details are still confidential.

October 3, 2025 (Update)
On Thursday evening (October 2), several drones were sighted in the vicinity of and on the grounds of Munich Airport. The first reports were received at around 8:30 p.m. Initially, areas around the airport, including Freising and Erding, were affected.
The state police immediately launched extensive search operations with a large number of officers in the vicinity of the airport. At the same time, the federal police immediately carried out surveillance and search operations on the airport grounds. However, it has not yet been possible to identify the perpetrator.
At around 9:05 p.m., drones were reported near the airport fence. At around 10:10 p.m., the first sighting was made on the airport grounds. As a result, flight operations were gradually suspended at 10:18 p.m. for safety reasons. The preventive closure affected both runways from 10:35 p.m. onwards. The sightings ended around midnight. According to the airport operator, there were 17 flight cancellations and 15 diversions by that time. Helicopters from the federal police and the Bavarian state police were also deployed to monitor the airspace and conduct searches.
Munich Airport, in cooperation with the airlines, immediately took care of the passengers in the terminals. Camp beds were set up, and blankets, drinks, and snacks were provided. In addition, 15 arriving flights were diverted to Stuttgart, Nuremberg, Vienna, and Frankfurt. Flight operations resumed as normal today (Friday, October 3).
Responsibilities and cooperation
Within the scope of their respective tasks, the German Air Traffic Control (DFS), the state aviation security authorities, the state police forces, and the federal police are responsible for the detection and defense against drones at commercial airports.
The measures are carried out in close coordination between all parties involved and the airport operator on the basis of jointly developed emergency plans. The local state police force is responsible for preventive policing in the vicinity of the airport, while the federal police is responsible for policing on the airport grounds. Criminal prosecution is the responsibility of the state police.
Note: Please understand that for tactical reasons, the security authorities are unable to provide any further information on the systems and measures used. Further investigations will be conducted by the Bavarian police, as they have jurisdiction in this matter.

Danish police said on Tuesday that they did not know who was responsible for flying drones over Copenhagen airport the previous evening, but that they appeared to have been knowledgeable.
Overnight on Monday, the appearance of drones caused the main airports of both Denmark and Norway to close for several hours, causing flight diversions and other travel disruption. While flights are now resuming, heavy travel delays were expected to last throughout Tuesday.
“The number, size, flight patterns, time over the airport. All this together … indicates that it is a capable actor. Which capable actor, I do not know,” Danish police inspector Jens Jespersen told reporters at a press conference Tuesday morning.
The airport was closed for several hours before reopening early Tuesday, causing numerous delays and travel disruptions to 20,000 passengers, airport officials said.
Among those affected was European Commissioner Roxana Mînzatu, whose plane was diverted from Copenhagen to the Swedish town of Ängelholm.
Police said several large drones were seen over the Danish capital’s Kastrup airport on Monday. A heavy police presence was dispatched to investigate the drone activity, and the devices could be seen coming and going for several hours before flying away on their own.
“The drones have disappeared and the airport is open again,” Deputy Police Inspector Jakob Hansen told reporters. “We didn’t take the drones down,” he added.
Who dunnit?
Hansen said police were cooperating with the Danish military and intelligence service to find out where the drones had come from. He said police were also working with colleagues in Oslo after drone sightings in the Norwegian capital also caused the airport to close for several hours.
“We had two different drone sightings,” said Oslo airport spokeswoman Monica Fasting.
Though no culprit has been definitively identified, there is already speculation.
“Obvious to view the drones over Kastrup as a hybrid attack” was the title of a live blog post by Jakob Hvide Beim, defence editor at leading Danish newspaper Politiken. He went on to explain that the authorities have been warning about the risk of Russian hybrid attacks against Denmark “for some time now”.
Why Denmark specifically? Copenhagen’s track record of significant Ukraine support, Hvide Beim says, noting as example Denmark having “taken the lead by offering Ukrainian arms factories the opportunity to open production” in Denmark.
Ukrainian President Volodymyr Zelenskyy posted on X about a Russian incursion of Danish airspace on 22 September, albeit without providing proof or substantiating further.
Last night’s drone incursion over Denmark and Norway comes after a spate of Russian aerial incursions over NATO territory. Two weeks ago, Poland shot down several of the 20 Russian drones that entered its airspace which led Warsaw to activate NATO’s Article 4 – meaning it believes there is a credible threat to the country’s security.
Friday last week, Russian fighter jets entered Estonian airspace, lingering for 12 minutes and prompting Tallinn to likewise initiate conversations under the umbrella of Article 4, which will take place today.

A volunteer-run network of service centers halts custom firmware updates for DJI drones following a cyber attack.
Can a cyber operation have an impact on drone warfare? Recent developments in Russia offer an example of how this can happen in a not-so-obvious way.
On Friday, a volunteer group Russian Hackers for the Front (“Русские Хакеры – Фронту”, RH) known for building a customized firmware for DJI drones reported a cyber attack that affected its servers and end-point devices (terminals). While recovering from the attack, RH instructed hundreds of service centers to stop using its terminals until further notice, thus pausing a wide operation of weaponizing commercial drones.
Although details are scanty, this is a rare publicly reported cyber attack that affects drones warfare and might have militarily significant consequences.
In this post I will summarize what is known about the attack and provide additional information about the impact and who might be behind it.
