How Iran and China Silenced 10,000 Starlink Terminals — Why Russia Launched Zorky (youtube.com)
RF and Microwave Jamming: Iranian security forces utilized high-powered Radio Frequency (RF) and microwave jammers to target the specific frequencies Starlink uses for communication. Packet Loss and Blackouts: These jamming efforts resulted in total packet loss and a complete communication blackout across the network. GPS Desynchronization: The attack also caused GPS desynchronization, which is critical for satellite terminals to maintain a lock on moving low-earth orbit (LEO) satellites. The blackout cost the Iranian government approximately $1.56 million USD per hour to maintain.
Russia is building Rasvet and China is building Guowang, targetting disruption of non national internet signals.
