Iranian authorities have escalated their digital suppression tactics by deploying sophisticated jamming technologies against SpaceX’s Starlink satellite internet service, which had become a vital communication tool for citizens amid widespread protests. The campaign represents a significant evolution in Tehran’s censorship capabilities, targeting both GPS signals and satellite transmissions simultaneously.
The crackdown intensified on January 8, 2026, when Iranian regulators implemented massive internet and telephone network blackouts. While partial service was later restored, severe restrictions remain in effect. The regime’s latest offensive focuses on disrupting Starlink’s satellite connectivity through multiple interference methods.
According to data from gpsjam.org, significant GPS interference was detected in Tehran and surrounding areas on January 8, coinciding with the internet shutdown. Professor Kave Salamatian of Savoie University explains that GPS jamming represents a classical method for disrupting Starlink services, as terminals rely on GPS signals to orient their antennas toward satellites.
However, the interference extends beyond GPS disruption. Victoria Samson of the Secure World Foundation reports data loss rates between 30-80%, indicating active signal jamming where transmission channels are saturated with noise or false signals. This sophisticated approach suggests Iranian authorities may be employing advanced electronic warfare systems, potentially including Russian-made Murmansk-BN jammers or domestic equivalents like the Cobra-V8 system developed at specialized institutions such as Imam Hossein University and Sharif University.
SpaceX has responded with technical countermeasures. A recent software update enables Starlink terminals to bypass GPS jamming through satellite-based triangulation and automatically reroute signals to unaffected satellites when interference is detected. While this has significantly reduced data loss, the update compromises terminal mobility as devices struggle to maintain connections while in motion.
According to Nasnet, Iran’s largest Starlink community, service remains functional despite concentrated interference around Tehran characterized by temporary, non-persistent disruptions. The cat-and-mouse game continues with approximately 50,000 Starlink terminals serving a small fraction of Iran’s 90 million population, highlighting both the technological arms race and the limitations of satellite internet as a comprehensive solution against state-level censorship.
