Iran has taken unprecedented action by deploying military jammers to shut down Starlink satellite internet access across the country. This marks the first time a nation has systematically targeted Elon Musk’s satellite internet service, which has become a lifeline for protesters and anti-regime activists during government-imposed internet blackouts.
Iran Wire reports that despite tens of thousands of Starlink units operating inside Iran, the blackout has reached satellite connections. About 30 percent of Starlink’s uplink and downlink traffic was initially disrupted, quickly rising to more than 80 percent within hours.
Amir Rashidi from the Miaan Group told TechRadar, “I have been monitoring and researching access to the internet for the past 20 years, and I have never seen such a thing in my life.” Monitoring data shows a sudden drop in Starlink data packets, supporting reports from the ground that satellite connectivity has been heavily affected.
The Times of Israel reports that the deployment of Starlink receivers is now far greater in Iran than during previous blackouts. This comes despite the government never authorizing Starlink to function, making the service illegal to possess and use in the country.
The GPS jamming technique allows Iran to target specific regions rather than implementing nationwide disruption. This localized approach has created a patchwork of Starlink connectivity across different parts of the country, including near blackouts in some high-profile areas.
NetBlocks reported that Iran’s internet blackout passed the 60-hour mark with national connectivity levels continuing to flatline around 1 percent of ordinary levels.
How GPS Jamming Technology Blocks Satellites
Starlink receivers use GPS to locate and connect to satellites. Since Iran’s 12-day war with Israel last June, the country has been disrupting GPS signals. This disruption means shutdowns are localized, resulting in varying levels of connectivity across different regions.
The GPS jamming technique represents a new approach to internet censorship. Rather than simply blocking domestic internet providers, Iran is now actively jamming satellite signals that bypass traditional infrastructure.
Simon Migliano, who compiled a comprehensive report into recent internet shutdowns, explained that Iran’s current nationwide blackout is a blunt instrument intended to crush dissent. The kill switch approach comes at a staggering price, draining $1.56 million from Iran’s economy every single hour the internet is down.
Why Surveillance Concerns Raise Questions
Questions have emerged about whether Starlink’s satellite network is being used by the US government for surveillance purposes. The technology has dual-use capabilities that blur the line between civilian internet service and military intelligence gathering.
SpaceX has developed Starshield, a separate military-focused business unit adapted from Starlink. According to reports, Starshield satellites have imaging capabilities designed to provide the US government with continuous surveillance of nearly anywhere around the globe. The imaging capabilities are designed to have superior resolution over most existing US government spying systems.
Reuters revealed in 2024 that SpaceX has a $1.8 billion contract with the National Reconnaissance Office to build a spy satellite network consisting of hundreds of satellites. The satellites will enable continuous global surveillance capabilities for intelligence agencies.
Research from the Center for Strategic and International Studies indicates that Starlink utilizes cloud computing, big data, and artificial intelligence, giving it significant advantages in intelligence, reconnaissance, surveillance, and secure communication transmission. The system provides enhanced data transmission, reconnaissance, and strategic intelligence support capabilities for the US military.
The technology allows for all-weather situational awareness and continuous monitoring that single satellites cannot provide. Once completed, the 42,000-satellite network could cover areas where traditional land-based communication stations do not reach, including oceans and polar regions.
Security Risks and Government Access
Security concerns arose when Elon Musk’s team installed Starlink at the White House without informing communications experts. According to The Washington Post, the installation bypassed controls meant to stop leaks and hacking. The Starlink Guest WiFi network required only a password rather than username or two-factor authentication.
Democratic lawmakers raised concerns that the installation could undermine national security by exposing sensitive data to hackers or adversaries. Former NSA hacker Jake Williams told media outlets that the White House might be using Starlink to bypass existing security controls.
Multiple federal agencies have shown interest in Starlink services. Customs and Border Protection has explored using the technology for automated surveillance towers and communication-denied areas along the US border. The FBI and Drug Enforcement Administration have issued requests for information about deploying Starlink for field operations and tactical situations.
The close relationship between SpaceX and US government agencies has raised questions about potential conflicts of interest and data access. While SpaceX has not publicly confirmed surveillance capabilities in civilian Starlink satellites, the existence of Starshield and government contracts demonstrates clear military and intelligence applications of the technology.
