Episode notes
Jamming Crippled Starlink Uplink Capacity
- Iran used military-grade jammers to degrade Starlink, driving packet loss up to 80% in Tehran and other cities.
- The attack targeted satellite uplink signals that protesters rely on to send video and information abroad.
Jamming Is Active Electronic Warfare
- Satellite jamming requires active electronic warfare and specialist gear, unlike a simple terrestrial kill switch.
- Experts suspect Iran sourced or developed the tech with help from Russia or China and adapted TV jammers for LEO constellations.
Upload Targeting Shows Tactical Purpose
- Iran focused on upload throttling to prevent protesters from sending videos abroad while leaving downloads less affected.
- SpaceX previously countered Russian jamming in Ukraine with fast software patches, creating a cat-and-mouse dynamic.
