UK Satellites Under Siege: Top Space General Warns of Russia’s “Weekly” Attacks

UK Satellites Under Siege: Top Space General Warns of Russia’s “Weekly” Attacks

Russia’s New Frontier: Satellite Warfare Senior UK officials say the war in Ukraine has spilled into space. In interviews with the BBC, Space Command chief Paul Tedman detailed how Russia regularly monitors and jams British military satellites. These jamming attacks are conducted from the ground by powerful transmitters that drown out the satellites’ signals ontheradar.csis.org portsmouth.co.uk. Crucially, jamming is non-kinetic: it disrupts data links but does not physically destroy the satellite ontheradar.csis.org. Once the interference stops, normal communications can resume. Tedman stressed that since Russia’s full-scale invasion of Ukraine, these attempts have become “persistent, deliberate, and increasingly aggressive” united24media.com. When pressed on

Space‑Laser Shockwave: Inside China’s 2‑Watt Orbital Beam That Claims to Outgun Starlink and Reshape the Security Balance in Space

In June 2025, Wu Jian of Peking University of Posts & Telecom and Liu Chao of the Chinese Academy of Sciences directed a 2-watt laser from 36,000 km in geostationary orbit to a ground station, achieving 1 Gbps. The test claimed the 1 Gbps downlink is five times faster than Starlink downlinks, per the South China Morning Post. The AO-MDR scheme combines adaptive optics and mode-diversity, routing eight spatial modes through a 1.8 m telescope and real-time selecting the three cleanest channels. Usable signal quality rose from 72% to 91% despite atmospheric turbulence thanks to AO-MDR. Starlink consumer downlinks typically
