European security and satellite-industry officials are warning that Russian “inspector” satellites Luch-1 and Luch-2 have been conducting sustained proximity operations in geostationary orbit (GEO) near high-value European government and commercial communications satellites, raising concerns about signals intelligence collection, surveillance, and potential interference. Reporting based on orbital tracking data indicates Luch-2 has approached or “visited” at least 17 GEO satellites serving Europe since its 2023 launch, with activity focused on operators tied to NATO countries; analysts assess that by positioning within uplink/downlink beam paths, a nearby spacecraft could potentially capture transmitted signals or at minimum characterize usage patterns and emissions.
Satellite-tracking firms cited in the reporting (including Slingshot Aerospace and France-based Aldoria) describe the Luch vehicles as maneuvering and “parking” close to target satellites for months at a time; one example given is Luch-2 operating in proximity to Intelsat 39. Beyond passive collection, observers note the same maneuvering and thruster capabilities could support more aggressive actions (e.g., nudging a satellite out of alignment), and that intelligence derived from monitoring could enable follow-on ground-based jamming or hacking by identifying users and locating ground terminals. Analysts also point to Russia expanding similar reconnaissance capabilities with newer satellites (e.g., Cosmos 2589 and Cosmos 2590), while suggesting Luch-1 may no longer be functional based on recent observations.

TTPs, infrastructure, and targeting history in one profile.
6 events from the most recent confirmed update back to the earliest known activity.
An IISS report cited by The Guardian alleged that Russia used hundreds of drones launched from shadow-fleet vessels to surveil nuclear facilities, military bases, and other strategic infrastructure across more than 12 European countries. The report said over 140 drones were observed near sensitive sites, exposing NATO air-defense gaps against low-cost, low-altitude drones.
In response to the reported Russian satellite activity, governments and satellite operators increased space domain awareness efforts, discussed norms for proximity operations, and considered technical defenses such as stronger encryption, adaptive antennas, and more resilient LEO architectures.
UK Space Command reported ongoing jamming attempts targeting British military satellites, underscoring broader concerns about Russian counterspace activity beyond surveillance.
European security officials concluded that communications from more than a dozen European satellites may have been intercepted during sustained Russian proximity operations involving Luch-1 and Luch-2.
Since its March 2023 launch, orbital tracking data indicated Luch-2 approached at least 17 European government and commercial communications satellites in geostationary orbit.
Russian inspector satellite Luch-2 was launched in March 2023 and later became the focus of European security concerns over close-proximity operations in GEO.
