Nosy neighbors in the room become a problem.
Russian ‘inspector’ satellites are once again in the spotlight after evidence emerged that two spacecraft maneuvered unusually close to crucial communications satellites in orbit, raising concerns in the wider technology and satellite industry about surveillance, signal interception and the increasing militarization of orbital infrastructure.
According to defense and intelligence sources, the satellites, known as Luch-1 and Luch-2, carry out long-duration proximity operations near European government and commercial satellites and are believed to be part of Russia’s ‘inspector’ satellite program.
Orbital tracking data shows that Luch-2 has accessed at least seventeen European satellites since its launch in March 2023. Most of this activity takes place in geostationary orbit, or GEO, the space of space about 22,000 miles (36,000 kilometers) above Earth where satellites match the planet’s rotation and remain fixed over specific regions.
Importantly, this is where some of the most valuable infrastructure in the modern tech ecosystem resides. Because GEO is the most important real estate for telecommunications, military command connections, television broadcasts, weather monitoring and secure data transmission by the government, this motion is important.
Any satellite operating nearby could theoretically detect signal patterns, monitor emissions, or even disrupt operations. So when a foreign satellite starts maneuvering nearby, operators take notice.
Signals intelligence operations in orbit
European security officials believe the Luch satellites have intercepted communications from more than a dozen satellites serving the continent. To solve this, satellites communicate with Earth via radio beams. In that process, a spacecraft is in the narrow uplink or downlink beams that connect ground stations to satellites. By positioning itself within the beam path, a spacecraft may be able to capture transmitted signals, especially if encryption protection is weak.
This type of activity falls under Signals Intelligence (SIGINT), a form of eavesdropping on electronic communications. Doing this from space provides lasting coverage and access to high-quality data streams, and healthcare is not limited to military systems. Some of the allegedly shadowed satellites are owned by commercial operators such as Intelsat, whose fleet supports both private companies and government customers.
That dual use is what worries policymakers and technology leaders alike, as modern defense operations rely heavily on commercial satellite bandwidth, cloud connectivity and relay services. Disruption of commercial satellites could have serious consequences for military operations, emergency services, aviation communications and even the timing of financial transactions.
Jamming, cybersecurity and orbital risk
Officials are also concerned about more direct interference. Satellites operating in close proximity could theoretically attempt electronic jamming, signal spoofing, or even physical disruption. Although no collisions have been reported to date, the maneuvering demonstrates capabilities that are changing the way countries view their orbital security.
UK Space Command has already reported regular jamming attempts against British military satellites. Electronic warfare in orbit typically involves injecting noise into communications links or attempting to disrupt the integrity of data transmissions.
Newer satellites are equipped with technology to counteract all of this. Frequency hopping, adaptive antennas, and stricter encryption are just a few examples of anti-jamming technology, but protection measures vary widely, especially among older commercial platforms still in use.
After all, for the broader technology industry, modern digital life depends on orbital infrastructure.
Satellite networks support cloud connectivity in remote areas, global internet coverage, GPS navigation, IoT deployments and broadcast media distribution. Even financial markets rely on satellite timing signals for transaction synchronization.
As a result, organizations are expanding radar and optical monitoring networks to better understand who is maneuvering where.
Governments and private companies are accelerating investments in space domain awareness, which involves systems that can track, map and predict satellite movements and detect suspicious maneuvers in real time. Satellite cybersecurity is being prioritized and encryption is now seen as mission-critical infrastructure protection.
At the policy level, regulators and defense alliances are beginning to discuss standards for satellite proximity operations.
What it means for the space industry
In “space” space there is also a movement toward scattered constellations in low Earth orbit. Unlike GEO systems, which rely on a limited number of high-value assets, distributed networks provide redundancy and are more difficult to disrupt.
Furthermore, this raises the question of what is really “allowed” in space, with the growing debate surrounding orbital standards and traffic regulations. Currently, there are few enforceable rules governing how close one satellite can get to another. This regulatory gap could become a bigger problem as maneuverable spacecraft become more common.
Communications infrastructure in orbit now exists at the convergence of cybersecurity, defense strategy and global connectivity. And for technology leaders and satellite operators, orbital security is now inextricably linked to cybersecurity.
