Russia's Rassvet low‑Earth‑orbit satellite programme now reaches Ukrainian airspace for two short windows each day, according to a Ukrainian defence‑technology site. Each window lasts roughly one to one and a half hours, offering intermittent high‑speed data links that could be used by Russian forces for command, control and unmanned‑system guidance.

Launch cadence and constellation size

Since 2023 the programme has placed twenty‑one satellites in orbit, as recorded by the Satellitemap database. The first batch of sixteen satellites was launched in March 2024, followed by a second batch of sixteen in July 2024. A further sixteen are scheduled for launch in the autumn, with windows projected for October or November. Analysts note that the current constellation is far short of the two hundred to two hundred fifty satellites required for continuous, stable coverage.

SpaceX's Starlink constellation, with roughly eleven thousand satellites, already provides near‑global broadband connectivity and is the main communications backbone for Ukrainian forces, including guidance of Hornet attack drones. By contrast, the Rassvet system is intended to give the Kremlin an independent high‑speed link for the military, remote Arctic regions and occupied territories, reducing reliance on Western services.

Military implications

If portable ground terminals can lock onto Rassvet signals, Russian units could attach real‑time data links to loitering munitions such as the Geran drone, potentially eliminating the need for signal‑boosting equipment in neighbouring Belarus. State media channel Two Majors describes a vision of a unified network that would connect reconnaissance platforms, radar stations and artillery crews, delivering live battlefield intelligence across the front line.

At present the satellite chain offers only two daily passes over Ukraine, with the possibility of additional passes depending on orbital geometry and the availability of ground terminals. Experts stress that the intermittent nature of the links limits their usefulness for sustained command and control, and that continuous coverage would likely not be achievable until early 2028 if the current launch rhythm is maintained.

European security and counter‑measures

The emergence of a Russian sovereign satellite network raises concerns for European defence planners. A system that can be activated over contested areas could shift the electronic‑warfare balance, especially if coverage expands into the Arctic where many NATO early‑warning radars are located. EU member states hosting NATO radar sites may need to reassess the vulnerability of their communications infrastructure.

Analysts suggest that kinetic anti‑satellite strikes would create hazardous debris, threatening other space assets. More practical options include jamming the signal, disabling ground gateways or blocking terminals, with fewer than ten ground stations potentially sufficient to cripple the network at relatively low cost. These ideas align with broader EU initiatives to build resilient satellite‑communication capabilities and protect critical infrastructure from hostile interference.

Future trajectory

Russian officials have set a long‑term goal of about one thousand Rassvet satellites by 2035. Maintaining the current cadence of roughly one batch every three months would place a fourth batch in orbit by March 2027, but a faster launch rate would be required to meet the 2035 target. Continuous coverage over Ukraine could become possible by early 2028, at which point the network could support coordinated artillery fire, unmanned‑system guidance and secure links with forces in occupied Donbas cities.

The development of Rassvet reflects a wider great‑power competition in low‑Earth orbit, mirroring China's Hongyun constellation and US Space Development Agency projects. Russian officials describe the programme as a safeguard against Western digital hegemony and argue that a domestic system is necessary for sovereignty. Critics contend that the resources devoted to a parallel satellite network could be redirected to domestic priorities such as modernising the power grid, expanding broadband in remote Russian regions or alleviating economic hardships.

For workers in the EU the story highlights the growing role of satellite services in remote work and telemedicine, underscoring the need for regulatory frameworks that protect consumers and ensure infrastructure resilience. Both Kyiv and Brussels are monitoring the Rassvet constellation's growth to determine whether it remains an experimental tool or evolves into a full‑scale communications platform capable of influencing warfare and European security.
