Russia’s Starlink Rival Now Provides Stable Coverage Over Ukraine

A Russian satellite network designed to rival Starlink has reached a critical operational threshold over Ukraine, providing at least two reliable connectivity windows daily, each lasting over an hour, according to satellite communications expert Volodymyr Stepanets, as reported by Militarnyi.

Rassvet Constellation Deployment and Orbital Coverage

The Rassvet network is built by Bureau 1440, an aerospace company founded in 2020 as an internal research unit inside telecommunications giant MegaFon before spinning off under ICS Holding. Bureau 1440 launched the first operational batch of 16 Rassvet satellites on March 23, 2026, using a rocket from the Plesetsk cosmodrome, located about 200 kilometers south of Arkhangelsk. By July 31, 2026, twelve of those satellites reached their intended 550-kilometer orbit, three were still climbing, and one was lost due to a likely manufacturing defect. According to Stepanets, the satellites form a chain providing heavy coverage twice daily, with passes occurring roughly every ninety minutes.

Operational Windows for Russian Drone and Missile Guidance

Tracking data indicates the satellite group passes within range of Ukraine four times daily, though only two or three of those passes feature an elevation high enough to maintain a stable connection with ground terminals. Each usable pass lasts between an hour and ninety minutes, creating what analysts describe as communication windows. During these periods, Russian forces could theoretically utilize satellite terminals to direct maritime drones, heavy strike vehicles, and reconnaissance systems built on the Geran-2, Geran-3, and Geran-4 platforms, which are domestic Russian variants of Iranian Shahed-type drones. Defence reports that Bureau 1440 has finished developing the base version of its terminal and is preparing for serial production, potentially expanding usage from ground vehicles and command posts to cruise missiles and gliding bombs.

Launch Secrecy and Security at Plesetsk Cosmodrome

On July 19, 2026, Russia launched a second batch of 16 Rassvet satellites from Plesetsk following an information campaign designed to obscure the exact launch date. Russian authorities issued vague, repeatedly revised aviation and marine warnings starting July 10 to prevent external observers from determining the trajectory or payload. Dutch researcher Bart Hendricks linked this secrecy to Ukrainian drone activity near Plesetsk that began in December 2025 during the launch of Obzor-R. Roscosmos head Dmitry Bakanov informed Russian President Vladimir Putin that Ukrainian forces attempted a drone strike against Plesetsk during the March launch of the first batch, noting severe intrusion attempts at the spaceport.

Future Deployment Timeline and Strategic Implications

Bureau 1440 states that commercial Rassvet operations will begin in 2027, with past plans targeting 250 satellites by 2027, 730 by 2030, and over 900 by 2035. Achieving this requires launching roughly 16 satellites every month, a pace the company has not yet matched, given the four-month gap between the first two batches. Even at this slower cadence, Russia could launch a fourth batch by March 2027 and achieve round-the-clock coverage over Ukraine by the middle of that summer. This trajectory leaves Ukrainian armed forces a narrowing window to deploy effective jamming or counter-measures before the constellation completely fills its coverage gaps.

Frequently Asked Questions

What is the Rassvet satellite network?

Rassvet is a Russian satellite constellation built by Bureau 1440.

How large are the Rassvet user terminals?

The subscriber terminals measure up to 60 centimeters in length and width, weigh less than 15 kilograms, and use active phased array antenna technology to maintain connections without mechanical steering.

When is full coverage over Ukraine expected?

Analysts project that if current launch cadences continue, Russia could achieve continuous, round-the-clock coverage over Ukraine by the middle of the summer in 2027.
