Russia’s Rassvet satellites provide regular communications windows over Ukraine, report says

What happened

Ukraine’s Militarnyi defense outlet reported on August 1 that Russia’s Rassvet satellites, manufactured by Bureau 1440, provide at least two daily communications windows over Ukraine, each lasting more than an hour. The report cites satellite communications expert Volodymyr Stepanets, who analyzed the satellites’ trajectories to reach this conclusion.

Outside Brief is treating this as a source-led account. Any disputed responsibility, casualty figure, battlefield claim or single-source assertion should be treated as unconfirmed/hearsay unless confirmed by another reliable source or a named official. During these communication windows, Russian forces could theoretically use satellite terminals to control naval drones and support heavy strike and reconnaissance drones based on the Geran-2, Geran-3, and Geran-4 series, according to the report. Militarnyi noted that as of July 31, 2026, twelve out of sixteen Rassvet satellites had reached operational altitude (550 km), with three additional satellites still being positioned and one satellite lost due to a likely defect.

Stepanets described the constellation as having formed an operational formation in orbit, allowing about twice-daily broad coverage over Ukraine. However, the satellites’ orbits only provide line of sight to Ukraine four times daily, and only two or three passes reach a sufficient altitude above the horizon to sustain stable communications with ground terminals. Bureau 1440 announced a second launch group on July 20, moving the project closer to full deployment.

Known from the source

• Rassvet satellites are manufactured by Bureau 1440.
• There are currently sixteen Rassvet satellites, with twelve at operational altitude, three in deployment, and one lost.
• The satellites orbit at approximately 550 km altitude.
• The satellites provide at least two daily communications windows over Ukraine lasting more than an hour each, according to Militarnyi citing Volodymyr Stepanets.
• Bureau 1440 announced a second group of Rassvet satellites launched on July 20, 2026.

What remains unclear

Military expert and presidential adviser Serhii Beskrestnov (call sign Flash), cited by Militarnyi, estimated Russia would require 200 to 250 satellites to achieve stable communications for military purposes. He said Russia could in theory operate satellite internet terminals on Shahed drones during satellite passes but viewed this as complex and unlikely without a larger constellation. Flash added that Ukraine would likely detect any active military use through satellite traffic monitoring, intelligence sources, or captured equipment.

What remains unclear: Confirm whether the central claim is corroborated; until then treat it as unconfirmed/hearsay. The precise operational status of the Rassvet satellites’ communications capability as of the current date. Independent confirmation of the satellites’ use for drone control or military communications. Verification of technical assessments about coverage density and communications windows.
