Buro 1440 unveils Rassvet-4 satellite constellation project

Buro 1440 has announced plans to deploy a new generation of satellite internet systems named Rassvet-4. A formal application for a constellation of 374 satellites has been submitted to the International Telecommunication Union (ITU).

• The project consists of 374 satellites across 17 orbital planes.
• Operational altitude is set at approximately 800 km.
• Each satellite features 12 antenna beams for transmission and reception.
• The new generation is designed to supplement and eventually replace the current Rassvet-3 system.

Orbital Architecture The proposed configuration distributes 22 satellites into each of the 17 orbital planes. This design signifies a major scalability upgrade over the current Rassvet-3 system, which has only deployed 32 satellites as of late 2026. The new constellation aims to create a robust and continuous network architecture.

Technical Specifications According to the ITU filing, each Rassvet-4 unit is equipped with 12 antenna beams: seven for transmission and five for reception. While specific details regarding satellite weight and power capacity remain undisclosed, the integration of new beam parameters suggests significant improvements over the preceding technology.

Implications for Global Connectivity The Rassvet-4 initiative represents a strategic move towards building a sovereign high-speed satellite internet infrastructure. By scaling up the constellation, Buro 1440 aims to bridge connectivity gaps in remote and underserved areas, aiming to provide a reliable alternative to existing global satellite systems.
