Ukraine’s First UASAT Constellation Set to Reach 300 Satellites

Ukraine’s planned UASAT LEO communications satellite constellation will comprise 300 spacecraft, according to Militarnyi on March 11.

The report summarized that the Ukrainian project is being developed within the UASAT program as a low-Earth-orbit network.

It is intended to provide a protected communications infrastructure for government agencies, security services, and the military rather than operate as a commercial rival to global consumer satellite services.

The network is planned to operate at an altitude of about 550 kilometers. STETMAN, the company behind the project, has also outlined plans to build ground infrastructure, increase terminal production, and gradually localize satellite manufacturing in Ukraine after an initial production stage abroad.

UASAT is a Ukrainian satellite communications company and brand that positions itself as building a national satellite infrastructure, from terminals and connectivity services to its own future satellites.

For now, Ukraine’s UASAT GEO satellite terminals can maintain communications when Starlink is unavailable and are resistant to electronic warfare disruption.

The terminals use the Hughes JUPITER 3 DVB-S2X platform in the Ka-band. Download speeds can reach 100 Mbit/s, while upload speeds range from 5 to 10 Mbit/s, depending on the tariff.

UASAT also states that its terminals are compatible with the Starlink and OneWeb platforms.

So, in simple terms, UASAT currently combines its own hardware and network products with access to third-party satellite systems, while separately developing its own UASAT LEO constellation.

For the LEO system to work, Ukraine launched the ITU regulatory process for the UASAT-NANO low-Earth-orbit satellite network, led by STETMAN, after filings in December 2025 appeared in the BR IFIC Space bulletin on February 17. 

STETMAN said initial deployment is planned to begin in 2026 with 120 satellites, expanding annually, to build a protected communications system for government, security services, and military users rather than a commercial service. 

Founder Dmytro Stetsenko said the first UASAT-NANO test satellite is scheduled for launch in October 2026, with serial launches planned with SpaceX and early manufacturing supported by Denmark’s GomSpace before gradual localization in Ukraine.
