On 1 February 2018, an hour after Souyz-2.1a lift-off, Fregat Upper Stage deployed the primary payload- Earth observation Kanopus-V  satellites (No.3 and No.4) – in their design orbits. The satellites’ separation was nominal and took place at  6:06 and 6:12 Moscow time respectively in a sun-synchronous orbit.

Upon Kanopus-V separation from the Upper Stage, the Main Operations Control Group in the Mission Control Center took up their flight control. The satellites will soon be commissioned and will join the Kanopus-V constellation that includes on-orbit  Kanopus-V No.1 and Kanopus-V-IK spacecraft.

The S-Net, Lemur and D-Star One smallsats piggybacked under Glavkosmos contracts, separated nominally from  07:33 till 07:50 Moscow time. All the used ROSCOSMOS vehicles – Soyuz-2.1a launcher (by Progress Space Rocket Center) and Fregat Upper Stage (by Lavochkin Association) – performed properly.  Further smallsats’ control will be taken by the launch customers.

At the end of Fregat flight, it will be disposed and sunk in the navigation-free Pacific area.  Its reentry is programmed to occur at the altitude of 100m at about 10:34 Moscow time.


The S-NET constellation is to demonstrate an inter-satellite communication technology within a dedicated network of the four nanosatellites. The S-NET satellites’ builder and end user is Berlin Technical University.

The LEMUR mission provides global ship tracking through the Automatic Identification System (AIS) signals, weather monitoring using  GPS-RO instruments, and peaceful aircraft tracking based on  an ADS-B terminal. The satellites are built and will be used by SpireGlobal Inc. (USA).

D-Star One mission is to demonstrate and verify a new satellite platform equipped with a transmitter for D-Star radio amateur service. German Orbital Systems GmbH is the manufacture and owner of the satellite.
