On December 27, 2018, the Soyuz-2.1a launch vehicle with the Fregat upper stage, Kanopus-V-5/6 Earth remote sensing spacecraft and 26 piggyback satellites successfully blasted off from the Vostochny cosmodrome. It was the fourth launch performed from Vostochny, the first Russian civil cosmodrome.
In accordance with the flight program, the Fregat upper stage injected primary and piggyback payload satellites into a low earth orbit. On completion of the flight program, the Fregat upper stage re-entered the atmosphere at an altitude of 100 km at about 10:25 Moscow time and splashed down in a non-navigable region of the Pacific Ocean.
The ECM SmallSat Cluster comprises the D-Star ONE (iSat), D-Star ONE (Sparrow), UWE-4, eight Lemur satellites and the GRUS, launched as secondary payloads under contracts with JSC Glavkosmos, were successfully separated from the Fregat upper stage in orbits with an altitude of approximately 585 kilometers from 07:33 to 07:50 Moscow time.
The Lume-1, ZACube-2 and twelve Dove satellites, launched under contracts with GK Launch Services, were also successfully separated from the Fregat upper stage in orbits at an altitude of approximately 495 kilometers from 09:13 to 09:43 Moscow time.
Further on, smallsats will be operated by the launch customers.
