European company Arianespace has provided an update on the launch of 36 OneWeb constellation satellites from Russia’s Vostochny Cosmodrome.

On 18 December, Arianespace and its Starsem affiliate will conduct a medium-lift Soyuz 2-1b launch with the satellites into low-Earth orbit.

Flight ST29 is the designated Arianespace’s launcher family numbering system for the mission.

RUAG Space-developed Flight ST29’s dispenser system, which is filled with the satellites cluster, has been installed on its re-ignitable Fregat upper stage.

The mission will last less than three hours, 52 minutes, and will release the satellite passengers in nine deployment sequences.

The OneWeb satellites will be delivered into a near-polar orbit at an altitude of 450km.
