Flight ST27: Arianespace at OneWeb’s service for the second time


For its second mission of the year — and the initial flight in 2020 with the Soyuz medium-lift launcher — Arianespace will perform the second launch for OneWeb’s global constellation, orbiting 34 satellites.

This 50th Soyuz mission conducted by Arianespace and its Starsem affiliate will be operated from the Baikonur Cosmodrome. It will pave the way for the constellation’s deployment phase – for which Arianespace is to perform 19 more medium-lift Soyuz launches from three spaceports (Kourou, Baikonur and Vostochny) during 2020 and 2021, without mentioning the Ariane 62 maiden flight.

By operating this second flight on behalf of the global communications company OneWeb, Arianespace participates in the fulfilment of its customer’s ultimate ambition: providing internet access for everyone, everywhere.

Flight ST27 will be performed from the Soyuz Launch Complex in Baikonur, Kazakhstan.

Flight ST27, the 27th Soyuz commercial mission from the Baikonur Cosmodrome performed by Arianespace and its Starsem affiliate, will put 34 OneWeb satellites into a near polar orbit at an altitude of 450 kilometers. After separation, the satellites will raise themselves to their operational orbit.

The initial six OneWeb satellites were successfully orbited by Arianespace on Soyuz Flight VS21 from French Guiana, on February 27, 2019.

OneWeb’s mission is to deliver global communications through a next-generation satellite constellation that will bring seamless, high-speed connectivity to everyone, everywhere.

To achieve its purpose, OneWeb is building a network composed of Low-Earth Orbit satellites that will provide high-speed, low latency services to a wide range of customers in sectors that include aviation, maritime, enterprise, backhaul services, community Wi-Fi, government, emergency response services and more. Central to its mission, OneWeb’s network will enable connecting schools and bridging the digital divide for people everywhere.

Once deployed, the OneWeb constellation will enable user terminals capable of offering 3G, LTE, 5G and Wi-Fi coverage, providing high-speed, low latency government and enterprise grade broadband around the world with no barriers to connectivity in the air, by sea or anywhere on land.

OneWeb Satellites – a joint venture between OneWeb and Airbus Defence and Space – is the constellation’s prime contractor. The OneWeb spacecraft for Flight ST27 were built in OneWeb Satellites’ Florida-based series production line dedicated to the assembly, integration, and test of the OneWeb satellites. They will be the 7th to 40th OneWeb satellites to be launched by Arianespace
