Arianespace Flight ST37 - OneWeb (EN)

Flight ST37, performed by Arianespace and its Starsem affiliate from the Baikonur Cosmodrome on December 27 at 06:10 p.m. local time (01:10 p.m. UTC), will put 36 of OneWebs satellites into a near-polar orbit at an altitude of 450 kilometers. The mission will have a total duration of 3 hours and 45 minutes and will include nine separations of four satellites each, which will raise themselves to their operational orbit.

This twelfth launch for OneWeb, the eighth in 2021 alone will deploy 60% of the OneWeb constellation, thus marking the flexibility and dedication of all the teams involved in the project.

OneWebs constellation will deliver high-speed, low-latency connectivity services to a wide range of customer sectors including aviation, maritime, backhaul services, as well as governments, emergency response services and more. Central to its purpose, OneWeb seeks to bring connectivity to every place where fiber cannot reach, and thereby bridge the digital divide.

Once deployed, the OneWeb constellation will work with user terminals that are capable of offering 3G, LTE, 5G and Wi-Fi coverage, providing high-speed access globally by air, sea and land.

OneWeb Satellites, a joint venture between OneWeb and Airbus Defence and Space, is the constellations prime contractor. The satellites were built thanks to its leading-edge satellite manufacturing process that can build up to two satellites a day on a series production line dedicated to the assembly, integration, and testing of the satellites.

Arianespace offers proven launch solutions, fully adapted to the requirements of constellations and validated by the market. The 36 OneWeb satellites on Flight ST37 will be the 525th to 560th constellation satellites launched by Arianespace.

The launch of the satellites was operated by Arianespace and its Euro-Russian affiliate Starsem under contract with Glavkosmos, a subsidiary of Roscosmos, the Russian space agency. Arianespace is responsible for the overall mission and flight-worthiness, with the support of Starsem for launch campaign activities including management of its own launch facilities at the Baikonur Cosmodrome.

RKTs-Progress (the Samara Space Center) is responsible for the design, development, manufacture and integration of the Soyuz launch vehicle as well as for the 3-stage Soyuz flight. NPO Lavotchkin is responsible for the launch preparation operations and flight of the Fregat orbital vehicle.
