Flight ST31: Arianespace to serve OneWeb’s ambitions with 36 more satellites to be launched
The next Arianespace mission is planned from Vostochny Cosmodrome with Soyuz on April 26, to deliver 36 satellites into orbit.
By operating this fifth flight on behalf of OneWeb, Arianespace will bring the total fleet to 182 satellites in Low Earth Orbit. Arianespace is proud to share in the fulfilment of its customer’s ultimate ambition: providing internet access for everyone, everywhere.
Flight ST31, the third commercial mission performed by Arianespace and its Starsem affiliate from the Vostochny Cosmodrome, will put 36 of OneWeb’s satellites into a near-polar orbit at an altitude of 450 kilometers. The mission will have a total duration of three hours and 51 minutes and will include nine separations of four satellites, that will raise themselves to their operational orbit. This sixth launch to the benefit of OneWeb will bring up to speed Arianespace’s operations this year, and will raise from 146 to 182 the number of satellites deployed for the global telecommunications operator.
OneWeb’s mission is to bring internet everywhere to everyone, by creating a global connectivity platform through a next generation satellite constellation in low Earth orbit. OneWeb’s 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 enable 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 constellation’s 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 uses space to make life better on Earth by providing launch services for all types of satellites into all orbits. It has orbited almost 800 satellites since 1980, using its family of three launchers, Ariane, Soyuz and Vega, from launch sites in French Guiana (South America) and from the Russian cosmodromes in Baikonur and Vostochny. Arianespace is headquartered in Evry, near Paris, and has a technical facility at the Guiana Space Center in French Guiana, plus local offices in Washington, D.C., Tokyo and Singapore. Arianespace is a subsidiary of ArianeGroup, which holds 74% of its share capital, with the balance held by 15 other shareholders from the European launcher industry.
Starsem is dedicated to providing international commercial marketing and operation of the Soyuz launch vehicle from the Baikonur cosmodrome. Shareholders in Starsem are Arianespace, ArianeGroup, the State Space Corporation ROSCOSMOS and the Samara Space Center “RKTs-Progress”. www.starsem.com
