Flight ST31: Arianespace to deliver Oneweb's ambitions with 36 more satellites for launched


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.
