10th OneWeb launch completed

09/14/2021 21:18

Today, September 14, 2021, at 21:07:19 Moscow time, the joint crew of Roscosmos subsidiaries at the Baikonur cosmodrome launched the Soyuz-2.1b launch vehicle with the Fregat upper stage and 34 OneWeb spacecraft in within mission number 36. After 563.9 seconds, the orbital block was put into a suborbital trajectory.

According to telemetry information received at the Central Information Center, the lift contact, rocket flight, separation of stages and the orbital block were fully completed in normal mode. After that, the Fregat upper stage continued to launch 34 vehicles into the target circular orbit. Within 3.5 hours, OneWeb satellites, in accordance with a given cyclogram, will alternately separate from the Russian "accelerator", which was developed at the S.A. Lavochkin (part of the Roscosmos State Corporation).

The engines of the launch vehicle also worked in the normal mode, including the engines of the RD-107/108 family of the first and second stages, developed at the Scientific and Production Association "Energomash" named after academician V.P. Glushko (part of the Roscosmos State Corporation), and the third stage RD-0124 engine, created at the Voronezh rocket engine building center (part of the integrated rocket engine building structure headed by NPO Energomash of the Roscosmos State Corporation).

With this launch, the OneWeb low-orbit constellation will increase by 34 satellites and reach 322. This launch became the tenth one within the OneWeb program, the second from Baikonur in 2021 and the fourth from this cosmodrome as a whole. The work is being carried out under a contract between Glavkosmos (part of Roskosmos) and Arianespace and Starsem.

The Soyuz-2 launch vehicle was developed on the basis of the Soyuz-U missile. The lead developer is the Progress Rocket and Space Center (Samara, part of Roscosmos). Upgraded propulsion systems and modern control and measurement systems are used on launch vehicles of the Soyuz-2 family, which improves technical and operational characteristics.

Structurally "Soyuz-2", like all missiles of the "Soyuz" family, is made according to the scheme of longitudinal-transverse division of rocket stages. In combination with the Fregat upper stage, it is intended for launching spacecraft into low-earth orbits of various heights and inclinations, including geo-transfer and geostationary orbits, as well as departure trajectories.

Fregat's 100th flight: 322 OneWeb satellites in orbit

09/15/2021 01:53

On Tuesday, September 14, 2021, at 21:17:09 Moscow time, the Soyuz-2.1b launch vehicle with the Fregat upper stage and 34 new spacecraft of the satellite company OneWeb. This launch has already become the tenth in the framework of the joint OneWeb program.

The sequential separation of nine groups of spacecraft (in the first - two, in the rest - four satellites) from the Russian upper stage took place in accordance with the program laid down by the specialists of the S.A. Lavochkin (part of the Roscosmos State Corporation). During the autonomous flight, eleven active sites were provided: three activations of the propulsion system (the latter for the purpose of delivering the upper stage to the “withdrawal orbit”) and eight activations of the propulsion system for stabilization, orientation and launch support necessary for the safe separation of satellites.

Foreign customers of the company "Glavkosmos" (part of Roscosmos) confirmed the fulfillment of contractual obligations. All devices are accepted for communication by the customer. Upon completion of the disengagement and separation of spacecraft, the Fregat upper stage will be de-orbited, and non-combustible elements will be flooded into the uninhabited part of the Pacific Ocean.

The spacecraft were launched by order of the European provider of launch services Arianespace (spacecraft launch operator OneWeb) and by Starsem under contracts with Glavkosmos. It was carried out by the joint calculation of Roscosmos subsidiaries: the Progress Rocket and Space Center, the S.А. Lavochkin, Center for Operation of Ground-Based Space Infrastructure Facilities, Russian Space Systems, Glavkosmos, as well as foreign customers.

About the upper stage

The Upper Stage "Fregat" ensures the efficient performance of all tasks of placing one or several vehicles into working orbits or trajectories taking off from the Earth. The entire process of launching is carried out autonomously, without interference from the Earth. The highest reliability and almost perfect launch accuracy provide the upper stage with undeniable competitive advantages in the global space launch market. This launch became the 100th launch for the Fregat upper stage.

The basic upper stage "Fregat" laid the foundation for a whole family of highly efficient upper stages, which are created and are created on its basis. The use of additional fuel tanks and a dumped block of tanks ("Fregat-MT" and "Fregat-SB") on the "Fregat" made it possible to significantly increase the mass of the refueled fuel and, thereby, to increase the efficiency of the upper stage.

The basis of the structural and layout scheme of the Fregat upper stage is a block of tanks built according to a monoblock carrier scheme. It has a torispherical configuration, consisting of six spherical containers welded together, separated by spherical bottoms. Four of them are oxidizer and fuel tanks, two tanks are compartments for onboard instruments and equipment (one of them is sealed).

One of the containers (sealed) houses a monoblock of the control system, including satellite navigation equipment and fans of the thermal regime, in the other (unpressurized) - a small instrument compartment, service blocks, as well as high-pressure balloons of the cruise propulsion system and the propulsion system for stabilization, orientation and ensuring the launch.

About OneWeb satellites

OneWeb spacecraft are designed to create a space communications system that provides high-speed Internet access anywhere on Earth. Internet access via the OneWeb satellite system will be provided through 40 ground-based terminal stations that will be deployed on the surface of the Earth.

The OneWeb terminals will be self-contained, self-sufficient and well protected from adverse environmental factors. Each of them will be able to provide high-speed Internet access in its coverage area via Wi-Fi, LTE or 5G technologies. In addition, the licensed radio frequency range will be used or, where possible, the publicly available Wi-Fi, LTE or 5G radio frequency range.

The first OneWeb satellites were launched into orbit in February 2019 from the Guiana Space Center. In July 2021, the company announced that it plans to complete the deployment of a satellite constellation to provide global coverage by June 2022. According to OneWeb, the low-Earth orbit constellation will consist of 648 satellites.

OneWeb Confirms Successful Launch of 34 Satellites from Baikonur

OneWeb confirms successful launch and contact with all 34 satellites, bringing total in-orbit constellation to 322 satellites
With this launch, OneWeb constellation is almost half way complete; Arianespace celebrates 1,000+ satellites successfully deployed
OneWeb continues to gain momentum, recently announcing another series of global distribution partnerships and strategic agreements

London, 15 September 2021: OneWeb, the Low Earth Orbit (LEO) satellite communications company, today confirmed its successful launch of 34 satellites by Arianespace from the Baikonur Cosmodrome in Kazakhstan. This latest successful launch brings OneWeb’s total in-orbit constellation to 322 satellites, nearly half of OneWeb’s entire 648 LEO satellite fleet that will deliver high-speed, low-latency global connectivity.

The successful launch builds on the strategic distribution partnerships and agreements across a wide array of providers and businesses, including several earlier this month, including with AT&T, Hughes Network Systems, and Peraton. These agreements, along with others struck earlier with partners including Alaska Communications, BT, and Northwestel, are aimed at bringing improved digital communication services to some of the hardest to reach parts of the world.

Liftoff occurred on 14 September at 7:07pm BST. OneWeb’s satellites separated from the rocket and were dispensed in nine batches after 3 hours 45 minutes into the flight, with signal acquisition on all 34 satellites confirmed. With this launch, Arianespace also celebrates passing the mark of 1,000 satellites successfully launched to space.

OneWeb remains on track to start service this year at the 50th parallel and above with its constellation and to deliver global service in 2022. The company continues to see growing demand from telecommunications providers, ISPs, and governments worldwide to offer its low-latency, high-speed connectivity services to the hardest to reach places. OneWeb has raised USD $2.7 billion since November 2020, with no debt issuance.

Neil Masterson, OneWeb CEO, commented: “The team continues to stay focused on execution and delivering our network. I am enormously grateful to the team and all our partners who are making these milestones possible. We continue to see a huge and growing demand for our services from global customers, and we are incredibly excited about both introducing commercial service and scaling our global network.”
