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.

Any precision in the deploy time for these batches (three and nine)? Maybe ~20:57 and ~21:52 UTC so that they fit 'nicely' with the other seven?

With Flight ST35 for OneWeb, Arianespace sets a new mark by successfully putting more than 1,000 satellites in orbit since its foundation

- Soyuz Flight ST35 placed 34 more satellites into orbit. Following this 10th launch for OneWeb, Arianespace has deployed 322 satellites for the global connectivity constellation.

– Ninth successful launches and sixth Soyuz operated by Arianespace and Starsem since the start of the year.

– With this launch, Arianespace will have deployed 1,021 satellite since its incorporation in 1980.

Performed on Tuesday, September 14, at precisely 11:07 p.m. local time at Russia’s Baikonur Cosmodrome (06:07 p.m. UTC), Soyuz Flight ST35 lifted-off with 34 OneWeb satellites onboard, bringing, after the successful deployment, the size of the fleet in orbit to 322. Flight ST35 was the 60th Soyuz mission carried out by Arianespace and its Starsem affiliate, and the tenth mission to the benefit of OneWeb.

The mission lasted three hours and 45 minutes. The 34 satellites were deployed during nine separation sequences, at an altitude of 450 km. It was also the ninth successful launch operated by Arianespace’s teams this year, bringing to 1,021 the total number of spacecraft orbited since the start of company’s operations.

“Congratulations to all the teams who made this 60th launch with Soyuz, the 10th for OneWeb, a success. We are living a great moment today as we pass the step of our 1,000th satellite launched to space while our customer OneWeb is hitting a new pace with more than 300 satellites in orbit. This 1,000th satellite was named XiliaSat by our community in reference of the meaning of 1,000 in ancient Greek in a contest on our social media,” said Stéphane Israël, CEO of Arianespace. “This launch illustrates the recent acceleration in space operation – one third of these 1,000 Arianespace-launched satellites orbited over the 20 past months – and thus it is incumbent upon us, as leaders in the space sector, to embrace our responsibility to promote sustainable space operations.”

To date, Arianespace has launched 322 OneWeb satellites with ten Soyuz launches. Arianespace will perform nine more Soyuz launches for OneWeb through 2021 and 2022. These launches will enable OneWeb to complete the deployment of its full global constellation (650 satellites) in low Earth orbit by year-end 2022.

OneWeb’s mission is to create a global connectivity platform through a next-generation satellite constellation in Low Earth Orbit. The OneWeb constellation will deliver high-speed, low-latency connectivity to a wide range of customer sectors, including aviation, maritime, enterprise and government. Central to its purpose, OneWeb seeks to bring connectivity to the hardest to reach places, where fiber cannot reach, and thereby bridge the digital divide.

The satellite prime contractor is OneWeb Satellites, a joint venture of OneWeb and Airbus Defence and Space. The satellites were produced in Florida, USA, in its leading-edge satellite manufacturing facilities that can build up to two satellites per day on a series production line dedicated to spacecraft assembly, integration, and testing.

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.

All 34 OneWeb satellites put into designated orbit.

The first six OneWeb satellites were orbited by a Soyuz-ST carrier rocket from the Kourou spaceport in French Guiana on February 28, 2019.

14 SEP, 16:38

MOSCOW, September 15. /TASS/. All 34 OneWeb communications satellites, launched atop a Soyuz-ST carrier rocket on Tuesday evening, have been put into the designated orbit, Russian state-run space corporation Roscosmos said in a statement released on Wednesday.

"All 34 OneWeb communications satellites successfully separated from the Fregat booster and reached their designated orbits," the statement says.

It was the 100th mission for Russia’s Fregat booster. After completing its mission, the booster will be de-orbited and sunk in non-navigational area of the Pacific Ocean.

The Soyuz-2.1b carrier rocket was launched from the Baikonur space center in Kazakhstan at 21:07 Moscow time on Tuesday. The launch is to bring the number of British satellites to 322.

The first six OneWeb satellites were orbited by a Soyuz-ST carrier rocket from the Kourou spaceport in French Guiana on February 28, 2019. Another 34 satellites were delivered into outer space on February 7, 2020 and the same amount on March 21 from the Baikonur space center.

OneWeb satellites were launched from the Vostochny spaceport in Russia’s Far East for the first time in December 2020. A total of 36 space vehicles were put into orbit. Further launches took place from the Vostochny space center on March 25, April 26, May 28, and July 1, 2021, and from Baikonur on August 22, 2021. The next launch is scheduled for October 14 from Vostochny.

OneWeb’s renewed agreement with the French Arianespace that acts as the launch operator stipulates the lift-off of 16 Russian Soyuz carrier rockets from the Kourou, Vostochny and Baikonur launch facilities in 2020-2022. Each launch can put between 34-36 OneWeb satellites into orbit.
