Mission Details
OneWeb #17
The 17th flight dedicated to the OneWeb high-speed Internet constellation. The initial constellation consists of 648 satellites. Later, the constellation could be expanded to more than 900 satellites depending on demand. OneWeb is expected to begin customer demonstrations in 2022, then provide a global, 24-hour service in 2022/2023.
Each satellite in the constellation weighs 147.7 kg. They are powered by Russian ion engines, manufactured by OKB-Fakel, and have two solar panels for their power supply. The first generation of satellites, operating on a quasi-polar orbit (1 200 km x 86.4°), cannot perform inter-satellite communication, and can only be used near a ground relay station.
The satellites will provide user service in the Ku-band, communicating in the microwave range of frequencies in the 12-18 GHz portion of the electromagnetic spectrum.
The satellites use a technique called "progressive pitch" in which the satellites are slightly turned to avoid interference with Ku-band satellites in geostationary orbit. The user terminal antenna on the ground will be a phased array antenna measuring approximately 36 by 16 cm and will provide Internet access at 50 megabits/second downlink bandwidth (almost certainly less uplink, but this number remains hard to pin down). The satellites will be designed to comply with orbital debris-mitigation guidelines for removing satellites from orbit and, for low-orbit satellites, assuring that they reenter the Earth's atmosphere within 25 years of retirement.
Payloads: 36   Total Mass: 5,317 kg   Polar Orbit

OneWeb  @OneWeb
An exciting update from our team in India as we confirm the successful integration of our 36 satellites ahead of our upcoming launch with @ISRO and @NSIL_India.
Thanks to our team working on site as we mark another step closer to completing the OneWeb global constellation

Подпись к фотографии ( специально <удалено>).

OneWeb готовится к предстоящему запуску (OW18) в Индии в марте с острова Шрихарикота. ISRO будет использовать свою самую мощную ракету-носитель GSLV-MkIII.
36 спутников прибыли в Космический центр имени Сатиша Дхавана (SDSC- SHAR) 24 января 2023 года, были подготовлены и интегрированы на диспенсере Beyond Gravity, таком же, который используется на "Союзе".
Тот же диспенсер, та же команда ARIANESPACE для реализации и интеграции 36 спутников OneWeb.
Это второй раз, когда ARIANESPACE участвует в проекте в Индии после OW14.
На этой фотографии **5 Arianespace ** одеты в белую форму с синим логотипом AE на правой стороне.

И добавлю от себя. Двое из команды работали по Союзу на Байконуре и Куру с конца 90-х.

Launch of LVM3-M3/OneWeb India-2 Mission from Satish Dhawan Space Centre (SDSC) SHAR, Sriharikota
  ISRO Official
The launch of LVM3-M3/OneWeb India-2 mission is scheduled for March 26, 2023, at 0900 hours IST from the second launch pad at Satish Dhawan Space Centre SDSC-SHAR, Sriharikota.
This is the second mission for M/s. Network Access Associates Limited, United Kingdom (OneWeb Group Company) under a commercial agreement with M/s. NewSpace India Limited (NSIL) to launch 72 satellites to Low-Earth Orbits. The first set of 36 satellites was launched in LVM3-M2/OneWeb India-1 mission on October 23, 2022.
In this mission, LVM3 would place 36 OneWeb Gen-1 satellites totaling about 5,805 kg into a 450 km circular orbit with an inclination of 87.4 degrees. This is the sixth flight of LVM3. The LVM3 had five consecutive successful missions, including the Chandrayaan-2 mission.
