Ракета Ariane 5 успешно вывела спутники связи на орбиту Земли
ПАРИЖ, 29 июня. /ТАСС/. Тяжелая ракета-носитель Европейского космического агентства Ariane 5, стартовавшая в ночь на четверг с космодрома в Гвианском космическом центре (ГКЦ), успешно вывела два спутника связи на орбиту Земли. Прямую трансляцию на своем сайте вела компания Arianespace, обслуживающая запуски из Французской Гвианы.
Новая миссия стала для Arianespace седьмой по счету с начала 2017 года. "Этот старт является восьмидесятым успешным запуском Ariane 5 за 14 лет", - говорится в заявлении главы Arianespace Стефана Израэля. Спутники были выведены на орбиту спустя 39 минут после старта ракеты с космодрома.
Первый из них - GSAT-17 - принадлежит Индийской организации космических исследований (ISRO). Он предназначен для предоставления телекоммуникационных услуг на территории Индии. Его стартовая масса составляла почти 3,5 тонны. Ожидаемый срок службы - 15 лет.
На спутник установлены транспондеры для предоставления услуг телевещания и VSAT. Кроме того, на аппарате размещено оборудование для мобильной спутниковой связи, а также транспондер для ретрансляции данных и обеспечения поисково- спасательных операций. Контракт на его запуск с Arianespace был подписан в ноябре 2015 года.
Второй спутник связи, выведенный на орбиту, - Hellas Sat 3/Inmarsat S EAN. Он находится в собственности британского оператора Inmarsat и греческой компании Hellas-Sat. Он предназначен для предоставления телекоммуникационных услуг для стран Европы, Среднего Востока и Африки.
Изначально запуск этого аппарата планировался ракетой-носителем Falcon Heavy компании SpaceX. Однако из-за неготовности ракеты для запуска спутника в необходимые сроки было принято решение о переносе его на Ariane 5. Контракт с Arianespace был подписан в декабре 2016 года.

Inmarsat confirms successful launch of S-band satellite for the European Aviation Network

29 June 2017: Inmarsat (LON: ISAT), the world's leading provider of global mobile satellite communications, has confirmed the successful launch of its S-band satellite (Inmarsat S EAN) for the European Aviation Network (EAN). The launch is a key milestone for Inmarsat's unique EAN service, which is on course to commence commercial service in the second half of 2017.

The Inmarsat S-band satellite, built by France's Thales Alenia Space, was launched on an Ariane 5 rocket by Arianespace at 22:15 BST/17:15 EDT from Kourou in French Guiana. Following satellite separation at 22:43 BST/17:43 EDT, telemetry from the satellite was acquired by Inmarsat's Mingenew Ground Station in Western Australia at 22:50 BST/17:50 EDT.

The launch team from Inmarsat and Thales Alenia Space will now raise the satellite into its geostationary orbit over Europe and the Middle East, at which point the spacecraft will deploy its solar arrays and reflectors, and undergo rigorous payload testing.

Спойлер

Inmarsat's EAN is the world's first dedicated aviation connectivity solution to integrate space-based and ground-based networks to deliver a seamless WiFi experience for airline passengers throughout Europe.  Inmarsat's strategic partner, Deutsche Telekom, is well advanced in the construction of the complementary ground network, which will be fully integrated with the S-band satellite to deliver a truly seamless service for Europe's airlines and their passengers.

International Airlines Group (IAG), which includes world renowned airline brands such as British Airways, Iberia, Aer Lingus and Vueling, is confirmed as the launch customer for the new service. IAG has begun equipping its aircraft and aims to have 90% of its short haul fleet complete by early 2019.

The successful launch of the S-band satellite underlines the momentum that Inmarsat is building in the high-speed broadband inflight connectivity (IFC) market, which Inmarsat entered in October 2016 with the commercial introduction of GX Aviation, a worldwide service powered by its Ka-band, Global Xpress (Ka) satellite constellation.

Inmarsat now has over 1,200 aircraft installations expected under signed contracts for its IFC services. Mandates have been won from leading airlines worldwide including Avianca, Qatar Airways, Deutsche Lufthansa Group, International Airlines Group, Air New Zealand, Singapore Airlines and Norwegian Air Shuttle.

"Inmarsat and its partners have been making very strong progress in the IFC market and the successful launch of our S-band satellite means that the start of our revolutionary European Aviation Network is now just months away," said Rupert Pearce, CEO, Inmarsat.

"We first announced our plans for EAN in 2014, seeking to take advantage of a visionary and unique commercial and technological opportunity created by the European Commission's DG CONNECT and subsequently supported by Member State telecoms regulators.  It is a testament to the continued support of European Institutions and national regulatory authorities, the hard work of multiple teams across Inmarsat and the commitment of our vital strategic partners, including Deutsche Telekom, Thales Alenia Space, Thales Aviation, Cobham and Arianespace, that we now stand on the threshold of a new aviation WiFi service that will transform the experience of passengers flying throughout Europe.

"Although Inmarsat is a relatively new entrant into the high-speed aviation passenger broadband market, we have secured commitments for our IFC services from major airlines in Europe and across the world.  Their confidence underlines the strength of Inmarsat's IFC strategy and the long-term, scalable capabilities of our two core IFC networks – GX Aviation and EAN.   We are focused on delivering the most reliable, seamless connectivity services to airlines and remain the only major provider to deliver guaranteed performance commitments."

Hellas Sat 3 / Inmarsat S European Aviation Network (EAN) communication satellite has been successfully launched

| 29.06.2017 |

Cannes, June 29, 2017 – Hellas Sat 3 / Inmarsat S EAN telecommunication satellite, has been successfully launched by Arianespace on board an Ariane 5 rocket from Kourou launch pad in French Guiana. This condominium satellite for Inmarsat and Hellas Sat (an Arabsat subsidiary) will provide Mobile Satellite Services (MSS), Fixed Satellite Services (FSS) and Broadcast Satellite Services (BSS).

Спойлер

The Inmarsat S EAN payload will deliver communication services in the S-band to support Inmarsat's European Aviation Network, an integrated satellite and ground network that will deliver robust, high capacity inflight broadband for airline passengers across Europe.

The Hellas-Sat 3 payload will deliver in-orbit backed up DTH and Telecom services in its designated coverage areas, maintaining and expanding Hellas-Sat business reach with additional capacities and bringing video content in High Definition and Ultra High Definition format to the covered regions. The FSS/BSS coverage zones are Europe, Middle East and Sub Saharan African countries, including a cross trap service between Europe and South Africa.

"With the launch of Hellas Sat 3 / Inmarsat S EAN, Thales Alenia Space is delighted to support Inmarsat and Hellas Sat expanding their respective service offerings. We are now focused on orbital positioning operations for this satellite, the 24th built by our company to be launched in 2017" said Bertrand Maureau, EVP Telecommunications at Thales Alenia Space.

Built on the Spacebus 4000 C4 platform from Thales Alenia Space, Hellas Sat 3 / Inmarsat S EAN  will deliver a S-band multi-beam mission for Inmarsat, as well as a powerful Ku/Ka-mission of 47 Ku-transponders (Beginning of Life), 44 Ku-transponders (End of Life) and 1 Ka-transponder for Hellas Sat. Satellite launch mass is around 5.8 tons, with a Payload power around 12.7kW. It will be positioned at 39° East.
