ЦитироватьС космодрома во Французской Гвиане запустят греческий спутник
19:25  24.02.2017
 
АФИНЫ, 24 фев — РИА Новости, Геннадий Мельник. Строительство греческого спутника связи Hellas Sat 3 находится на завершающей стадии, он будет запущен 28 июня с космодрома во Французской Гвиане, сообщило министерство цифровой политики, телекоммуникацией и информации Греции.
После вывода на орбиту спутник будет контролироваться греческими инженерами на предприятии Hellas Sat в Коропи.
Новый спутник будет на 50% мощнее, чем его предшественник Hellas Sat 2, и станет самым большим европейский орбитальным спутником.
В пятницу министр цифровой политики Никос Паппас посетил французское предприятие ThalesAlenia Space в Каннах, где строится спутник. По словам министра, спутник уже прошел все испытания.
В январе Греция заявила о решении вернуться в космос — министерство цифровой политики, телекоммуникаций и информации Греции создает Греческое космическое агентство. Агентство создается в форме акционерной компании, которая будет называться "Национальный центр космической деятельности" (EKDE) и призвана заполнить пробелы в этой области.
EKDE будет заниматься арендой, на основе частных экономических критериев, имеющихся передатчиков, которые не будут использованы правительством Греции (в военной, телекоммуникационной и другой деятельности). Важное значение имеет и использование результатов научно-исследовательской и научной деятельности в космосе, например, для гражданской защиты, мониторинга Земли, предотвращения и тушения пожаров, незаконного строительства и так далее, считают в министерстве.
EKDE будет связан с основными греческими и международными научно-исследовательскими центрами, объединит исследования для греческих предприятий, облегчит использование результатов деятельности для греческой оборонной промышленности и греческой армии.
У Греции раньше был спутник, принадлежавший греческой телекоммуникационной организации OTE. Спутник Hellas Sat 2 был запущен в мае 2003 года, через него идет вещание на страны Европы, Ближнего Востока и Северной Африки. Но в 2013 году спутник продан арабской компании за 208 миллионов евро. Решение продать первый и единственный национальный спутник было неоднозначно встречено в Греции. Некоторые СМИ писали, что "немцы в ОТЕ под покровом ночи продали единственный греческий спутник и лишили страну ее собственной спутниковой связи", имея в виду, что крупнейшим акционером ОТЕ является Deutsche Telecom (ей принадлежит 40% акций).
Как ранее заявлял министр цифровой политики Никос Паппас, Греция за последние 20 лет внесла сотни миллионов евро для участия в европейских космических программах, таких, как "Галилео", но не может использовать результаты научной и исследовательской деятельности, а также ресурсы Европейского космического агентства.

Launch preparations with Soyuz, Ariane 5 and Vega keep Arianespace on track for 12 missions in 2017

Arianespace's objective of performing 12 launches in 2017 is backed by a high level of activity at the Spaceport in French Guiana, where mission preparations, payload checkout and launch vehicle hardware are in process for upcoming flights with Soyuz, Ariane 5 and Vega.
Спойлер

The basic three-stage Soyuz launcher for Flight VS17 is raised into position in the ELS launch zone, where it was fitted with the SES-15 payload and Fregat upper stage.
 
For the company's next liftoff, a medium-lift Soyuz is now in the Spaceport's ELS launch zone, fitted with its SES-15 telecommunications satellite payload. Undergoing the countdown for a morning departure on Thursday, May 18, this launch is designated Flight VS17 in Arianespace's launcher family numbering system – signifying the 17th mission with the Russian-built workhorse vehicle since it entered service at the Spaceport in 2011.
[свернуть]
Flight VS17 will mark Arianespace's fifth mission so far in 2017, following two launches with the heavy-lift Ariane 5, and one each utilizing Soyuz and the light-lift Vega.

Preparing for the next two Ariane 5 flights
Elsewhere at the Spaceport, the next Ariane 5 has moved fr om the Launcher Integration Building to the Final Assembly Building, wh ere a dual payload of the Viasat-2 and Eutelsat E172B telecommunications satellites will be integrated. This mission is designated Flight VA237, denoting the 237th flight with an Ariane launcher since the family of European-built vehicles began Spaceport operations in 1979.
Activity also has begun for the subsequent Ariane 5 launch, VA238, which will loft the Hellas-Sat 3/Inmarsat S relay satellite and the GSAT-17 telecommunications spacecraft for the Indian Space Research Organisation.

GSAT-17 arrived in French Guiana this week aboard a chartered cargo jetliner that landed at Cayenne's Félix Eboué Airport. Separately, elements for Flight VA238's Ariane 5 launch vehicle were delivered to Kourou's Pariacabo port by the MN Toucan roll-on/roll-off transport ship, completing a trans-Atlantic sea voyage that also carried launcher components for Arianespace's next Vega mission.

US$1.6bn commitment to Global Xpress
Three Global Xpress (GX) satellites – the Inmarsat-5 constellation – deliver seamless, globally available, high-speed broadband connectivity that spans the world.
Global commercial service introduction (CSI) was achieved for Global Xpress (GX) during December 2015 following the successful launch of I-5 F1 in December 2013; I-5 F2 in February 2015; and I-5 F3 in August 2015.
As part of Inmarsat's ongoing US$1.6bn programme commitment, a fourth Global Xpress satellite (I-5 F4) has completed construction and testing by Boeing in California, and is likely to be launched in mid-2017 in order to provide additional GX capacity.
GX operates in the part of the radio spectrum known as the Ka-band and is the first of its kind to offer true global mobile VSAT-type services, fr om a single operator. Market research shows there to be an estimated US$1.9 billion market opportunity in the maritime, energy and government sectors.
Global Xpress is expected to deliver no less than $500m of additional revenues by the fifth anniversary of the global launch of commercial GX services.

Connectivity for smartphones, tablets and laptops
Global Xpress delivers higher speeds through more compact terminals at a lower cost than traditional VSAT services, using spectrum that is far less congested. It enables more bandwidth-intensive video applications, alongside standard applications at a much faster speed.
Terminals will come in mobile, portable and fixed formats for our customers on land, at sea and in the air. They will support connectivity for smartphones, tablets and laptops.
It's superfast and reliable, but Global Xpress is much more than a fatter pipe.
A new platform for advanced applications
Our vision is to create a rich application and content environment. Together with Cisco, we've developed a new platform for advanced applications such as TV on demand, tele-presence and collaborative working.
And because Global Xpress is an all-IP environment, it enables point-and-click capability for a simple and consistent user experience worldwide.
For extra resilience, Global Xpress is complemented by our standard L-band broadband services on the Inmarsat-4s, which deliver 99.9 per cent overall network availability. Ours is the only multi-band satellite network of its kind.

Upgrade path to higher bandwidth
And while Global Xpress complements our existing L-band services, it can also provide an upgrade path to existing customers who have higher bandwidth needs, and affords them the opportunity to migrate over time to the new GX services.
Inmarsat Global Xpress is transforming today's piecemeal approach to high-speed broadband satellite communications by bringing reliable, end-to-end global connectivity fr om a single trusted supplier.
We also remain well-positioned to continue growing our core L-band franchise. With three generations of spacecraft in operation, we continue to invest for the future here too.

New satellites to extend our L-band network
We intend to maintain our L-band network, and will purchase new satellites for this network on a rolling procurement basis, which means they'll be replaced over time rather than in a concentrated investment period.
This additional capacity brought by Global Xpress will also free us up to enhance our existing L-band portfolio – including BGAN, FleetBroadband and SwiftBroadband, and our global handheld satellite phone range, IsatPhone.
We see a future wh ere mobile satellite services are delivered through a combination of L-band and Ka-band satellites, harnessing the strengths of each to offer an unrivalled portfolio of solutions based on speed, price and portability.

In-flight passenger WiFi via S-band
The European Aviation Network (EAN), a revolutionary new hybrid satellite and air-to-ground network developed by Inmarsat in partnership with Deutsche Telekom,  promises aviation customers a high quality broadband service when flying over Europe.
With European air traffic forecast to double over the next decade, the EAN is designed to grow capacity to match accelerating demand. Initially combining Inmarsat's multi-beam S-band satellite with approximately 300 Deutsche Telekom ground towers, it's easily and cost-effectively scalable.
Passengers flying over Europe will be able to use their personal devices for internet browsing, video streaming, gaming and other online services, with unmatched high capacity, low-latency performance. EAN's robust and ultra-compact technology makes it uniquely qualified for the European airspace, wh ere aircraft size, flight density and frequent aircraft manoeuvring are challenging to broadband satellite-only systems.
It has been made possible by the European Commission's S-band Application Programme. This regulatory framework provides an ideal platform to roll-out the network across the continent.
As well as delivering value-added in-flight connectivity services to EU businesses and consumers, the aviation network is expected to foster high-value R&D, encourage product and service innovation, and bring new jobs and economic growth.
The cost of the satellite programme, estimated at US$200-250 million, will be shared with Hellas-Sat, which will gain exclusive rights to a companion Ku-band payload deployed on the satellite.

Parallel Ariane 5 mission preparations are underway for Arianespace's next dual payload heavy-lift launches

The build-up process for Flight VA238's Ariane 5 at the Spaceport began with erection of the core cryogenic stage and its positioning over the launch table inside the Launcher Integration Building (photos left and center), followed by the first of two solid booster rollouts for mating with the core stage (photo at right).

The Spaceport's ability to support Arianespace's launch cadence by enabling multiple missions to be readied in parallel is demonstrated once again with the two Ariane 5s currently undergoing processing in French Guiana.   
                            
Inside the Spaceport's Launcher Integration Building, the Ariane 5 for Flight VA238 is taking shape for a June 28 liftoff with a dual-satellite payload: the Hellas-Sat 3/Inmarsat S multi-mission relay satellite for Inmarsat and Hellas-Sat; and the Indian Space Research Organisation's GSAT-17 communications spacecraft.
This heavy-lift vehicle's build-up process began with the positioning of its core cryogenic stage over one of two mobile launch tables for Ariane 5. It cleared the way for the transfer of two large solid propellant boosters fr om their remote preparation zone to the Launcher Integration Building, where they will be mated to the Ariane 5's core stage.

 
Ariane 5's build-up performed by Airbus Safran Launchers
The basic build-up will then be completed with integration of Ariane 5's cryogenic upper stage and vehicle equipment bay, followed by checkout and functional tests.
 

The GSAT-17 satellite for Arianespace Flight VA238 undergoes pre-launch processing in the Spaceport's S5 payload preparation facility.
 
Performing this entire phase of launcher integration activity is Arianespace's parent company and Ariane 5 prime contractor: Airbus Safran Launchers.
Flight VA238's launcher will then be ready for transfer to the Spaceport's Final Assembly Building, wh ere it will receive the Hellas-Sat 3/Inmarsat S and GSAT-17 satellite passengers.
The Final Assembly Building currently is occupied by the Ariane 5 for Arianespace Flight VA237, which is set for a June 1 liftoff with the ViaSat-2 and Eutelsat E172B telecommunications satellites. This Ariane 5 is installed on the second mobile launch table used by Arianespace's heavy-lift vehicles, and awaits its dual-passenger payload integration.
Arianespace is targeting a total of 12 missions in 2017 utilizing its family of the heavy-lift Ariane 5, medium-lift Soyuz and light-lift Vega. So far in 2017, the launch services company has performed five flights from the Spaceport: two each with Ariane 5 and Soyuz, along with one Vega mission.
