Arianespace gives a "lift" to Intelsat 17 and HYLAS 1[/size]

November 26, 2010 – Ariane Flight 198

The fifth Arianespace mission of 2010 orbited two telecommunications payloads today: one for an emerging new player in the broadband marketplace; and the other for a long-time customer that is the world's leading provider of fixed satellite services.


This aerial photo details Ariane 5's initial climb-out from the ELA 3 launch zone at Europe's Spaceport, which is located adjacent to the Atlantic Ocean coastline in French Guiana.

Lifting off this afternoon from the Spaceport's ELA 3 launch zone in French Guiana, the heavy-lift Ariane 5 deployed its Intelsat 17 and HYLAS 1 passengers during a daytime mission lasting 49 minutes.  It was the 54th mission for the workhorse Arianespace vehicle and the 198th flight of an Ariane family launcher.

"Less than one month after our most recent Ariane 5 liftoff, we are together once again to celebrate the performance, reliability and availability of our launcher – which this evening marked its 40th consecutive success," said Arianespace Chairman & CEO Jean-Yves Le Gall in comments from the Spaceport's mission control room.  "This success also reinforces Ariane 5's position as a global reference, because since the start of 2010, it already has enabled us to orbit 10 large telecommunications satellites out of the 17 total launched worldwide."

Ariane 5 continued its track record of on-target payload deliveries, with the following provisional orbital parameters at the injection of its cryogenic upper stage:
- Perigee: 249.3 km. for a target of 249.3 km.
- Apogee: 35,950 km. for a target of 35,943 km.
- Inclination:  1.98 deg. for a target of 2.00 deg.

Intelsat 17 was released first during today's mission.  This 5,500-kg. spacecraft was built by Space Systems/Loral using its LS 1300 Omega satellite bus, and will deliver a wide range of communications services for Europe, Africa, the Middle East and India.  The satellite will be positioned at an orbital slot of 66 deg. East, operating with 25 Ku-band and 24 C-band transponders.

Le Gall noted Arianespace's long relationship with Intelsat, which spans almost three decades.  "It was a few kilometers from here that an Ariane 1 launcher – operating from the ELA 1 launch site – orbited the Intelsat 5 satellite, which also was built by Space Systems/Loral," Le Gall stated.  "Nearly 30 years later, we are marking the 51st satellite launched by Arianespace for Intelsat, which – over the years – has become one of our most important customers.  This also is the 29th time that a Space/Systems Loral-built spacecraft has been placed in geostationary transfer orbit with the services of Arianespace."


Ariane 5 ascends from the Spaceport during today's daytime launch, powered by its two solid propellant boosters and core cryogenic stage.

HYLAS 1 is the first satellite lofted by Arianespace for Avanti Communications.  Designed and built by EADS Astrium in partnership with the Indian Space Research Organisation, HYLAS 1 is to bring high-speed broadband services to remote rural areas across Europe – using the flexibility of its payload to change the bandwidth of its 8 Ka-band beams from an orbital position of 33.5 deg. West, maximizing the satellite's efficiency. This is complemented by a Ku-band broadcast capability.

"I would like to congratulate Avanti Communications for this superb entry into the world of space-based telecommunications operators," Le Gall said.  "The decision to place its confidence in Arianespace for the launch of this satellite becomes particularly pertinent this evening, as HYLAS 1 was launched with success before the end of 2010 – which is exactly as desired by our customer."

Le Gall noted that Arianespace is continuing its commercial success, as its order book backlog of satellites to be launched counts 29 satellites and six Automated Transfer Vehicles to be orbited – representing 22 Ariane 5 missions, along with 17 for Soyuz.

"Since the start of this year, we have signed 10 contracts for the launch of geostationary orbit satellites, along with six contracts for payloads to be launched by Soyuz," he added.  "I want to honor all who have contributed to this remarkable success."

Arianespace is maintaining its sustained mission pace, with the final launch of 2010 planned for December 21 with the Hispasat 1E and KOREASAT 6 satellites.

Hylas-1 Reaches Operating Orbit in Good Health[/size]
By Peter B. de Selding

    PARIS — The Hylas-1 broadband telecommunications satellite launched Nov. 26 has reached its final geostationary operating position and is in good health, the Indian Space Research Organisation (ISRO) announced Nov. 30.

    The satellite was built by a joint venture between ISRO's Antrix commercial arm and Astrium Satellites of Europe, with the Indian side providing the satellite bus and Astrium handling the electronics payload. The payload includes a new subsystem, built with European Space Agency funding, to permit Hylas-1 owner Avanti Communications of London to adjust power and broadcast frequencies among different regions in response to demand for broadband service.

    Hylas-1 can provide 3 kilowatts of power to its two Ku-band channels and eight Ka-band channels. It will be operated at 33.5 degrees east. ISRO, which is handling the satellite's early orbit operations, said Hylas-1's orbit has been nearly circularized to geostationary position about 36,000 kilometers over the equator following three sequences during which its liquid-fueled apogee motor was fired.

    The satellite is in continuous radio contact with ISRO's Hassan master satellite control facility in southwest India, and has deployed one of its communications antennas, ISRO said.

    Avanti has contracted with Orbital Sciences Corp. of Dulles, Va., to build a larger Hylas-2 satellite to be ready for launch in 2012. Hylas-2, using the Orbital Star 2.7 platform, will provide 5 kilowatts of power to a payload of 24 Ka-band user beams and four gateway beams.

    Like Hylas-1, Hylas-2 will be launched by Europe's Arianespace consortium of Evry, France.

Orbit testing is complete and new capacity contract comes in...

Avanti Communications Group plc (LSE: AIM) has formally completed in orbit testing of the HYLAS 1 satellite. The testing process confirmed that HYLAS 1 is working in conformance with specification and, in some areas, delivering higher performance than originally specified. The satellite lifetime is expected to be at least six months greater than planned and the available power is several percentage points better than specification. This will translate into improved service quality, flexibility and usable capacity. The provision of services on HYLAS 1 will now commence. The first live customer service in the UK will be installed next week. Avanti has a test customer base of 5,000 end users whose service is delivered with leased Ku-band capacity. The migration of these customers to HYLAS 1 will begin on April 4th. Avanti has more than 60 Virtual Network Operator customers in 16 countries in Europe who have bought capacity. Many of them are also migrating existing end user customers from leased Ku band capacity on other satellites and this migration also begins on April 4th.

Avanti is also pleased to announce that yesterday it signed a seven year contract with a new Virtual Network Operator Customer for the sale of 80 Mb of capacity (with volume beginning at a lower level in year one and rising to 80Mb to match the customer's expansion in end users). The contract, which commands pricing which exceeds market expectations, is worth 7.1m euros over the seven year term. The customer has approximately 3,000 satellite broadband end user installations in Europe which currently use Ku-band capacity on a competitors' satellite. The customer will migrate that existing client base to HYLAS 1 and then grow its business further with Avanti. For reasons of commercial sensitivity during this migration period, the customer is not named.

Европейский спутник Hylas-1 в ближайшее время начнет работать[/size]
(17:23) 24.03.2011

Европейское космическое агентство сегодня сообщило о готовности нового спутника Hylas-1 к работе. Данный аппарат должен будет предоставлять европейским потребителям услуги широкополосного доступа к интернету. Спутник был запущен в космос в ноябре прошлого года и с тех пор технические специалисты в центре координации полетов ЕКА в Бельгии проводили технические работы по тестированию всех видов оборудования на спутнике.

Сейчас в ЕКА говорят, что все основные системы спутника готовы к началу работы.

Спутник Hylas-1 является первым европейским аппаратом, предназначенным исключительно для получения широкополосного доступа в сеть, а также для смежных коммуникационных решений, таких как VoIP. В Европейском космическом агентстве называют спутник Hylas "высокоадаптируемым аппаратом", с ориентацией на домашних потребителей и малый бизнес. В ЕКА говорят, что новый спутник по-своему уникален, так как предоставляет услуги связи не бизнесу и крупным правительственным заказчикам, а простым жителям ЕС.

По словам специалистов, оборудование, установленное на спутнике, является многофункциональным, хотя и ориентированным на передачу данных. Ожидается, что на первом этапе интернет-мощности аппарата не будут загружены на 100%, поэтому они будут задействованы для других нужд, в частности для передачи видеосигнала в HD-качестве.

Hylas оснащен рядом транспортеров Ku- и Ka-диапазонов. Ka-диапазон обеспечит покрытие избранных частей Европы, где наиболее велики коммерческие возможности по использованию спутниковых мощностей. В ЕКА говорят, что Ка-транспондеры могут обеспечить европейских потребителей "эффективными коммуникациями точка-точка, обладающими низкой себестоимостью". В компании Avanti, разрабатывавшей аппарат, сообщают, что уже на первом этапе работы Hylas стоимость услуг будет приемлемой для европейского частного сектора.

Работа над аппаратом стартовала в декабре 2005 года.
