Ariane 5 | June 1, 2017

Arianespace marks its 2017 mid-year launch milestone with a record-setting Ariane 5 mission at the service of ViaSat and Eutelsat


The Ariane 5 for Flight VA237 is shown at the Spaceport's ELA-3 launch zone, ready for liftoff with its ViaSat-2 and EUTELSAT 172B satellite passengers.

On its sixth successful launch during the first half of 2017, Arianespace's Ariane 5 set a new heavy-lift record tonight in delivering the ViaSat-2 and EUTELSAT 172B telecommunications satellites to geostationary transfer orbit.

This mission underscored the increased payload lift capability provided for the Ariane 5 ECA version during the heavy-lift workhorse's operational career, setting another record for the total mass carried into geostationary transfer orbit. The delivery involved a total payload of 10,865 kg. – of which 9,969 kg. was the net liftoff mass for the two satellites, with the other mass including integration hardware for Ariane 5's dual-payload deployment system.

"With this new mission, Arianespace once again demonstrates the availability and versatility of its launch vehicle family for customers," explained Arianespace CEO Stéphane Israël. "For the third time this year and the 79th time in a row, Ariane 5 performed flawlessly. Well done! Congratulations to all!"

 

Providing more lift capability to the workhorse Ariane 5 ECA

Speaking from the Spaceport, Israël noted the Ariane 5 ECA's payload lift capability has been given an overall performance gain of more than 1.5 metric tons since the beginning of this launcher program, and will be further increased in steps through 2019, boosting it by another 250 kg. – enabling Arianespace to meet evolving customer requirements. This enhancement involves support of the European Space Agency, the French CNES space agency and Ariane 5 industrial prime contractor Airbus Safran Launchers, he added.

Tonight's mission – designated Flight VA237 in Arianespace's launcher family numbering system – keeps the company on track for the 12 flights targeted in 2017. It follows the five previous launches this year – two by Ariane 5, two by Soyuz and one by Vega – and clears the way for Arianespace's next Ariane 5 mission, scheduled for June 28, along with three more Ariane 5 liftoffs and two Vega launches planned during the second half of 2017.

The first passenger released during Flight VA237 was ViaSat-2, which is to be operated from an orbital position of 70 deg. West by ViaSat – a global broadband services and technology company headquartered in Carlsbad, California, USA.

 

ViaSat-2: enhancing connectivity over a wide coverage area

With the goal of improving global connectivity, ViaSat-2 is to bring considerable improvements in terms of speed, lower costs and extended broadband across its coverage zone – which includes North and Central America, plus the Caribbean, northern South America, and aeronautical and maritime routes in the Atlantic Ocean between North America and Europe.

ViaSat-2 was the second satellite to be launched by Arianespace for VisSat. Based on Boeing's 702HP platform, it also was the 54th Boeing-built satellite orbited by the company.

 

An electric satellite "first" for Ariane 5

Completing tonight's Flight VA237 was the deployment of EUTELSAT 172B – the 32nd satellite launched by Arianespace for Paris-based Eutelsat, a leading satellite operator in Europe, the Middle East and Africa.

EUTELSAT 172B will increase Eutelsat's capacity for fast-growing applications, such as in-flight and at-sea connectivity, mobile network interconnections, video and government services. Built by Airbus, it will be positioned at 172 deg. East – a strategic orbital position for coverage of Asia-Pacific, on land and at sea, from Alaska to Australia.

As the 118th Airbus-produced satellite orbited by Arianespace, this spacecraft uses the Eurostar E3000 EOR (Electric Orbit Raising) platform – becoming the first all-electric telecommunications satellite orbited by an Ariane 5.

Arianespace at the service of ViaSat Inc.

ViaSat-2 is the second ViaSat Inc. satellite to be launched by Arianespace, after WildBlue-1 in 2006.

ViaSat, a global broadband services and technology company, aims to change the general perception of satellite internet, globally. The company has set out to advance global connectivity and solve one of the hardest communications problems: making the internet accessible and affordable to all.

The ViaSat-2 satellite system will bring considerable improvements in terms of speed, lower costs and extended broadband coverage. Its coverage zone includes North and Central America, plus the Caribbean, northern South America, and aeronautical and maritime routes in the Atlantic Ocean between North America and Europe.

ViaSat has also chosen Arianespace to launch a ViaSat-3 class satellite, further extending the partnership between the two companies.

ViaSat-2 was built by Boeing in El Segundo, California, using the 702HP platform.  [/li] 54th Boeing satellite launched by Arianespace since orbiting Aussat K3 in 1987. 4th satellite based on the 702HP platform to be launched by Arianespace. 3 other Boeing satellites in the Arianespace order book for future launches.

Arianespace launches first all-electric satellite for Eutelsat with Ariane 5

EUTELSAT 172B is the 32nd satellite launched by Arianespace for Eutelsat, starting with EUTELSAT-1 F1 in 1983.

Eutelsat is one of the world's leading telecom satellite operators, with a fleet of 39 satellites serving a broad range of customers.

Including today's mission, Arianespace has now orbited more than half of all Eutelsat satellites.

EUTELSAT 172B will increase the operator's capacity for fast-growing applications, such as in-flight and at-sea connectivity, mobile network interconnections, video and government services. It will be positioned at 172° East – a strategic orbital position providing exceptional coverage of Asia-Pacific, on land and at sea, from Alaska to Australia.

Two more Eutelsat satellites are in Arianespace's order book.

EUTELSAT 172B is the first all-electric telecommunications satellite to be built in Europe by Airbus, in Toulouse, France, and uses the new all-electric Eurostar E3000 EOR (Electric Orbit Raising) platform.

It is also the first all-electric satellite to be launched by Arianespace on an Ariane 5.

Airbus' development of all-electric Eurostar satellites was supported by ESA and European national space agencies, especially CNES in France, in the framework of the PIA program (Program for Investments in the Future). [/li] EUTELSAT 172B is the 118th Airbus satellite launched by Arianespace. The Arianespace order book includes 15 Airbus satellites to be launched.

Arianespace confirms its advantages: reliability, performance, availability, flexibility

79th success in a row for Ariane 5, and a new performance record for the Ariane 5 ECA version

The payload for Flight VA237 set a new record for the mass carried into geostationary transfer orbit, totaling 10,865 kg. (9,969 kg. net for the satellites). With this performance, Ariane 5 beats its previous record of 10,737 kg. (9,856 kg. for the satellites), set on August 24, 2016 during Flight VA232. This launch brings the total performance gain achieved since the beginning of Ariane 5 ECA operations to more than 1.5 metric tons. This performance will continue to gradually increase during the coming years.

 

A sustained launch rate, thanks to the availability of Arianespace's launcher family

With six launches, all successful, between January 27 and June 1 (three by Ariane 5, two by Soyuz and one by Vega), Arianespace maintains a sustained pace of operations. To date this year, Arianespace has already orbited eight geostationary satellites, totaling 34.57 metric tons, and one Earth observation satellite.

The three successful launches in less than a month – two by Ariane 5 (May 4 and June 1) and one by Soyuz (May 18 )  –  clearly show the operational maturity of Arianespace's family of launchers. The next Ariane 5 launch, planned for June 28, will bring the total number of launches in the first half of 2017 to seven. Three more Ariane 5 missions and two with Vega are planned during the second half of the year.

Arianespace at the service of in-flight connectivity

The in-flight connectivity market, boosted by strong development momentum, is expected to grow by 300% in the next 10 years, with the number of Internet-enabled aircraft increasing from 5,300 in 2015 to more than 26,500 in 2025. Arianespace clearly supports these new space-based applications designed to improve people's lives, with six geostationary satellites dedicated to in-flight connectivity in its order book for future launches, plus the OneWeb low-Earth orbit constellation.

Shortly after the announcement of the orbital injection of the two satellites on today's Flight VA237, Arianespace Chief Executive Officer Stéphane Israël said: "With this third successful Ariane 5 launch of the year, and the 79th consecutive success in a row, Arianespace proudly delivers its service excellence to our American and European customers in support of global connectivity. The new all-time payload weight record set by this launch, which also was the first orbiting of an all-electric satellite by our heavy launcher, confirms the power and flexibility of Ariane 5.

"We are very honored by the confidence shown by ViaSat Inc., which has chosen Arianespace for the second time, as well as that of the European operator Eutelsat, for whom we have launched 32 satellites since 1983. Our congratulations to Boeing, which built ViaSat-2, and to Airbus, which built EUTELSAT 172B – the first satellite to use Europe's all-electric Eurostar E3000 EOR platform.

"I would also like to thank all of our partners in this 93rd Ariane 5 launch: our majority shareholder Airbus Safran Launchers and the entire European launcher industry, for the exceptional reliability and availability of Ariane 5; the European Space Agency, which provides essential support for the Ariane program; the French CNES space agency and the Guiana Space Center; and our ground segment companies and all staff at the space center, who continue to work alongside us as we go from success to success. And of course, I would like to congratulate everybody at Arianespace for this successful sixth launch of the year!"

ViaSat-2 was built by Boeing in El Segundo, California, using the 702HP platform. Positioned at 70° West, it will provide about 300 Gbps of throughput in Ka-band for North and Central America and the Caribbean, northern South America, and the aeronautical and maritime routes in the Atlantic Ocean between North America and Europe. It weighed 6,418 kg. at liftoff and offers a design life exceeding 14 years. EUTELSAT 172B was built by Airbus in Toulouse, France, using the new all-electric Eurostar E3000 EOR platform. Positioned at 172° East, EUTELSAT 172B will provide fixed and mobile services, as well as in-flight connectivity for the Asia-Pacific region. It weighed 3,551 kg. at liftoff and offers a design life exceeding 15 years.

Airbus: First high power all-electric satellite, EUTELSAT 172B, launched by Ariane 5

June 2, 2017 - Press release

All-electric propulsion for orbit-raising and on-station manoeuvers for the first time on a high power satellite inaugurates significant mass savings on this class of mission
Innovative payload technology will dynamically distribute power between spot beams to provide internet connectivity to aircraft over the Pacific
 
Kourou, 02/06/2017 –EUTELSAT 172B, the first high power all-electric telecommunications satellite worldwide built by Airbus for Eutelsat, one of the world's leading satellite operators, has been successfully launched from Kourou, French Guiana by Ariane 5. The satellite will provide enhanced telecommunications, in-flight broadband and broadcast services for the Asia-Pacific region.

"We are the first company to demonstrate full electric propulsion for satellites of this size and capacity," said Nicolas Chamussy, Head of Space Systems at Airbus. "With this spacecraft we are clearly setting a new benchmark - enabling powerful and complex satellites to be launched in the most cost efficient manner."

EUTELSAT 172B combines electric power of 13 kW with a launch mass of around 3,500 kg only, thanks to the latest EOR (Electric Orbit Raising) version of Airbus' highly reliable Eurostar E3000 platform.

Спойлер

Full electric propulsion for initial orbit raising and all on-station manoeuvres, with Xenon gas ejected at high speed using only electric power supplied by solar cells, relieves operators of the need to include tons of chemical propellant, leading to up to 40% mass savings on the satellite.

Customers can therefore either achieve a significant saving on launch costs, or a substantial increase of the payload power for a given mass. Furthermore the Hall Effect Technology used by Airbus makes transfer to the operational orbit significantly faster than other electric propulsion technologies.

Innovation solutions include two deployable robotic arms to orientate the satellite's electric propulsion thrusters to control thrust direction and attitude during different phases of the mission. In addition, WALIS (Wide Angle Localisation Integrated System) is a proprietary network of ground stations developed by Airbus around the world, to enable Airbus engineers to control orbit raising operations until the satellite reaches geostationary orbit.

The development of Airbus' Eurostar all electric satellites has been supported by ESA and space agencies of European countries, in particular in France by CNES in the framework of the PIA programme (Plan d'Investissements d'Avenir) and in the UK by the UK Space Agency.



EUTELSAT 172B hosts three distinct payloads that will strengthen Eutelsat's capabilities across Asia-Pacific markets: a C-band payload, a regular Ku-band payload and a high throughput Ku-band payload designed for in-flight connectivity along Pacific air corridors.in that regard, the satellite features an innovative multi-port amplifier (MPA) on the payload to distribute dynamically the satellite's power between its 11 spot beams to provide internet connectivity for aircraft flying across the Asia-Pacific region.

The flexibility of the MPA means that more power can be allocated to each spot beam as demand increases giving aircraft passengers a better service. The MPA technology was developed by Airbus as part of the European Space Agency's Advanced Research in Telecommunications Systems programme and supported by the UK Space Agency.

Additive layer manufacturing, or 3D printing, is further exploited for several elements on this satellite, including for a single printed bracket that is 35% lighter than and quicker to manufacture than the complex component it replaced.

Да вроде нет. "Полностью электрическая" у Боинга платформа 702SP (Small Power).
А Viasat-2 на платформе 702HP (High Power). У которой "электрические" (XIPS) только двигатели ориентации и коррекции, а апогейник - жидкостный, двухкомпонентный.

ViaSat-2 employs a hybrid propulsion system with traditional chemical propulsion for the initial climb toward Geostationary Orbit and electric propulsion for orbital fine-tuning and stationkeeping maneuvers. The satellite is equipped with a bipropellant Liquid Apogee Engine that is used for the initial climb to Geostationary Orbit. In addition, the satellite uses four axial 22-Newton Thrusters and four radial 10-Newton thrusters for smaller orbit adjustments, drifting in Geostationary Orbit and attitude maneuvers.

Approximately 29 minutes after liftoff, the ViaSat-2 mission was underway with the satellite separating from the launch vehicle. First signals from the satellite were acquired shortly thereafter through a ground station at Hassan, India. In the coming days, ViaSat-2 will start orbit raising with its chemical propulsion system, followed by solar array deployments, and will then switch over to its electric propulsion system to complete orbit raising over the coming months. ViaSat expects it will take several months for ViaSat-2 to reach its final orbital destination, located at 69.9° west longitude.

Mark Dankberg, ViaSat's chairman and CEO commented, "Today's successful launch is a momentous event in ViaSat's history. It represents the culmination of hard work, dedication and commitment to technical excellence from across the ViaSat team. We also want to recognize our launch team partners, Boeing and Arianespace, for their support and collaboration in helping us successfully launch ViaSat-2."

ViaSat-2 is a geostationary satellite that operates in Ka-band frequencies. It was designed to offer high-capacity connectivity and wide coverage, with the flexibility to move capacity to wh ere demand requires it. ViaSat-2 is expected to significantly improve speeds, reduce costs and expand the footprint of broadband services across North America, Central America, the Caribbean, a portion of northern South America, as well as the primary aeronautical and maritime routes across the Atlantic Ocean between North America and Europe.

Dankberg continued, "The innovations in our ViaSat-2 spacecraft and underlying network will enable us to be one step closer to connecting the world, and delivering new higher speed fixed and mobility services that will continue to compete with traditional broadband services."

"Arianespace is excited to have delivered for ViaSat!  We are proud to have launched one of the world's most advanced telecommunications satellites, ViaSat-2, safely to orbit. Great things are in store for our friends at ViaSat," said Stéphane Israël, CEO of Arianespace.

"We are honored that ViaSat has put their trust in Boeing to build and deliver their next-generation satellite, ViaSat-2, a high-power 702 satellite with advanced capabilities that will help ViaSat connect millions around the world through high-speed broadband service," said
Mark Spiwak, president, Boeing Satellite Systems International.

Boeing Satellite for ViaSat to Significantly Enhance Satellite Broadband Communications

The Boeing 702 ViaSat-2 satellite is one of the largest high-power commercial satellites built by Boeing


EL SEGUNDO, Calif., June 2, 2017 – Leveraging the recently launched Boeing [NYSE] 702 high-power satellite, ViaSat's second-generation satellite, ViaSat-2, will realize a seven-fold increase in broadband internet service coverage fr om its previous generation satellite and offer twice as much capacity on orbit.

ViaSat-2 will also offer flexibility to move satellite capacity to wh ere broadband demand exists and is the first satellite Boeing built for the company. Boeing is on contract to build two more satellites, under the ViaSat-3 program, both based on the 702 design and integrated with ViaSat payload technology.

"ViaSat-2 is a major technological achievement. It advances satellite system design and will provide the best economics, quality and service capabilities available in the industry," said Mark Dankberg, chairman and chief executive officer of ViaSat. "These advancements required a spacecraft partner, like Boeing, that could understand our vision for satellite broadband. We would like to thank Boeing for their hard work, expertise and contributions to the ViaSat-2 program. Our collaboration will enable ViaSat to bring internet to millions of users on the ground, in the air and at sea."

The satellite was launched, and sent its first signals from space, on June 1.

"We're glad to have continued to advance this flexible platform, relying on its flight-proven technology, while in great partnership with ViaSat to achieve their vision of connecting the world," said Mark Spiwak, president, Boeing Satellite Systems International."
