Ariane 5 | August 6, 2019
Arianespace's Ariane 5 orbits key telecommunications payloads on its third launch of 2019


The Ariane 5 for Flight VA249 departs the Spaceport's ELA-3 launch zone with its Intelsat 39 and EDRS-C satellite passengers.

Arianespace marked another success for global telecommunications with launch of the Intelsat 39 and EDRS-C satellites, which were deployed to geostationary transfer orbit on its latest flight using a workhorse Ariane 5.

This mission – designated Flight VA249 in Arianespace's numbering system – was performed from the Spaceport's ELA-3 launch zone in French Guiana, with Ariane 5 deploying its passengers during a mission lasting 33 minutes from liftoff to final separation.

A daytime liftoff for the ArianeGroup-supplied Ariane 5

The Ariane 5 lifted off as scheduled at 4:30 p.m. (local time in French Guiana), providing an excellent view of the launcher's initial trajectory during its daytime launch – including separation of the two solid propellant boosters at just over two minutes into the flight.

Ariane 5 – which is delivered to Arianespace by ArianeGroup as production prime contractor – delivered an estimated total lift performance of 10,260 kg. on today's mission, factoring in Intelsat 39 and EDRS-C, plus hardware for the dual-payload deployment system.

"With this third Ariane 5 of the year orbiting our fifth and sixth Geosynchronous Equatorial Orbit satellites, our heavy-weight launcher reasserts its leading position on the GEO market," said Luce Fabreguettes, Arianespace's Executive Vice President – Missions, Operations & Purchasing. "Indeed, VA249 marks the 377th and 378th GEO satellites orbited by Arianespace! Let me congratulate all our partners who played their part in this success."

Another success for Intelsat

Deployed first in the flight sequence, Intelsat 39 is designed with both wide and high-powered steerable spot beams to meet the needs of broadband networking, video and government customers across Africa, Asia, Europe, the Middle East and Indian Ocean region. The steerable spot beams provide flexibility within the payload and enable customers to rapidly and efficiently respond to shifts in geographic or application requirements.

Built by Maxar Technologies, the satellite features C-and Ku-band capabilities to provide additional scale for Intelsat's Flex managed service and enhance mobile connectivity for aero, maritime and government users operating across these regions.

Intelsat 39 is the 61st Intelsat spacecraft launched on an Arianespace mission, continuing a partnership that extends back to 1983. The satellite will replace Intelsat 902 – lofted by Arianespace in 2011 – at an orbital position of 62 deg. East.

Expanding the SpaceDataHighway

EDRS-C – released next in the flight sequence, four minutes after Intelsat 39 – is the second node of the SpaceDataHighway, which is the world's first "optical fiber" network in the sky based on cutting-edge laser technology. Permanently fixed over a network of ground stations, the SpaceDataHighway will help improve environmental and security monitoring, disaster response and crisis management.

Based on a platform supplied by OHB System, EDRS-C will be able to connect low-orbiting observation satellites via laser at a distance up to 45,000 km., as well as unmanned aerial vehicles or mission aircraft – operating from an orbital position at 31 deg. East.

The SpaceDataHighway is a public–private partnership between Airbus and the European Space Agency (ESA), with the laser terminals developed by Tesat-Spacecom and Germany's DLR Aerospace Center. Airbus owns, operates and provides services for the SpaceDataHighway. EDRS-C was the 132nd satellite launched by Arianespace at the service of Airbus.

EDRS-C also carried a hosted payload – HYLAS 3 – which was provided by Avanti Communications under a contract with ESA as a customer-furnished item to OHB. It is this operator's fourth satellite to be launched by Arianespace.

Ariane 5 by the numbers

As Arianespace's third Ariane 5 launch in 2019, Flight VA249 follows the company's other heavy-lift missions performed this year on February 5 (carrying Saudi Geostationary Satellite 1/Hellas Sat 4 and GSAT-31) and June 20 (T-16 and EUTELSAT 7C).

Flight VA249 also marked the 249th launch of an Ariane-series vehicle overall, and the 105th using Ariane 5.

Ariane 5 | August 6, 2019
Arianespace successfully orbits two communications satellites: INTELSAT 39 for INTELSAT; and EDRS-C for Airbus



Arianespace has successfully orbited two geostationary telecommunications satellites: Intelsat 39 for the international operator Intelsat, and EDRS-C for Airbus, as part of a public-private partnership with the European Space Agency (ESA).

The launch took place on August 6, 2019 at 4:30 p.m. (local time) from the Guiana Space Center (CSG), Europe's Spaceport in French Guiana (South America).

With this third successful Ariane 5 mission in 2019, Arianespace continues to prove its ability to meet the requirements of today's most innovative players in both the commercial and institutional markets.

After the mission's completion, Arianespace Chief Executive Officer Stéphane Israël said: "With this launch for two of our long-standing customers, Intelsat and Airbus – as well as in the framework of a partnership with ESA and Avanti – we proudly continue to show our ability to deploy ever more innovative satellites for commercial and institutional requirements."

Arianespace orbits Intelsat 39 for Intelsat, a partner since 1983

Intelsat 39 is the 61st satellite launched by Arianespace for Intelsat, starting with its first mission for this operator in 1983. It will replace the Intelsat 902 spacecraft, launched by Arianespace in 2001.

The Intelsat 39 telecommunications satellite offers high-power, steerable, wide spotbeams to meet the needs of broadband network, video and government customers across Africa, Asia, Europe, the Middle East and the Indian Ocean region. Steerable spotbeams ensure payload flexibility, enabling customers to quickly and efficiently respond to changing geographic or application requirements.

The satellite features both C- and Ku-band capabilities to provide additional scale for Intelsat's Flex managed services and enhance mobile flexibility for aeronautical, maritime and government users in these regions.

Intelsat 39 was built by Maxar in Palo Alto, California. It is the 57th satellite launched by Arianespace using a Maxar platform.

Arianespace: a catalyst for innovative satellite solutions serving Europe

The EDRS-C satellite is the second node in the SpaceDataHighway network. Based on state-of-the-art laser technology, EDRS, the SpaceDataHighway is the first fiber-optic network in space. Supported by a public-private partnership between Airbus and ESA, it will help improve environmental monitoring and security services, disaster response and crisis management. The European commission will be a key customer of the EDRS system at the benefit of the Copernicus program. Once again, Arianespace has fulfilled its primary mission of offering independent access to space for Europe's flagship programs.

The SpaceDataHighway is the most sophisticated laser communications network ever designed. From a position in geostationary orbit, it relays data collected by observation satellites to Earth in near real time, thus tripling the volume of data, images and videos transmitted by these satellites and also being capable of reprogramming their mission plan at any given moment in just a few minutes.

The laser terminals were designed by Tesat-Spacecom and Germany's DLR aerospace research center. Airbus owns, operates and services the SpaceDataHighway. The EDRS-C satellite platform is supplied by OHB System AG, while the HYLAS 3 hosted payload was provided by the operator Avanti Communications under a contract with ESA.

EDRS-C is the 132nd satellite launched by Arianespace for Airbus, as well as the 26th satellite using an OHB platform and the fourth Avanti payload to be launched by Arianespace.

Ракета Ariane 5 успешно вывела на промежуточные орбиты два телекоммуникационных спутника

Речь идет об аппаратах Intelsat 39 и EDRS-C

ПАРИЖ, 6 августа. /ТАСС/. Европейская ракета-носитель тяжелого класса Ariane 5 успешно разместила на промежуточных орбитах в ночь на среду два спутника связи. Об этом сообщил в трансляции через интернет Гвианский космический центр, с космодрома которого стартовала ракета.

На рабочие геостационарные орбиты Земли выводятся два спутника связи - Intelsat 39 и EDRS-C. Intelsat 39 запускается для крупнейшего международного оператора связи Intelsat. EDRS-C является частью совместного проекта Европейского космического агентства и корпорации Airbus по космической лазерной связи. После успешного отделения спутников от головной части ракеты управление ими передано компаниям-владельцам.

"Новая миссия Ariane 5 блистательно завершена", - подчеркнула, выступая в центре управления полетом исполнительный вице-президент корпорации Arianespace Люс Фабрегетт. Она сообщила также, что корпорация Arianespace заключила с Airbus контракты в целом на вывод на орбиты 21 аппарата.

Нынешний пуск ракеты Ariane 5 стал третьим в этом году для данного носителя и седьмым по счету, проведенным "Арианспейс" из Гвианского космического центра.

Европейская ракета-носитель Ariane 5 вывела на орбиту два спутника связи

Москва. 6 августа. INTERFAX.RU - Тяжелая ракета-носитель Ariane 5 Европейского космического агентства (ЕSА) во вторник успешно вывела на орбиту два телекоммуникационных спутника, сообщила ее французская компания-разработчик Arianespace.

Запуск был осуществлен в 22:30 мск с космодрома "Куру" во Французской Гвиане. Это уже третий пуск Ariane 5 в текущем году.

По сообщению компании, через 33 минуты после старта Ariane 5 вывела на орбиту европейские спутники Intelsat 39 оператора связи Intelsat и EDRS-C ЕКА и компании Airbus. Стартовая масса выведенного ракетой на орбиту груза составила 6,6 тонн.

Спутник Intelsat 39, оснащенный передатчиками C- и Ku- диапазонов, предназначен для обеспечения широкополосного доступа в интернет и спутникового телевещания в Африке, Европе, на Ближнем Востоке и в Азии. Он будет размещен на 62-м градусе восточной долготы. Аппарат заменит исчерпавший свой ресурс Intelsat 902, выведенный на орбиту Земли в 2001 году.

Что касается спутника EDRS-C, то он станет вторым составным элементом первой системы оптической космической связи в Европе SpaceDataHighway. Ее разработчиком выступает аэрокосмическая компания Airbus Defence and Space. Система предназначена для оптической передачи данных с использованием лазерного терминала. Система EDRS может передавать примерно около 50 терабайт данных ежедневно со скоростью до 1,8 гигабит в секунду.

Спойлер

Старт ракеты Ariane 5 с европейскими спутниками первоначально планировался 24 июля. Он был отложен в связи с неудачным пуском легкой французской ракеты-носителя Vega с разведывательным спутником Falcon Eye 1 (оптико-электронным спутником дистанционного зондирования Земли) Объединенных Арабских Эмиратов. Примерно через две минуты после старта ракета Vega из-за сбоя в работе двигателей второй ступени отклонилась от заданной траектории и упала в Атлантический океан.

Bremen/ Kourou, August 06, 2019. The telecommunications satellite EDRS-C, which is the second node of the SpaceDataHighway system (also known as European Data Relay System, EDRS), lifted off from the European Space Center in Kourou, French Guiana at 21:30 CEST on August 06, 2019. The 3.2 ton satellite was engineered and manufactured by space systems specialist OHB System AG, a subsidiary of listed company OHB SE. It separated from the Ariane 5 launch vehicle on schedule after an ascent lasting about 30 minutes. A few minutes later, the EDRS-C satellite transmitted its first "signs of life" from space.

"I would like to thank Airbus and ESA for the trust they have placed in OHB and all those involved at OHB as well as our many subcontractors for their valuable contributions. I am eagerly awaiting the day on which our second SmallGEO satellite goes into operation and supplements the SpaceDataHighway," said Guy Perez, company CTO and member of the Management Board of OHB System AG responsible for telecommunications.

Europe's laser-based data relay system is being implemented as a public-private partnership between the European Space Agency (ESA) and Airbus. A constellation of geostationary satellites will be linked to a network of ground stations and, using innovative laser communication technology, will receive data from Earth observation satellites from lower orbits and relay it to ground stations in Europe, in near real-time and at a rate of 1.8 Gbit/s. Specifically designed for optical communications, the EDRS-C satellite developed, manufactured and tested by OHB on the basis of the SmallGEO platform forms the second node of the system. It also incorporates the HYLAS 3 Ka-band payload delivered to OHB System AG by ESA on behalf of Avanti Communications as a customer-furnished item.

OHB's contractual partners include international suppliers and service providers as well as other OHB Group companies. The ESA EDRS programme is being supported by the German Space Administration at DLR (German Aerospace Center), which has received funding from the German Federal Ministry for Economic Affairs and Energy and the Bavaria state government for the development of the system.

EDRS-C SpaceDataHighway

 European Space Agency, ESA

Опубликовано: 4 авг. 2019 г.

Kourou, French Guiana, at Europe's spaceport the EDRS-C satellite is being prepared for launch. Soon this second node of the European Data Relay system will join the EDRS-A node already in orbit, as the first dedicated EDRS satellite. EDRS has been designed to enable fast and reliable optical data transfer from low earth orbiting satellites to the ground. To achieve this the EDRS system uses state-of-the art laser link communication terminals and in combination with the longer data transmission offered EDRS, much more data can be transferred to the ground in Quasi Real Time, thus creating a real SpaceDataHighway
