Enhancing telecommunications: Arianespace's Ariane 5 delivers T-16 and EUTELSAT 7C to geostationary transfer orbit



Arianespace launched two telecommunications satellites tonight on the latest Ariane 5 success, marking the company's 310th flight overall and underscoring its ability to deliver "any payload to any orbit at any time" from Europe's Spaceport in French Guiana.

Conducted from the ELA-3 launch pad, today's mission deployed an estimated payload lift performance of 10,594 kg. to geostationary transfer orbit. T-16 was released first in the sequence, separating from Ariane 5 27 minutes after liftoff, followed six minutes later by its EUTELSAT 7C co-passenger.

"For the second Ariane 5 launch of the year, our heavy-weight vehicle has once more performed perfectly," said Arianespace CEO Stéphane Israël, who provided his post-flight comments from the Spaceport's mission control center. "Congratulations to all!"

Another dual-payload delivery for Ariane 5
T-16 – produced in France by Airbus Defence and Space, based on the Eurostar 3000 LX Hybrid platform – will provide high-power broadcast services in Ku- and Ka-bands.

Being flexible, this hybrid-propulsion-powered broadcast satellite can be operated from five different orbital slots (from 99 deg. West to 119 deg. West) – with a coverage area that includes the continental United States, Alaska, Hawaii and Puerto Rico. Its liftoff mass was estimated at 6,350 kg.

EUTELSAT 7C, an all-electric-propulsion telecommunications satellite for operation by Eutelsat, was released from the Ariane 5 launcher's lower payload position. It was built by Maxar Technologies in the U.S. state of California using the company's 1300-140" All-Electric platform and weighed approximately 3,400 kg. at liftoff.

Once operational from its orbital position at 7 deg. East, EUTELSAT 7C will significantly increase capacity over Sub-Saharan Africa – making room for several hundred additional digital channels as this region's television market continues to grow at a rapid pace.

Continuing the 2019 launch cadence
Flight VA248 was Arianespace's fifth launch so far in 2019, and it follows one other Ariane 5 mission performed this year on February 5 – which successfully orbited the Saudi Geostationary Satellite 1/Hellas Sat 4 and GSAT-31 satellites.

Also conducted earlier in 2019 were Soyuz missions on February 27 (carrying OneWeb constellation satellites) and April 4 (O3b constellation satellites); plus Vega's March 21 flight with the Italian PRISMA Earth observation spacecraft.

The next launch on Arianespace's schedule is Vega Flight VV15, which will orbit a payload for the United Arab Emirates on July 5.

Arianespace chalks up another success with Ariane 5, launches T-16 and EUTELSAT 7C



Arianespace confirms its status as a trusted partner to world-class operators of communications satellites with the launch of T-16 and EUTELSAT 7C.

The company's fifth launch of 2019 took place on Thursday, June 20 at 6:43 pm (local time) from the Guiana Space Center (CSG), Europe's Spaceport in Kourou, French Guiana.

With this latest success, the second with an Ariane 5 launch vehicle in 2019, Arianespace consolidates its leadership in the market for commercial launches into geostationary orbit. Today's launch was the 104th overall for an Ariane 5 and the 310th launch by the Arianespace family.

Following the launch, Stéphane Israël, Chief Executive Officer of Arianespace, said: "I would like to thank our two loyal customers for entrusting us with the launch of their T-16 and EUTELSAT 7C satellites. This second Ariane 5 launch of the year reaffirms the reliability of our heavy-lift launcher and its leadership in the geostationary market. We are very proud to count 24 GEO satellites in our order book. Some of them will be launched by Ariane 6, the new-generation launch vehicles scheduled to make its first flight in 2020."

Arianespace supports two world leaders in satellite communications
EUTELSAT 7C is the 33rd satellite to be launched by Arianespace for Eutelsat.

With this latest launch, Arianespace continues to bolster its exceptional partnership with Eutelsat, a relationship that reaches back to 1983. More than half of the operator's satellites to date have been orbited by Arianespace. This relationship is set to continue, since Arianespace's backlog includes seven more Eutelsat satellites, to be orbited by Ariane 5 and Ariane 6.

Built by Maxar Technologies, EUTELSAT 7C is a high-power broadcast satellite for markets in Africa, Europe, the Middle East and Turkey. By significantly increasing power over Sub-Saharan Africa, it will make room for several hundred additional digital channels to support the region's rapidly expanding television market.

Built by Airbus Defence and Space, T-16 will provide high-power broadcast services to the continental United States, Alaska, Hawaii and Puerto Rico.

Arianespace has 21 more Airbus satellites in its launch backlog.

Arianespace confirms its leadership in the geostationary launch market
Today's successful mission once again illustrates the dependability of Arianespace to boost satellites into geostationary transfer orbit (GTO). With this launch, Arianespace has now orbited a total of 376 geostationary satellites, including 176 on Ariane 5. The European operator has 24 more geostationary satellites in its backlog of launch orders.

С космодрома Куру запустили ракету Ariane-5 с двумя спутниками связи

Речь идет о спутниках T-16 и EUTELSAT 7C

ПАРИЖ, 21 июня. /ТАСС/. Европейская ракета-носитель тяжелого класса Ariane-5 успешно стартовала в четверг вечером с космодрома Гвианского космического центра (ГКЦ) во Французской Гвиане. С ее помощью на земную орбиту выведены два телекоммуникационных спутника T-16 и EUTELSAT 7C. Прямая трансляция полета ведется на сайте компании Arianespace.

Продолжительность миссии VA-248 составила около 34 минут. После успешного старта в 18:43 по местному времени (00:43 мск) оба аппарата выведены на геостационарную переходную орбиту. Общий вес груза на старте составлял 10,6 тонны.

Первый спутник T-16 массой 6,3 тонны был сконструирован компанией Airbus Defence and Space для американского оператора связи AT&T. Он будет обеспечивать передачу данных в Ka- и Ku-диапазоне радиочастотного спектра и сможет работать на пяти орбитальных слотах (от 99 до 119 град. западной долготы). Сигнал будет передаваться на континентальной территории США, включая Аляску, а также в Гавайи и Пуэрто-Рико. Срок службы аппарата составит 15 лет.

Второй - EUTELSAT 7C, был создан калифорнийской фирмой Maxar Technologies для французской компании Eutelsat Communications, которая предоставляет услуги по ретрансляции теле-, радио- и других сигналов. Аппарат массой 3,4 тонны, снабженный передатчиками Ku-диапазона, расположится над семью градусами восточной долготы. Он призван повысить пропускную способность в африканском регионе южнее Сахары, а также в Европе, на Ближнем Востоке и в Турции. Предполагаемый срок службы - более 15 лет.

Это уже пятый запуск для Arianespace в этом году и второй - с использованием Ariane-5. Носители данного типа используются с 1996 года для вывода на околоземную орбиту средних или тяжелых спутников, ракета может одновременно запускать от двух до четырех аппаратов.

ЦитироватьAriane 5 lofts satellites for AT&T, Eutelsat
by Caleb Henry — June 20, 2019

SANTA BARBARA, California — A European Ariane 5 rocket successfully launched two communications satellites June 20.

The heavy lift launcher took off from Europe's spaceport in Kourou, French Guiana, at 5:43 p.m. Eastern, carrying the T-16 satellite for AT&T's DirecTV business, and the Eutelsat-7C satellite for French operator Eutelsat Communications.

The 6,330-kilogram T-16 satellite, built by Airbus Defence and Space, separated from the rocket's upper stage 28 minutes later, followed by the 3,400-kilogram Eutelsat-7C satellite from Maxar Technologies 34 minutes after liftoff.

The launch is the fifth this year for European launch provider Arianespace of Evry, France, and the second in 2019 using an Ariane 5 rocket. Arianespace is roughly a year away from the maiden flight of the next-generation Ariane 6, which is designed to be more cost competitive against vehicles such as SpaceX's Falcon 9.

AT&T's T-16 satellite is designed to operate from five different orbital slots, and will cover the United States. The satellite's launch comes some seven months after AT&T Communications CEO John Donovan said the company had already launched its last satellite.

In a statement to SpaceNews, AT&T said T-16 is the last satellite currently planned.

"This new satellite will replace several satellites that are reaching end of life," AT&T said. "We currently have no future planned satellite launches."

AT&T has been increasing its focus on internet streaming services as its satellite television subscriber base wanes. The company reported a loss of 544,000 "premium TV subscribers" from January to March 31, lowering the total count to 22.4 million.

For Eutelsat, today's launch brings additional capacity to Africa, Europe and the Middle East for a mix of television broadcast and internet connectivity services. Eutelsat, which operates a fleet of roughly 40 satellites, plans to co-locate Eutelsat-7C with the Eutelsat-7B satellite at the 7 degrees east orbital slot. The company will then move Eutelsat-7A to another location as part of its fleet optimization strategy.

Eutelsat-7C carries 44 Ku-band transponders, replacing capacity from Eutelsat-7A and expanding coverage at 7 degrees east by 19 transponders.

Eutelsat-7C is the first all-electric satellite from Maxar Technologies. The spacecraft will take close to four months to climb from a geostationary transfer orbit to the geostationary arc 36,000 kilometers above the Earth.

Maxar said in a statement that more than 30 spacecraft it built have used some form of electric propulsion, collectively topping 100,000 hours of thruster operation.

Electric propulsion requires less mass than chemical propulsion, but is a slower means of propelling a spacecraft. AT&T's T-16 satellite from Airbus has chemical propulsion for faster orbit raising, coupled with electric propulsion for station keeping.

In a speech following the launch, Paul Estey, Maxar's chief operations officer, said Eutelsat-7C is the first satellite to carry Maxar's more powerful second-generation lithium-ion power generation system. The satellite also carries a photonics payload to demonstrate technology for more efficient payloads in the future, he said. Photonics payloads have the potential to reduce spacecraft mass compared to current radio-frequency systems.

Arianespace CEO Stéphane Israël said the launch provider's next mission is July 5 using a Vega light-lift rocket. That mission will carry the first of two Falcon Eye surveillance satellites for the United Arab Emirates.
