EUTELSAT 7C Arrives in Kourou ahead of 20 June Launch

2-5-2019-va247-liftoff3

EUTELSAT 7C, Eutelsat Communications’ (Paris:ETL) newest high-power broadcast satellite, has arrived at the European Spaceport in Kourou, French Guiana where it will be launched as a co-passenger on an Ariane 5 rocket on 20 June.

Built by Maxar Technologies, the 3.4 tonne satellite will serve markets across Africa, Europe, the Middle East and Turkey through 49 36-Mhz equivalent Ku-band transponders. It will be co-located with EUTELSAT 7B at 7° East, increasing capacity for this dynamic neighbourhood by 19 transponders. EUTELSAT 7A will be relocated as part of Eutelsat’s fleet optimisation strategy.

The launch is scheduled for 20 June during a launch window opening at 21:43 UTC and closing at 23:30 UTC.

The satellite will go into full commercial service at the end of 2019 following all electric orbit raising and in orbit tests.

The AT&T T-16 and EUTELSAT 7C satellites are readied for Arianespace’s next Ariane 5 launch

The two satellite passengers for Arianespace’s upcoming Ariane 5 flight – AT&T T-16 and EUTELSAT 7C – are advancing through their payload preparation phases during parallel activity at the Spaceport in French Guiana.

Both are telecommunications relay platforms for operation by long-time Arianespace customers: AT&T, which provides mobile, broadband, video and other communications services to U.S.-based consumers; and Eutelsat, the Paris-based company providing satellite capacity to clients that include broadcasters and broadcasting associations, pay-TV operators, video, data and internet service providers, enterprises and government agencies.

Scheduled for liftoff on June 20, this mission is to mark the fifth flight in 2019 by a member of Arianespace’s launch vehicle family – which consists of the heavy-lift Ariane 5, medium-size Soyuz and lightweight Vega. It  will be the second this year using the workhorse Ariane 5.

Another dual-payload mission for Ariane 5

AT&T T-16 – produced in France by Airbus Defence and Space based on the Eurostar 3000 LX Hybrid platform – will occupy the upper passenger position in Ariane 5’s dual-payload configuration, to be released first during the launch sequence.

The photo at left shows AT&T T-16 during its fueling process, while at right EUTELSAT 7C undergoes its fit-check with the payload adapter that will provide the interface with Ariane 5 when integrated on the launcher.

This hybrid-propulsion-powered broadcast satellite can be operated from five different orbital slots (from 99 deg. West to 119 deg. West) following its deployment by Ariane 5, with a coverage area that will include the continental United States, Alaska, Hawaii and Puerto Rico. Its liftoff mass is estimated at 6,350 kg.

EUTELSAT 7C, a telecommunications satellite with all-electric propulsion, is to be 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 will weigh 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.

 

Launch window for VA248: June 20

  • Between 2:43 p.m. and 4:30 p.m. El Segundo, California, USA time
  • Between 5:43 p.m. and 7:30 p.m. Washington, D.C., USA time

MISSION
DESCRIPTION

With its fifth launch of 2019, and the second this year using an Ariane 5 vehicle, Arianespace will serve two world-class satellite operators by orbiting T-16 for AT&T (DirecTV) and EUTELSAT 7C for Eutelsat. Both spacecraft will be deployed to Geostationary Transfer Orbit (GTO).

In performing this 104th Ariane 5 mission – the 71st with an Ariane 5 ECA version – Arianespace confirms its full capability in the geostationary launch services market segment.

PAYLOADS

T-16
t16

T-16 is the 11th satellite to be orbited by Arianespace for AT&T (DirecTV), following SKY Mexico-1 and DIRECTV 15, launched together on an Ariane 5 in May 2015; and SKY Brasil-1, launched in February 2017.

T-16 was manufactured by Airbus Defence and Space and will provide high-power broadcast services in Ku- and Ka-bands. Being flexible, the spacecraft can be operated from five orbital slots (from 99° West to 119° West) and will cover the continental United States, Alaska, Hawaii and Puerto Rico. T-16 is designed for a lifetime of 15 years.

Airbus Defence and Space France is prime contractor for T-16, which will be the 130th spacecraft from this constructor to be launched by Arianespace.

There currently are 21 Airbus satellites in Arianespace’s backlog.

EUTELSAT 7C
eutelsat7c

EUTELSAT 7C will be Eutelsat’s 33rd satellite to be launched by Arianespace since the first mission at its service, which deployed EUTELSAT-1 F1 in 1983.

Eutelsat Communications is established in Paris, with offices and teleports around the globe. Eutelsat provides capacity on nearly 40 satellites to clients that include broadcasters and broadcasting associations, pay-TV operators, video, data and internet service providers, enterprises and government agencies.

EUTELSAT 7C is a high-power broadcast satellite for markets in Africa, Europe, the Middle East and Turkey. It is equipped with 49 36-Mhz equivalent Ku-band transponders and will be located at Eutelsat’s 7° East position, one of the operator’s fastest-growing video neighbourhoods, which already broadcasts over 500 TV channels, and serves anchor clients across the region.

By significantly increasing capacity over Sub-Saharan Africa, EUTELSAT 7C will make room for several hundred additional digital channels to support the region’s rapidly-expanding TV market.

More than half of Eutelsat’s satellites have been orbited by Arianespace.

Arianespace has seven other Eutelsat satellites in its order book for future launches.

EUTELSAT 7C was built by Maxar Technologies in Palo Alto, California. Maxar is a leading provider of innovative spacecraft systems with deep experience in building and integrating some of the world’s most powerful and comprehensive spacecraft.

EUTELSAT 7C will be the 66th satellite based on a Maxar’s platform to be launched by Arianespace. It will also be the 56th based on Maxar’s 1300 class platform to be launched by Arianespace.
