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.

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.

EUTELSAT 7C undergoes its fit-check with the payload adapter that will provide the interface with Ariane 5 when integrated on the launcher. This activity was performed in the large S5C clean room at the Spaceport’s S5 payload preparation facility.

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.
