SKY Brasil-1(also known as SKYB-1) will be the 10th satellite launched by Arianespace for the operator AT&T/DIRECTV. The most recent launch was on May 27, 2015, lofting SKY México-1 and DIRECTV 15 on the same Ariane 5. AT&T/DIRECTV, a world leading provider of digital television programs, will use the SKY Brasil-1 satellite via its DIRECTV Latin America subsidiary. SKY Brasil-1 is a high-definition television (HDTV) broadcast satellite. Weighing approximately 6,000 kg. at launch, it is fitted with 60 Ku-band transponders. SKY Brasil-1 will be positioned at 43.1° West, and will cover Brazil. The satellite was built by Airbus Defence and Space in Toulouse, France, using the Eurostar E3000 platform.


After Telkom 1 and Telkom 2 respectively launched in 1999 and 2005,Telkom 3S will be the third satellite entrusted to Arianespace by Telkom Indonesia, this time within the scope of a turnkey contract with Thales Alenia Space. Telkom Indonesia is an Indonesian state-owned company that supplies telecommunications, information, media and entertainment services (TIMES) to millions of customers throughout the Indonesian archipelago.


Telkom 3S will provide high-definition television services (HDTV), as well as mobile communications and internet applications. Positioned at 118° East, Telkom 3S will provide C-band coverage of Indonesia and Southeast Asia, while extended C-band beams will cover Indonesia and part of Malaysia.

It also is fitted with Ku-band transponders dedicated to national coverage. Telkom 3S was built by Thales Alenia Space in Toulouse and Cannes, France, using a Spacebus 4000B2 platform.
