Following a series of burns controlled by Ariane’s computer, the Sylda structure encasing the 3181 kg GSAT-16 was then jettisoned. GSAT was released into its own transfer orbit about four and a half minutes after the first satellite.

DirecTV-14, owned by DirecTV, will be positioned at 99°W longitude in geostationary orbit to deliver Ultra HD direct-to-home TV across the USA and Puerto Rico. The satellite has a design life of about 15 years.

GSAT-16 satellite

GSAT-16, owned by the Indian Space Research Organization, will be positioned at 55°E in geostationary orbit to augment communication services across India. It has a design life of 12 years.
The payload mass for this launch was 10 352 kg. The satellites totalled 9481 kg, with payload adapters and carrying structures making up the rest.

Flight VA221 was the 77th Ariane 5 mission.
