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, 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.
