New breed of satellite set for Dec launch

Kalyan Ray

The first Indian high-throughput satellite GSAT-11 that will pack more data in the same spectrum space, is set for December 2016 launch.

It is a new breed of satellite that provides many times more capacity than conventional payloads using new technology.

Commercial high-throughput satellites like ViaSat-1 and EchoStar XVII provide more than 100 Gbit per second of capacity, which is more than 100 times the capacity offered by a conventional Ku-band satellite.

The GSAT-11 payload will provide a capacity of about 10 Gbps to render broadband connectivity in rural areas. Indian Space Research Organisation (Isro) plans for more such satellites in future.

Earlier this week, the Union Cabinet approved procurement of launch services and realisation of ground segment for GSAT-11 spacecraft at a cost of Rs 1117 crore.

With 32 high-power spot beams, GSAT-11 would provide high bandwidth VSAT communication.

Because of the 5600 Kg lift-off mass, the satellite will be launched by the French ArianeSpace rockets by 2016 end, Isro officials told Deccan Herald. The ground segment is being realised to address the rural communication requirements.

Almost at the same time, Isro will attempt to park another communication satellite in the 36,000 km geo-synchronous orbit, using the indigenous GSLV rockets.

If the experiment — and the follow up launches — are successful, then India in future would not have to shell out foreign exchanges to launch the heavy communication satellites.
