BENGALURU: The country's heaviest communication satellite GSAT-11 has been placed in its designated geostationary orbit at an altitude of about 36,000 km after four orbit-raising manoeuvres, the Indian Space Research Organisation (ISRO) said today.
The space agency said in a statement that the orbit-raising manoeuvres were performed by firing the satellite's propulsion system for a cumulative duration of more than four hours.

"Finally home! The communication satellite has been positioned in its designated geostationary orbit (at an altitude of about 36,000 km) with final orbit-raising manoeuvre... Solar panels and reflectors have been successfully deployed," the space agency said.

Launch vehicle Ariane 5 VA-246, carrying GSAT-11 and GEO-KOMPSAT-2A (South Korea), had lifted off from the Kourou launch base in French Guiana in the early hours of December 5.

Post-separation, ISRO's Master Control Facility at Hassan, in Karnataka, took over the command and control of GSAT-11 and found its health parameters normal.

The 5,854-kg GSAT-11 will provide high data rate connectivity to users of the Indian mainland and islands through 32 user beams in Ku-band and eight hub beams in Ka-band, the space agency said.

"GSAT-11 will boost the broadband connectivity to rural and inaccessible gram panchayats in the country coming under the Bharat Net Project, which is a part of the Digital India programme," ISRO Chairman Dr K Sivan had said at its launch.

Mr Sivan said the Bharat Net Project aims at enhancing public welfare schemes like e-banking, e-health and e-governance, among others.


Here is The News From ISRO's Official Site:

Indian Space Research Organisation’s (ISRO) heaviest and most-advanced high throughput communication satellite GSAT-11 was successfully launched from the Spaceport in French Guiana during the early hours today.

The launch vehicle Ariane 5 VA-246 lifted off from Kourou Launch Base, French Guiana at 02:07 am (IST) carrying India’s GSAT-11 and South Korea’s GEO-KOMPSAT-2A satellites, as scheduled. Ariane 5 is one of three launch vehicles operated by Arianespace along with Soyuz and Vega.

After a 30-min flight, GSAT-11 separated from the Ariane 5 upper stage in an elliptical Geosynchronous Transfer Orbit. The achieved orbit was very close to the intended one.

The 5854-kg GSAT-11 will provide high data rate connectivity to users of Indian mainland and islands through 32 user beams in Ku-band and 8 hub beams in Ka-band.

“GSAT-11 will boost the broadband connectivity to rural and inaccessible Gram Panchayats in the country coming under the Bharat Net Project, which is part of Digital India Programme,” ISRO Chairman Dr K Sivan said.

The Bharat Net Project aims to enhance the public welfare schemes like e-banking, e-health, e-governance among others.

He said GSAT-11 will act as a forerunner to all future high throughput communication satellites. “Today’s successful mission has boosted the confidence of the entire team,” Dr Sivan added.

Post-separation, ISRO's Master Control Facility at Hassan in Karnataka took over the command and control of GSAT-11 and found its health parameters normal.

The scientists will undertake phase-wise orbit-raising manoeuvres in the days ahead to place the satellite in the Geostationary Orbit (36,000 km above the equator) using its on-board propulsion systems. GSAT-11 will be positioned at 74-degree east longitude in the geostationary orbit.

Subsequently, the two solar arrays and four antenna reflectors of GSAT-11 will be deployed in orbit. The satellite will be operational after the successful completion of all in-orbit tests.

In the last 21 days, ISRO successfully completed three satellite and two launch vehicle missions.
