GSAT

The GSAT satellites are India's indigenously developed technologies of communications satellites, used for digital audio, data and video broadcasting. As of November 2015, 13 GSAT satellites have been launched by ISRO.

History

The GSAT series of geosynchronous satellites is a system developed by ISRO with an objective to make India self-reliant in broadcasting services. The repertoire of 10 GSAT satellites, a total of 168 transponders (out of which 95 transponders are leased out to provide services to the broadcasters) in the C, Extended C and Ku-bands provides services to telecommunications, television broadcasting, weather forecasting, disaster warning and search and rescue operations.

GSAT-9

GSAT-9 is a multi band communication and observation satellite planned to be launched by ISRO in 2017 by a GSLV rocket. The satellite will carry GAGAN navigation payload that will provide GPS services to the security forces and air traffic control organizations. GAGAN is a regional GPS navigational system developed by India. The satellite will have a mission life of 12 years

Satellite

GSAT-9 will carry 12 Ku band transponders and GAGAN payload. The satellite is planned to be launched in March-April 2017 by GSLV. The standalone satellite will have a liftoff mass of about 2,330 kg.

Satellite would use electric propulsion for station keeping.

Payload

The satellite will carry GAGAN payload and 12 K_u band transponders that will be built at Space Applications Centre in Ahmedabad. The payloads will cover the entire country including Andaman and Nicobar Islands.

Launch

The satellite is planned to be launched in 2017 with GSLV rocket.

INSAT-4E

INSAT-4E, also known as GSAT-6, is a member of the INSAT family and is a multimedia communication satellite that will offer a Satellite Digital Multimedia Broadcasting (S-DMB) service across several digital multimedia terminals or consoles which can be used to provide information services to vehicles on the fly and to the mobile phones. The satellite can be used for other social and strategic applications.

Satellite

INSAT-4E has five C x S transponders each of 9 MHz bandwidth and five S x C transponders each of 2.7 MHz bandwidth which will together cover the entire country.

Launch

ISRO successfully launched INSAT-4E on 27 August 2015, using a GSLV D6 Mk.II rocket flying from the Satish Dhawan Space Centre and inserted into a Geostationary Transfer Orbit (GTO) with injection parameters of 170 km x 35945 km, 19.96 degree inclination.

Orbit raising

Maneuvers to move the satellite into its designated geosynchronous orbit at 83 degrees East longitude were initiated on 28 August 2015 by firing motors on-board the GSAT-6 satellite.
