GSAT-6

  Things to Know About GSAT-6:- 

1)  GSAT-6 is India's 25th geostationary communication satellite and twelfth in the GSAT series including one in  2001, 2003, 2004, 2007 and 2014 respectively.  GSAT-6 will join the group of India's other operational geostationary satellites and it will provide communication through five spot beams in S-band and a national beam in C-band for strategic users.

2) The S-Band Unfurlable Antenna of six metre diameter is one of the advanced features of GSAT-6 satellite

3) This is the largest satellite antenna realised by ISRO and it is utilised for five spot beams over the Indian main land

4) Spot beams exploit the frequency reuse scheme to increase frequency spectrum utilisation efficiency.

5) The satellite's life expectancy is nine years.

6)GSLV-D6 is the ninth flight of India's Geosynchronous Satellite Launch Vehicle (GSLV). It is also the fifth developmental flight of GSLV. This is the third time the indigenously developed Cryogenic Upper Stage (CUS) is being carried on-board during a GSLV flight. GSLV-D6 flight is significant since it intends to continue the testing of CUS. GSLV is designed to inject 2 ton class of communication satellites into Geosynchronous Transfer Orbit (GTO).

7) This is the second time Isro flew the GSLV rocket with its own cryogenic engine, after the successful launch of similar rocket in January 2014 that put into orbit GSAT-14. It may be noted the second mission of GSLV during the last five years after two such rockets failed in 2010. One of the GSLV rockets flew with Indian cryogenic engine and the other one with a Russian engine.

8) GSAT-6 is also known as INSAT-4E
