GSAT-6A, the second predominantly S-band communications satellite, is set to be launched from Sriharikota. It will complement GSAT-6, which has been orbiting since August 2015 at 83 degrees East longitude.
The 2,000-kg-class 6A, costing about Rs. 270 crore, is a great deal more than a routine communications satellite. It is designated for the use of the Armed Forces .
Why it is better than previous satellite?
A special feature of the GSAT-6A is its 6-metre-wide umbrella-like antenna, which will be unfurled in once it is in space. The antenna is thrice as broad as the antennas generally used in ISRO satellites. It will enable mobile communication from anywhere via hand-held ground terminals. Regular communication satellites with smaller antenna require much larger ground stations, said a former director of ISRO.
