It features a 6 - metre (20 ft) unfurlable S - band antenna similar to the one used on GSAT - 6 . Around 17 minutes after lift - off, the three stage GSLV Mk. ll rocket flying on GSLV F08 mission successfully injected the satellite into a geosynchronous transfer orbit . </P> <P> GSAT - 6A is a satellite is launched to support the GSAT - 6 satellite which was launched in August 2015 by ISRO . GSAT - 6 satellite launched to improve the communication system, now with the GSAT - 6A launch the communication will be better . As two satellite were used in the communication system, so the communication will be two - way communication . The first satellite GSAT - 6 launched at the cost of ₹ 269 Crore and the second satellite launched at the cost of ₹ 147 Crore . In order to operate communication system by these satellites a 6 - meter (20 ft) unfurlable S - band antenna which is similar to the one used on GSAT - 6 has used . The size of S - Band antenna used in GSAT 6A is 3 times more in comparison with another satellite . Hence GSAT 6A will be more capacitive . As this satellite will provide mobile communication to India through multi-beam coverage . </P>

Isro has successfully launched gsat_6a satellite from which rocket vehicle
