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. Contents 1 History 1.1 Loss of communication 1.2 Tracking of the satellite 2 References History 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. In the coming days, the scientists will fire the thrusters on board the satellite to manoeuvre it to a geostationary orbit at an altitude of 36,000 km from Earth. The new GSLV is different from previous ones as ISRO has accompanied the new Vikas engine that gives 6 % more thrust and 50 % increased payload carrying capabilities. The next generation engine, which powered the rocket 's second stage, has increased the payload capacity by 2.5 tonnes. ISRO also stated that the communication satellite would also provide services to the Indian Armed Forces. During the launch, ISRO tested a next generation high thrust Vikas engine, which powered the rocket 's second stage. The improved engine increased the payload capability of the vehicle. The second stage also had electromechanical actuation system replacing electrohydraulic actuation system to enhance the reliability of the rocket. Officials said any improvement done to the vehicle would be incorporated into GSLV 's future missions, including Chandrayaan - 2 planned for October 2018. The satellite 's six - metre wide antenna would unfurl once it is in space. The antenna, meant for S - band communication, is three times broader than those generally used in ISRO 's satellites. This feature will enable the satellite to provide mobile communication for the country through handheld ground terminals. The smaller antenna in other communication satellites require larger ground stations. While GSAT - 6A will complement GSAT - 6, ISRO sources said the satellite would also provide services to the Indian Armed Forces. GSAT - 6 has been providing satellite communication services since its launch on August 27, 2015. Loss of communication The first orbit raising maneuver for GSAT - 6A was carried out successfully on 30 March 2018 by firing the Liquid Apogee Motor ( LAM ) for 2188 seconds from 09 : 22 AM IST. The second orbit raising maneuver was carried out at 10 : 00 AM on 31 March 2018. As the satellite was on - course for its third and final orbit raising maneuver on 1 April 2018, communication was lost with the satellite. Efforts by ISRO are on to re-establish communication with the satellite. Tracking of the satellite Asserting that ISRO scientists have located GSAT - 6A, ISRO Chairman K. Sivan has hoped that contact with the satellite would be re-established soon. References ^ Jump up to : `` GSAT - 6A ''. Indian Space Research Organisation.
