GSLV-F08 will be called as a successful ISRO operation. It carried GSAT6A communication satellite, which was launched from Satish Dhawan Space Centre (Sriharikota). The launch is said to be one more feather in ISRO’s cap.
This is because this carries the technique which is meant to be for home-made communication satellites. GSAT-6A satellite will be launched into the orbit within 17 minutes of rocket lift off.The launch of GSAT-6A gave rise to discussions throughout the country.
Many thought, it is an important step taken to intensify military ascendancy. However, for ISRO (Indian Space Research Organisation), it was quite like a run-through for the second mission for the moon.
The Launch Helpful for Future Missions
It was a crucial launch for ISRO, as it helped them detect various improvements in the critical systems which will be useful for future launches. Also, it’s a way to attract more of foreign satellites for rocket launches.
P Kunhikrishnan (Director, Satish Dhawan Space Centre) mentioned that “The launch vehicle demonstrated the capability of GSLV as an operational launcher. It was evolved as a workhorse”.
At 4:56 PM, the Geosynchronous Satellite Launch Vehicle launched for twelfth flight. The launch was finished with an indigenous cryogenic upper stage from Satish Dhawan Space Centre (Sriharikota, Andhra Pradesh).
It took a span of 17 minutes to inject satellite into geosynchronous transfer orbit by a three-stage rocket. The post-launch moments were full of joy and amusements.
Very shortly, the team of scientists will launch thrusters on board. The satellite will be maneuvered to a geostationary orbit which is 36,000 km away from earth. “This GSLV is not like any other vehicle. The importance of this mission is that we have enhanced the performance of the vehicle with an improved Vikas engine that has increased thrust by 6% thereby enhancing payload capability by 50%” as mentioned by ISRO chairman K Sivan.
Advanced Vikas Engine
At the time of launch, ISRO ran a testing on Vikas (Vikram Ambalal Sarabhai) engine which empowers 2nd stage of the rocket. This engine is responsible for an improved payload capacity of the vehicle.
The upper stage also consists if electromechanical actuation system which works in the place of the electrohydraulic actuation system. This improves the reliability factor of the rocket.
They are planning to introduce similar improved changes in Chandrayaan-2 which are scheduled for October 2018.
GSAT – 6A
GSAT-6A is much similar to GSAT-6 which is a highly capable S-band communication satellite.
The satellite is designed with an antenna which six-meter wide and opens after reaching the space. The antenna is much broader than those satellites which are generally used in ISRO satellite.
The purpose of this satellite is to deliver an improved mobile communication across the country with the help of ground terminals. Many other satellites are equipped with a smaller sized antenna which demands more ground stations.
GSAT-6A will be working along with GSAT-6 and it is also programmed to provide certain services to Indian Armed Forces.
The satellite will also provide a platform for developing technologies such as demonstration of 6 m S-Band Unfurlable Antenna. Ground terminals and network management techniques could be useful in satellite-based mobile communication applications.
GSAT-6 was launched on August 27th, 2015, and has been providing satellite communication services.
“We have slightly tweaked the configuration of GSAT-6 from the original one to suit the needs of strategic users,” ISRO’s then Chairman A.S. Kiran Kumar had mentioned after the launch of GSAT-6.
However, the two satellites became a subject of controversial argument as 90 percent of transponders were to be leased to Devas Multimedia by the ISRO’s commercial arm Antrix Corporation. It was a deal which was annulled in February 2011 on the grounds that the country’s defense needs had to be met.
