India Successfully lunched the GSAT-9 Satellite.
India Successfully launched communication satellite GSAT-9 also known as South Asia Satellite using its Geosynchronous Satellite Launch Vehicle (GSLV-F09) Rocket.
GSAT-9 is a New Delhi's Gift to the SAARC nation as committed by Prime minister Narendra Modi in during SAARC summit in 2014.
- GSAT -9 is a communication satellite which will provide different communication applications in Ku-band with coverage over SAARC Countries.
- GSAT-9 is configured with 12 Ku band transponders, with lift off mass of 2,230 kg and Its main structure is cuboid in shape built around a central cylinder with a mission life of more than 12 years
- South Asian countries can access atleaset one transponder in which they could beam their own programming
- Satellite will help in applications and services to south Asian countries in the areas of telecommunication and broadcasting applications.
The Geosynchronous satellite launch vehicle is designed mainly to launch the Communication Satellites into Geosynchronous transfer orbit (GTO).
ISRO has developed two version of GSLV, the first version of GSLV MK II has capacity to launch satellites of lift mass upto 2500kg into GTO and second version of GSLV MK III has capacity to launch upto 4,000 kg in GTO
About Geo-Synchronous Orbit:
Geo-synchronous orbit is located 35,786 kilometers(22,236 miles) above Earth’s Equator which is ideal site for monitoring communication, weather, and surveillance.
Satellites in these orbits appear to remain permanently fixed in same position due to its geo-synchronous nature, so it can be viewed from particular position from Earth.
