India will launch its latest communication satellite, GSAT-7A aboard Geosynchronous Satellite Launch Vehicle (GSLV-F11) on December 19, 2018, from Satish Dhawan Space Centre at Sriharikota, Andhra Pradesh.
The GSLV-F11 is ISRO’s fourth generation launch vehicle with three stages. The launch vehicle, which is in its 13th flight, will inject GSAT-7A into a Geosynchronous Transfer Orbit (GTO).
1. GSAT-7A, which weighs about 2,250 kg, is the 35th communication satellite built by ISRO. It is configured on ISRO’s standard I-2000 Kg (I-2K) Bus.
2. The satellite with a mission life of eight years has been built to provide communication capability to the users in Ku-band over the Indian region.
3. The satellite will be placed in its final Geostationary Orbit (GEO) using the onboard propulsion system.
4. According to ISRO, GSAT-7A will take a few days after separation from the launcher to reach its orbital slot.
5. While four liquid strap-ons and a solid rocket motor at the core form the first stage of the launch vehicle, the second stage is equipped with high thrust engine using liquid fuel.
6. The Cryogenic Upper Stage forms the third and final stage of the vehicle.
