Mission: GSAT-6A launch 29th march 2018 News & Updates

[Sarkar]

The 415.6 ton GSLV rocket measuring 49.1 metre tall is scheduled to blast off at 4.56 p.m. from the second launch pad from at Indian rocket port in Sriharikota, 105 km from here. The GSAT-6A satellite will be put into orbit around 17 minutes after the rocket’s lift off.

It will complement GSAT-6, which has been orbiting since August 2015 at 83 degrees East longitude. The 2,000-kg-class 6A, costing about ₹270 crore, is a great deal more than a routine communications satellite. It is designated for the use of the Armed Forces and will not add any transponder capacity for general uses, according to sources in the Indian Space Research Organisation (ISRO).

The 6-metre-wide umbrella-like S-band’s antenna was developed by ISRO’s Space Applications Centre, Ahmedabad. The unfurl-able antenna, hand-held ground terminals, and network management techniques could be useful in future satellite-based mobile communication applications. GSAT-6A will also have a smaller 0.8-metre antenna for communication in the C band.

So INSAT 4A replacement?
Thought it would be the one but as it is not for civilian usage, there may be something else they have planned.

No, it has S band so sat based mobile communication, Strictly military stuff

With eye on lunar mission, ISRO to test high-thrust Vikas engine

The next generation Vikas engine developed by the Liquid Propulsion Systems Centre (LPSC) is being flown for the first time. LPSC director V Narayanan told Express that the improved engine would give a significant advantage in terms of enhancing payload capability.

“Usually, the chamber pressure is 58 bar, but with the use of high-thrust Vikas engine, we will achieve 62 bar, which is a 6% increase in thrust that gives us 70 kgs of additional payload gain in this mission. Right now, we are going to use the high-thrust Vikas engine only in the second stage. Basically, we are validating it.

For Chandrayaan-2 mission, we will be using five such engines aiming for a payload gain of around 250 kgs,” Narayanan said. The four strap-ons and second stage will be boosted with high-thrust Vikas engines; cryogenic upper stage will be loaded with enhanced propellants of 15 tonnes instead of current 12.8 tonnes and will be operated with 9.5 tonne thrust compared to the present 7.5.”

GSLV Mk-II successfully places communication satellite GSAT-6A in to orbit on Thursday, it will give Indian Space Research Organisation (Isro) and the Indian Armed Forces a shot in the arm. Isro will be testing certain critical systems that may eventually go into the country’s second lunar mission, and the satellite will enhance communication services for the Indian military.

No bro, it has totally 5 S band & 1 C band beam, but I don't know how many transponders available on that C band beam.

 

[SATFAN]

Great achievement. One more milestone in ISRO journey

I Think They Think Seriously About All Indian DTH Operators Also .

yes it has 1 C beam but I think this sat is not for civilian use
