India's future launch vehicle projects at a glance: VSSC director

[lit_soldier]

1. GSLV Mk2 payload increase to 3 tons. That would require changes to the CUS
2. More details on the SSLV
3. Repurposing the L40 stage to make a carrier vehicle for various test mission and spent stage recovery test missions. This will be a step up from the sounding rockets and the PSOM based carrier vehicles with larger capacity and throttle-ability.
4. Progress on the electric propulsion.

great initiative despite a lot of hardships and hurdles .

Most of the technologies like Electronic propulsion, Semicryogenic engine already developed and tested.

One of the wonderful pictures I must confess. What is also interesting is the fact that ISRO is working on a monstrous SC-400 engine as well that will have 4000kN of thrust perhaps! This will put India in the same league as big powers as far as the lift capacity is concerned.

What about 300 mN electric propulsion that will make a 6 ton into 3.5 ton!

That's to propel satellites in orbit. Nothing to do with lift.

All this is just repeating whats already available unless the cost factor is reduced by a factor of 2 to 3 times.
Except for telecom satellites in geo orbit and defense satellites , launch facilities are not very useful , since so many agencies are already offering them.
And i doubt any agency is in a profit except for the ESA.

Indian launch services are usually cheaper than ESA.

Apples and oranges. India cant launch 5 mt sats atm. Its all in the future.

But for the weight class which India can launch, there is no cheaper option available.

Not everybody develops 5ton sats.. most of the sats by countries are well below 2 ton.
as for ISRO they don't have any sats weighted above 4 ton... now with MK3 isro no longer rely on Ariane..

Mostly wrong.
Telecom sats in GEO are getting even heavier. Even india uses ESA for launching its 5 mt sats , even this year.
The profits in small and micro sats are neglegible and dont justify the investment in a space agency.
Nasaspaceflight is a good forum.Try it.

India's GSAT-20 scheduled to launch with in two months has 3.6 ton weight and it has 70 gbps capacity! Most powerful in Asia.

No they are getting lighter.

No they are getting lighter.

India is getting their but not quite.
Gsat11 to be launched by ESA this year.
Payload 5.7 mt.

No they are getting lighter.

They might get lighter but for that the chemical fuel will have to replaced by a ion propulsion engine .

As the chemical fuel for station housekeeping is nearly 1 to 2 mt of the payload.

1. There are no 5 tonne+ satellite operated by India ATM. One is planned however in 2018.
https://en.wikipedia.org/wiki/GSAT

2. After GSLV Mk3 there is only one satellite which is planned to be launched by ESA, ie, the GSAT-11. As you can see in the link above, rest all the GSAT satellites will be launched by ISRO itself. They are in mass range 3-3.6 tonne.

3. Antrix, the commercial arm of ISRO is actually a profit making organization which is in the business of launching smaller satellites only. Once GSLV gains a track record of successful launches, it will also be added with capability of 3.5 tonne. Beyond that, launching satellites indigenously has a massive cost saving because the money remains in the country itself.
