Indian Space Capabilities

Why are you comparing to LM-3B? LM-5 is 14 tonnes, why are you afraid of the number? LOL.
Because, CE-20 is more comparable within its category.
LM-5 will be more capacle for comparison with next GSLV with semicryogenic stage
Full potential, ISRO don't even dare to launch at 4 tonnes for this first launch. Why? Your next 3 tonnes plus is still gonna be launched by Ariane. LOL
Why are you burning like LM. Total payload of last launch was ~3.6 Ton also last launch was a trial launch.
Take some chill pill

ISRO to flight-test kerosene-based semi-cryogenic engine by 2021

If things go as planned, the Indian Space Research Organisation (ISRO) will flight-test the semi-cryogenic engine, which uses refined kerosene as propellant, by 2021.
With the success of the Geosynchronous Satellite Launch Vehicle Mk-III (GSLV Mk-III), ISRO’s Liquid Propulsion Systems Centre (LPSC) here at Valiyamala is now focusing on the next level – the development of the much-delayed semi-cryogenic technology.
Unlike the cryogenic engine which uses a combination of liquid hydrogen (LH2) and liquid oxygen (LOX) as propellant, the semi-cryogenic engine replaces liquid hydrogen with refined kerosene (Isrosene as ISRO calls it). LOX will be retained as oxidiser.

“Various tests are in progress on the engine. Of the four turbo pumps in it, three have undergone tests at the ISRO Propulsion Complex, Mahendragiri. We plan to have the engine ready by 2019 end, the stage by 2020-end and the first flight by 2021,’’ S Somanath, director, LPSC, said.

LPSC had developed the cryogenic engine for the GSLV Mk-II and the much powerful one for the GSLV Mk-III. The idea is to replace the second stage of the GSLV Mk-III, which now uses a liquid stage, with the semi-cryo. The rocket will retain the cryogenic upper, third stage.

The advantage of inducting the semi-cryogenic stage is the payload capacity of the GSLV Mk-III will increase from four tonnes to six tonnes. Using refined kerosene as fuel has quite a few advantages: It is eco-friendly and cost-effective.

Also, unlike liquid hydrogen – which has to be stored at (-)253 degree Celsius, it is stable at normal temperature. The Union Cabinet had cleared the semi-cryogenic engine project in 2008 at an estimated cost of Rs 1798 crore. Although the idea was to develop the technology 2014, the project got delayed.

Semi-cryogenic engine uses refined kerosene as propellant

It’s eco-friendly and cheaper

The Union Cabinet had cleared the project in 2008

ISRO hopes to flight-test it in 2021

Engine to be ready by 2019-end
 
Both Ariane 5 and LM 3B have achieved their full potential. The MK3 is a new rockets and hasnt achieved its full potential yet. Once the Semi-cryogenic engine is operational its LEO capacity will go upto 15 t.

perhaps eventually

LM-5 will be more capacle for comparison with next GSLV with semicryogenic stage

according to your own post, no it wont

lm-5 gto capacity is 14 tonnes, making it second only to the delta IV heavy as the heaviest in-service launch rocket avalible

Except that Delta heavy costs over a third of a billion dollars to launch. It's not sustainable.

The useless rants are deleted accordingly and that actually makes difference that PDF is still hosting a large number of foreigners and provides friendly environment. Try to be productive and share knowledge with quality though, the usual copy paste and increasing the post count is not a big deal at all that every call center troll can do well. Rest about speaking of difference, there is a word called introspection.

Enjoy discussion.
 
It is ok if you want to delete this post.

I thought I would be learning something new but nothing. How about all of us needs to be grateful and stop creating troll fest without any instigation.

I maintained 90+ % content of my own.

As I said, report as such and move on. Admin/Mods takes action as needed and appropriately and banning requires different parameters including number of fraction. Warning is being issued once so that member can rectify and correct him/herself though efforts having no avail, the habitual turns into pink. So kindly continue with your discussion on topic. Enough for today.

Thanks.

ISRO, which needs nanosecond-level precision, will now have to pay NPL for time-keeping services

The National Physical Laboratory (NPL), part of the Council of Scientific & Industrial Research, is host of the most accurate clocks in the country, and the only agency in India authorised to maintain Indian Standard Time (IST). The NPL maintains accuracy of ±20 nanoseconds through the Primary Time Scale, an ensemble of five caesium clocks and one hydrogen maser. The rest of the world connects to these via tele-clocks, satellite links, and Network Time Protocol services (which, for example, reflect in laptops’ clocks).

Airports, Parliament, banks, the Indian Space Research Organisation (ISRO), in fact anyone who needs to synchronise their computers, connect to a hierarchy of servers that link back to that of the NPL, which provides accurate time — down to milliseconds — for free. Until now, that is.

“We are in the process of signing a Memorandum of Understanding with the Indian Space Research Organisation [ISRO],” Dinesh Aswal, Director, NPL, told The Hindu. “I cannot disclose the amount, but it will be an important revenue source.”


Unlike the rest of us, who are happy if our watches and devices are accurate to the second, the ISRO launches rockets and tracks satellites, which requires precision at the nanosecond level. “Only the NPL is equipped to provide that level of accuracy,” Mr. Aswal said. NPL is also discussing similar deals with the Air Force, SBI, Indian Railways, and the National Informatics Centre.

Fund crunch

Why has NPL decided to start charging for this service? Its parent, the CSIR, has a funds crunch. Out of its ₹4,000 crore budget, only 10%–15% is revenue. CSIR wants to increase that to 25% this year, and 50% by 2020, as The Hindu has previously reported, and has directed its labs to start generating more revenue.

The NPL is also looking at other ways to assert its monopoly. IST can be sourced from similar organisations such as the United States’ National Institute of Standards and Technology, but with varying degrees of accuracy. Earlier this year, the NPL asked government to mandate that Indian organisations exclusively set their time to NPL’s clocks. “All countries require their computer infrastructure to synchronise to their local times,” Mr. Aswal had told The Hindu in an earlier conversation “It would be a landmark service if Indian computers were also mandated to do so.”

‘We need to build capacities in the organisation and the country,’ says A.S. Kiran Kumar

For space-faring nations, a launch vehicle — such as the all-Indian GSLV-MarkIII that was first flown on June 5 — is a vital tool for placing spacecraft in the sky. For India, the MkIII can lift four-tonne satellites with double the power of the older MkII rocket.

In a short exchange over the phone, A.S. Kiran Kumar, Chairman, Indian Space Research Organisation, explains what the new big rocket’s success means and what lies next. Edited excerpts:

How important for you has been the maiden success of your new launcher, GSLV MkIII? Could you please explain it beyond its four-tonne-lifting power?
It is indeed a very significant development in the Indian space programme. It gives us a big push. We were short of this capacity for lifting our communication satellites. We had to go outside for our launches; and because of [the launch schedules of foreign space agencies] the pace at which we did our projects was getting affected. Cost was another deterrent for pushing things aggressively.

By achieving MkIII, we will be able to push confidently and launch many of our communication satellites faster and indigenously. We will do one more launch within a year and establish it systematically.

The cost benefit ?
I cannot give you the exact figures as they keep changing. But just to give you the example of last year’s INSAT-3DR, we were able to do both the satellite and launch it here for the cost of an earlier foreign launch.


What would be next in your launcher-related activities? What is their status, schedule and the funds they need?

First we need to consolidate the developments. Our immediate and main task remains how to streamline the realisation of our three launch vehicles PSLV, GSLV-MkII [two-tonne lifter] and the new GSLV-MkIII, sustain them and ensure the number of launchers we need to put the satellites in orbit. For MkII, our target is to do two launches a year. As it is, building its supply chain, managing it and ensuring the required supplies for it are all an effort. To that we will be adding the requirements for MkIII.

On the launch technology side, we will be looking at how to reduce the cost further — by adopting new mechanisms, materials and new capabilities. Including the reusable launch vehicle concept.


You mentioned reusable technology to save costs. Where are we in that?
Last year, we tried out the RLV-TD experiment [Reusable Launch Vehicle Technology Demonstrator]. We got a small, plane-like model to vertically land on water. Next we will look at landing it on the ground with a landing gear system. We are conceiving systems to work on the air breathing propulsion technology that will use atmospheric oxygen. For the present launch vehicles, we will look at recovering [and reusing] some parts.

What is essential today for ISRO?
To build capacities within the organisation and the country to meet the demands.

We have a significant shortage of satellites in space. If we have to roughly double the capacity of the spacecraft, we have to do as many launches and cost effectively. That is the prime driver.

Also, it is essential for a space agency to build new capabilities, constantly get new skills to do complex jobs and to do routine things better.
 
Guys,

I have been wondering whether India has video satellites, as in remote sensing satellite which can view real time video.

CARTOSAT-2D can perform this task but for any particular location with high resolution. Multiple locations with lower resolution.

And it shall be the second most powerful motor of its kind in the world.

This Capability is only made for special purposes hence nothing available in public media.
I got this information from personal sources at ISRO.
I can share much more details about it but I will not going to do so because of sensitive information.
By the way CARTOSAT-2C also have such Capabilities but with some limitations (which are found during surgical Strike missions , last year)

Yah until then, you still need to pay Ariane hundreds of millions to launch 4 tonne satellite. LOL
It's because, GSLV is still not in regular Production stage. The last launch of GSLV MK-III D1 was one of the developmental launch.
As soon as, it gets full green light, no Indian satellite (upto 4tonns) will take off on foreign rockets.
