how satellite circuit work i don't understand they make all part in india?
Even ISRO people do not know. All sub-systems, sensors, cameras, photovoltaic panels, antennas are available off-the-shelve from international market. They just make a suitable configuration according to budget and assemble/ solder them together. In Western countries many university students assemble satellites for their own use.

What do you mean by don't know? o_O
Even engineering students know about SAT circuits. ISRO buys them from international market because we lack production firms.
Anyway, ISRO is setting up two plants for making those part.
It will not only enable us to produce them indigenously at lower cost but for exports and a frequency of 12+ launches every year on average.

India, France to Develop Satellite to Help Study Climate Change


Prime Minister Narendra Modi and French President Francois Hollande are expected to announce on Monday a new project for joint development of a satellite to help study climate change and explore ways to manage and mitigate its impact.

The Indian Space Research Organisation (ISRO) and Centre National d’ Etudes Spatiales (CNES) may ink a deal for jointly developing the satellite after Modi’s meeting with Hollande on Monday.

“There will be a new project of space program in relation to observation and prevention of climate change,” France’s Ambassador to India, Francois Richier, told journalists in New Delhi.

He said the French president’s visit would also see several MoUs being inked by higher education institutions of the two countries.

Hollande will land in Chandigarh on Sunday to commence his second visit to India. He will meet Modi on Monday and will be the chief guest at the Republic Day ceremony on Tuesday. Richier said that threat posed by climate change would be high on the agenda of the meeting between the prime minister and French president.

They are expected to discuss ways to step up bilateral cooperation on joint research and development and technology innovation as well as diffusion of clean energy and efficiency solutions that will help in transitioning towards a climate resilient and low carbon economy.

Both Paris and New Delhi are of the view that the ISRO-CNES cooperation should focus more on use of space technology to respond to climate change.

The CNES is keen to step up its cooperation with ISRO as India was one of the first nations to deploy high-quality satellite capabilities in response to the need to manage its water resources and address food security issues posed by the threat of climate change as well as the increasing frequency and intensity of extreme climate events, officials said in New Delhi.

Two Satellites

India-France cooperation has already resulted in two satellites, which were jointly developed by ISRO and CNES and are now delivering precious operational data for climate study. While Megha-Tropiques, launched in 2011, is helping scientists to map cloud cover in three dimensions, Saral-AltiKa, launched in 2013, measures the surface height of oceans, lakes and rivers with millimetre accuracy, heralding new prospects for management of water resources.

On the occasion of Modi’s visit to Paris in April 2015, ISRO and CNES signed an agreement, which proposed cooperation in the areas of satellite remote sensing, satellite communications and satellite meteorology; space sciences and planetary exploration; data collection and location; operations of satellite ground stations and spacecraft mission management; space research and applications.

It covered the potential cooperation activities, such as joint earth observation mission, hosted payload opportunities and exploration of Mars.

India-France cooperation in space technology started with the setting up of sounding rocket launching facilities at Thumba in early 1960s and progressed through the development of liquid engines in the 1970s.

The Future of ISRO – Get more Private Industries Involved and Encourage Academic Participation

ISRO's Conception of the Human Rated Orbital Vehicle. design and testing of OV is in progress

by P.V. Manoranjan Rao

Former Chairman of the Indian Space Research Organisation Dr K Kasturirangan, on the future of ISRO, the need to interface with university systems as well as consortium of industries and the viability of an Indian human space mission.

It is time we start looking at ISRO in a very different perspective. We cannot go on producing satellites and launch vehicles which are operational within the system. Right now, our manpower is about 15,000 to 18,000 or that kind of a number; it should not grow more than 20,000 to 22,000 whereas the number of missions should grow by three to four times in the coming five to eight years. Obviously, this can come only if there is an external capacity that is built and the whole mechanism of institutionalising, and how to do it outside ISRO, are well planned and ensured. Industries have been meeting ISRO’s requirements very well. With proper policy framework for ISRO in place, the industry can be allowed to use our launch and test facilities. This is yet to take place. It’s not purely outsourcing.

Industries will have to get missions, get the stakeholders and user community and also do business with outside world. And for that, it has to be more than just being an outsourcing system. So you have to really create a parallel ISRO within the industrial system in this country. This is important.


Dr Kasturirangan

Yes, you need to focus on R&D, proof of concept missions, international collaborations, human space mission as and when it takes place, planetary programmes, etc. This should be all within the scope and the overall agreed programmes on space, which should be the mandate of ISRO. But the moment an operational system is created, a consortium of industries should come and take it over and also do business on that basis. So, that is what I would say should be the next attempt.

On frustrating Moments

Frustration comes in because you have expectations and you don’t meet those. Expectations from ISRO, particularly from outside, are great; many times it is difficult because people think that a great thing is happening in this country and they do not have a benchmark, so their expectations are high. Within ISRO, we know there is a gap between what we are capable of and what we are doing.

Then we get frustrated because we think that we should be doing more. Take for example remote sensing applications: in ISRO we have major centres doing this. We have operationalised some applications. We also have Regional Remote Sensing Centres. Very good. But when we see what systems like Google are doing, we know we are far from them. We should have gone ahead without any constraints on using remote sensing data.

The second thing is the non-proliferation of space science into the university system. I think we have got very limited interface with university systems. You look at planetary mission like Chandrayaan. How many university papers do we see? Practically nothing. It was not pushed with passion. Now Mangalyaan! It was called as a test flight for technology. I was amazed at the way in which these things are being said outside. Planetary mission is a planetary mission. You will have instruments with which we can do contemporary science. You’re going to have a new look at Mars with respect to its origin, its atmosphere, the climatology system, its implication with respect to Earth. This is the objective.

You need to have technology. Technology always is driven by science and this technology is always higher than the technology you need for day-to-day and down-to-earth applications. So this is the loop you should really look at. So please make sure that this is a correction you need to make when you talk about planetary missions. ISRO will not have a technology demonstrator for planetary missions. It will be always science that will drive it.

In the process it will develop new technologies. Those new technologies will further improve our ability to explore and at the same time used for improving remote sensing and other kind of satellite technologies for down-to-earth application. So this is the way we should look at planetary missions and make sure that we get an opportunity to demonstrate that we’re able to go there and do experiment. We’re qualifying ourselves into a global player and try to function in a consortium. If you’re part of a consortium, you should be an equal partner, because you are able to contribute, which you have demonstrated.

And lastly it is also the way in which excitement can be created in the younger generation. This excitement in younger generation is going to be a sustaining factor. Presently not a single university is involved in the Mangalyaan mission. Not a single academic institution is involved. We need to transform the planetary missions as intellectual opportunities even as we demonstrate our technological capability.

Should India go for Human Space Missions?

Yes, in the long run. I think three or four countries have done it. And countries with the resources today are able to do it. Among countries capable of doing it, India can be included. But on the other hand, if you ask me whether we have lost time, we’ve not really lost time, because we build up our applications at a certain pace. So we have a certain way with which we’ve gone about our programme. ‘You need one more ISRO! People give you a wrong impression about the type of resources needed for human space mission. The returns may not be commensurate with the type of money we put into. Returns will never be big. So we need to wait.’ That’s what I told Prime Minister Vajpayee when he asked me about human space flights. But that doesn’t mean that we need not prepare for it. We should certainly aim for increased stature as a spacefaring nation.

Look at the amount of work the US did before embarking on a human space mission there, with their space shuttle. You cannot imagine, the documents they prepared would fill a whole room. The number of scientists, number of engineers, number of strategic planners, the managers – all of them were brought together and separately each one of them churned the concept. That doesn’t mean that concept is applicable to India. You need to go through a similar exercise.

For if Chandrayaan took us four years, a human space mission will take five to six years to specify what the human space mission should be. Then how do you implement it? There are many ways of doing it. You can go on a totally autonomous way. That is number one. Or, try to find out all that is available elsewhere. Exactly like we build a satellite using the components which are available in the market, we don’t build the components. You do an exercise of that kind for human space mission and see what can be bought and what can be built indigenously.

A judicious option has to be exercised very carefully. This is number two. Or we get major subsystems of human space mission and build it, like the Chinese did for the first and second manned capsules. That is number three. And then the fourth one is by enlarging, that is, get a human space mission working from another country. Work on. Like what we did for first cryogenic stage. And then give the Indianness to it. So these are just four approaches to do that. Each one of them, you look at the feasibility, the political considerations, the national priorities, the resources that we need and the time we need.

Well, you are technically correct. My comment was out of frustration. Without manufacturing, how can we aspire to be a modern industrialised 1st world country? Apple does not manufacture. They outsource manufacture of their IT products to Chinese, Malaysian and other developing countries. But they make prototypes of a new product in-house..from scratch. On the other hand DRDO labs, ISRO largely function as Design Bureau/ Engineering drawing Houses. Remember manufacturing is infinitely more demanding than conceiving/ designing. That is why we make (?) Fighter Jets but can not locally make a CT-scan machine, LED panel or passenger-car gear-boxes. For every little thing we look for foreign collaborator, ToT etc

Well, you have a point and a very pertinent one at that.

Thanks for getting the drift
We should focus on skill development. Diploma holding engineers/ technicians working on shop- floors are the movers & shakers of manufacturing economy; not IITians.

We make Optical systems & photovoltaic panels here.
Those are not suitable for space applications. Cell Phone makers manufacture Li-ion batteries, but in sattelites entirely different batteries are used.

ANU to team up with ISRO to design multiple object tracking software
Acharya Nagarjuna University will team up with Satish Dhawan Space Centre- Indian Space Research Organisation (SDSC-ISRO) to develop a multiple object tracking software (MOTR) with functions ranging from missile tracking in defence to tracking of flight paths in airports.

The ANU has entered into a Memorandum of Understanding (MoU) with SDSC-SHAR to design the MOTR and it is the first university in the country to have a tie-up with SDSC-SHAR in designing indigenous radars. India is the fourth nation in the world, after the US, Japan and Germany to design MOTR, Principal, University College of Engineering, P. Siddhaih said.

He said that the ANU has been granted the project estimated to cost Rs.30 lakh with which it would provide high frequency structural simulator software.

“The software can also be used in tracking of submarine and satellite launching. We are using the Electron Beam Steering Technique for tracking of objects,’’ Dr. Siddhaiah told The Hindu on Monday.

The ANU would also collaborate with ISRO to implement high gain antennas and a radar system which would be simulated with the help of high-end work stations, Dr. Siddhaih added.

The electron beam steering would ensure that the antenna could be moved by electron beams.

Appreciating the efforts of Dr. Siddhaih in bagging the prestigious project, ANU Vice-Chancellor V.S.S. Kumar said that the university would extend its support to all research activities in science and technology.


University engineering college principal P. Siddhaih says the software can also be used in tracking of submarine and satellite launching
What they're working on appears to be the back-end components (software, algorithms and related systems) for the ISRO's MOTR radar.

This radar is a beast.



As it is prepared for trials, the MOTR is composed of an estimated 4,600 T/R radar modules capable of electronic beam scanning. The electronic scanning capability means that the MOTR, through its 12 m x 6 m (39.4 ft x 19.7 ft) radome, will be able to track its targets simultaneously in a 360° spherical range without having to rotate. Its design specifications also allow the MOTR to track a maximum of 10 objects at a range of up to 1,000 km (540 nm).

Some additional specs I pulled from old saved articles & forum discussions;

50 cm x 50 cm object size at a slant range of 1000 km
30 cm x 30 cm object size at a slant range of 800 km


If my maths aren't all bungled up, 50 cm x 50 cm equals a surface area of 0.25sqm.




^^The MOTR uses a liquid-cooling setup, just like my Gaming PC :p

France to partner Isro in Mars mission

France will partner India in its next Mars mission, which the Indian Space Research Organisation plans to launch in 2018.

French space agency, CNES on Monday signed a letter of intent with the ISRO for French participation in the next Mars mission. The details of the French proposal remains unknown.

A joint statement issued in the wake of the summit meeting between Prime Minister Narendra Modi and French President Francois Hollande says, both leaders "welcomed the announcement of collaboration through the participation of the Centre National d’etudes spatiales (CNES) in future space and planetary exploration missions of the ISRO.”

India’s first Mars mission was a technology demonstrator. Its success led to the planning of Mars-2 mission for carrying out more substantive scientific experiments. As the slot in 2016 is out of question because of the non-availability of a suitable launch vehicle, the plan is to have the second mission in 2018 when the reliable PSLV could be used. A lander and a rover is being thought of in the second Indian Mars mission.

In addition to the Mars programme, India and France signed agreements for a future earth observation satellite and putting French Argos-4 data collection payload in the Oceansat-3, which may be launched in 2018 to provide continuity of data for already established services in the area of oceanographic applications. The earth observation project is to have a joint thermal infrared mission.

The leaders expressed confidence that these missions would contribute significantly to the monitoring of environment, weather, water resources and coastal zones and further strengthen the partnership between the two countries.India and France currently have two joint payloads Megha-Tropiques and SARAL for studying tropical atmosphere and sea surface.

There is no way GSLV Mk-3 will be operational by next year. If it conducts atleast 1 test-launch this year (with fully-developed Cryo stage) and atleast 2 launches next year, then by mid-2018 it could be ready as an operational platform.

For Cdy-2 mission, Mk-2 is the best bet. We are yet to come across with the Mk-2 as a fully reliable launch vehicle. Will need 5 successive flawless launches for that to happen.

My dream is to see us land a Curiosity-sized rover on the Moon onboard GSLV Mk-3 within 2025, as part of either Cdy-3 or 4.

Nope, if you see launch frequency boost, we can launch it easily on LVM3.
There's just two more successful flights of LVM3 and it will become operational. :)

Indian Cryogenic Engine wouldn't have been a reality but for the largesse of a few friendly Russian Scientists. Read the full story here:

Please read my earlier replies on the thread.
There's mention of Chandrayaan 3&4 and 25 tonne capacity Delta IV like Indian Rocket officially by ISRO chief.
