From ISRO FB page

Three big missions this year...

PSLV C22 with IRNSS 1 - the first navigation satellite in the Indian Regional Navigation Satellite System (IRNSS) scheduled to lift in May, 2013.

GSLV D5 with the India make cryogenic stage, lift off from the second launchpad in Sriharikota the same month.

And another PSLV will lift off with the Mars mission in October, 2013.

It is highly unlikely that ISRO will do 2 launches in one month. They require a minimum of 6-8 weeks between launches. On another topic does anyone know the progress of semi-cryo engine development?

ISRO has not reached that 'advanced' level so as to appear on Facebook. ( Dumb Railways have their facebook a/c ).

There are 3/4 Facebook spam pages which are utilizing ISRO logo.

ISRO has not bothered to reply whether they have official Facebook page. This in spite of my mentioning in my mail that I have spent nearly 35 years in ISRO.

Do they read mails?

^^^ Once I sent a email to incorporate a disc with names on exo planet missions like NASA does. never got a reply.
High time PSLV is renamed to something more meaningful. Its a showpiece of Indian aerospace engg and has gone well beyond and will go further than the polar orbit as its name suggests.

@ arvin
Yes PSLV has launched Geo-sync as well as Moon mission and as such the name POLAR is very misleading.

Chinese space program is simply copied and helped by Russians after soviet union collapsed. Not sure why people are discussing it. thei moon mission was a joke compared to CY-1 and quality and life of satellites such that ESA or european companies won't touch it with a proverbial 1000 ft pole.

The Indian Space Research Organisation is to build a remote sensing satellite, Cartosat-3, capable of taking images of the earth with a resolution of 0.25 metres.
In the ‘Notes on Demands for Grants, 2013-2014’ from the Department of Space, which forms part of the budget documents presented to Parliament recently, Cartosat-3 figures as a separate item with an allocation of Rs. 10 crores. “Cartosat-3 is an advanced remote sensing satellite with enhanced resolution of 0.25 metre for cartographic applications and high-resolution mapping,” the document said.
Should take tech from RISAT and have all day night capability. It should be disguised as civilian satellite but be put to use for military applications when in need.

All Earth Observation satellites should do the same.

Yes but both launch pads have never been used at the same time
Though ISRO has two launch pads at SHAR, it has only one vehicle assembly building. So, at a time only one vehicle can be built. So, a vehicle can be built and kept on a launch pad waiting, then the second one can be built on the second launch pad.Both vehicles can be lauched at the same time because they are independent, or with the same time gap as the assembling period.

I wonder, what is the use of having two launch pads when there are no two assembly buildings.

Each launch pad in ISRO is at considerable distance from other which include SLV-3 and ASLV ones. I dont think they are the same for multiple ones. Actually you can see them clearly from aircrafts flying from Chennai to Visakapattanam

I was only wondering why ASLV pad is always closed and not used for any launches. May be a short PSLV can be launched from there

Hello,
I was just reading through current-science mag issue and came across this quote regarding our Risat-1
The SAR is so sensitive to the interaction of wind with the ocean surface that, in addition to wind speed, patterns and structures within the atmospheric boundary layer produce identifiable surface imprints3. An algorithm has been developed for the retrieval of very
high resolution ocean surface winds, ocean wave spectra as well as detection of coastal and deep sea ships using RISAT-1 SAR data.
All special requests and events of importance in and around India are being covered.
I was just wondering if any one here could perhaps try to answer my query that
#1 if our Sat is able to spot only surface/surfaced ships or can detect submarines as well.
#2 Can Risat 2 do it given it has an X band array.

Thanks

Another quote from the same article :
Real-time detection of coastal as well as open ocean ships using SAR images provides a valuable aid for building a space-based surveillance system. From the SAR imagery ships can be detected by means of their intensity contrast relative to the immediate background.

PSLV C-22 launch from may has slipped into June:

http://www.indiatimes.com/technology/sc ... 66743.html

So this changes isro's schedule to one GSLV launch in may and a PSLV in June. This looks more feasible than two launches in one month as they claimed back in February.

Idia reaps vast economic gains from remote sensing: Report - The Hindu
Earth observation from space, or remote sensing, has dramatically touched lives and yielded economic benefits worth thousands of crores of rupees across common users each year, according to Earth Sciences Department Secretary Shailesh Nayak.

Citing a recent survey done by the National Council for Applied Economic Research, Dr. Nayak said applications based on Earth imageries taken from remote sensing satellites improved farm and fishing productivity among others and saved hundreds of lives from cyclones.

Estimated fishing benefits

The survey has estimated fishing benefits at Rs. 24,000 crore over the years and farming at Rs. 50,000 crore. Farm output rose by seven per cent due to accurate weather forecasts and cropping tips based on remote sensing.

“We converted satellite data into a simple product for the fisherman and the farmer. No other country has done this,” Dr. Nayak told a news conference held in connection with 25 years of remote sensing in the country. In the 10 years since the first Oceansat spacecraft was launched, 90 per cent of fishermen were using a remote-sensing product developed for them to locate potential fishing zones. The fishing community gained by being precisely guided to zones abundant in fish even as they saved time, fuel and ecological damage.

For the past four years about a quarter of farmers have used an agricultural forecast application called FASAL which gives them information on weather, fertilizer and crop practices.

Indian Society of Remote Sensing (ISRS) President and Director of ISRO’s National Remote Sensing Centre V.K. Dadhwal said public and private sector agencies last year used 70,000 remote sensing data products to create maps, assess mining areas and plan urban infrastructure. Over a lakh of data products were bought or used every year. “The economic benefit will be 10 times the cost of the spend on remote sensing satellites but we should consider the vast economic returns rather than data sale revenues,” he said.

Coastal regulatory zones use imageries as archival reference while large infrastructure projects also need them while applying for clearance from the Ministry of Environment and Forests.

First Navigational Satellite set to fly in June - The Hindu
Indian Space Research Organisation (ISRO) plans to launch the country’s first regional navigational satellite, IRNSS-1, in June, ISRO Chairman K. Radhakrishnan said on Saturday.

The remaining six spacecraft that form the regional navigational constellation may follow over the next 18 months after tests on the first one, he said on the sidelines of a symposium on remote sensing being held here.

IRNSS-1 is being assembled at the centre here {Bangalore} and is to be flown on the domestic PSLV-C22 rocket from Sriharikota. The navigational spacecraft are expected to provide a sub-continental system similar to the GPS and vastly improve location and movement on ground, air or sea when they are fully in place.

There would be 12 missions (including both satellites and launchers) in the next 12 months, said Dr. Radhakrishnan, who is also Secretary, Department of Space.

On the launcher programme, he said some tests were lined up for the long-pending indigenous cryogenic stage of the GSLV rocket. Its advanced version, the GSLV MkIII, is also in the works.

Prior to the launch of the GSLV-D5 this year, “we plan to move [the cryogenic stage] to Sriharikota by the end of April” after a second high vacuum test, he said.

Apart from IRNSS-1, three satellites were in the final stages of integration — the GSAT-7, GSat-14 and the advanced meteorology satellite INSAT-3D. GSAT-7 and INSAT-3D are planned to be flown on the European Ariane rocket around August and September depending on the schedule of the launch service agency Arianespace.

As for Chandrayaan-2 which is to place a lander-rover on the Moon in a joint venture with Russia, Dr. Radhakrishnan said he could not give details as ISRO was discussing the issue with Russia. As per the original plan, ISRO is to make the rocket and the orbiting spacecraft.

When the satellite guru calls - The Hindu
As the euphoria following the Right to Education (RTE) Act gives way to realistic appraisal, it brings into focus other areas of education in need of attention, like higher education. Educational Television, with its primary target audience of undergraduates, could be a significant driver of India’s knowledge society but it remains underutilised. Aggressive promotion by the government and more public recognition will help extend the reach of educational television. But more than anything else, the users must be prepared to make effective use of these services.

Three decades ago, the Satellite Instructional Television Experiment (SITE) opened up new vistas for education in our country. In the years following SITE, the government brainstormed and came up with a vision as astonishing for its time as Marshall McLuhan’s earlier one of a camel driver with a radio in the desert. A satellite and a television transponder would be the modern equivalent of the camel driver’s radio. Together, they would extend a universe of educational experience to all the remote people of our country.

The dream took shape when INSAT 2B was launched in 1983. Soon after, the UGC set up the Countrywide Classroom through Audio-Visual Research Centres (AVRCs) at six universities in different parts of the country. Production got off to a flying start, enabled by two developments — colour television, which came in with the Asian Games and video, which had already replaced black and white 16 mm film as the medium of production.

Three 20-minute programmes were needed to fill the one-hour noon-time slot allotted for UGC telecasts on Doordarshan. With the freedom to choose their subjects, producers opted for a mix of syllabus-oriented and enrichment programmes in the documentary format. But the AVRCs needed time to build reserves and so, for the first decade or so, production had to be augmented with programmes from abroad to meet requirements. By the mid-1990s, the media centres had built up a substantial corpus. But the unevenness in the quality of these programmes, now in Betacam broadcast-quality format, necessitated their review by a panel at Headquarters. Following the demand for more syllabus-oriented programmes, video-lectures were converted into multimedia e-content DVDs and their content perked up.

The number of AVRCs, now upgraded to Educational Multimedia Research Centres (EMMRCs) to reflect their expanding roles, has grown to 18. Their activities are co-ordinated by the Consortium of Educational Communication (CEC), in existence since 1993. The CEC is committed to “addressing the needs of Higher Education through the use of powerful medium of Television along with the appropriate use of emerging Information Communication Technology.” Edusat, launched in September 2004, further extended the reach of the Countrywide Classroom, providing for two-way videoconferencing, on-line multimedia, and video programming through over a hundred Satellite Interactive Terminals (SITs) and Receive only Terminals (RoTs) installed at sundry colleges and universities. Essentially, the Media Centres under the CEC constitute a network of co-operating individuals that includes planners, technocrats, scholars, production crews, students and teachers. When all their efforts are pooled, the scale multiplies dramatically. But are users reaping the benefits of this massive machinery to the extent possible and, if not, what can be done to extend the reach of educational television?

Inevitably, there is pressure on the EMMRCs to meet targets and deadlines for Gyan Darshan, launched in 2000, and the UGC-CEC’s 24-hour free-to-air Channel for Higher Education, Vyas. Coping with the narrow deadlines and production-related issues such as quality, accuracy of content and relevance to the target audience is something the creative teams at the Media Centres (MCs) have learnt to take in their stride. But poor visibility and a lack of appreciation for their work on Vyas is discouraging many of them. Issues related to the quality of programmes as well as to the accuracy of content and its relevance to the target audience have always been in focus. Marrying the cultures of two industries as disparate as Education and Media has never been easy but, with the right approach on both sides, it has been possible to bridge the gap to a certain extent. On-the-job training is fast-tracked for academics with a passion for their subjects and they learn quickly to adapt scripts for television.

But it isn’t always smooth sailing. Producers are finding it increasing difficult to woo talent as they find that faculty members on whom they have to depend for academic content are often not too eager to help, primarily because their efforts for the educational media do not get official recognition (from UGC, AICTE etc.), although they are compensated monetarily. This is a strange contradiction since universities vie for these EMMRCs precisely because they offer unlimited opportunities for exposure. At the annual UGC-CEC Educational Video Competitions awards are given for a variety of categories. But more than awards, the EMMRCs need to be strengthened academically and technically and given more official recognition and greater visibility through aggressive promotion. It has been suggested that the educational channels run by UGC, AICTE, IGNOU, and NCERT be made must-carry ones by the government to ensure better awareness of their work. This must-carry provision should be strictly enforced by the government.

There are other areas in need of attention. For one, the videoconferencing done through the Edusat network reaching students in the remote corners of the nation. This is sometimes found to be less than adequate as problems with connectivity interfere with two-way communication during interactive sessions. With regard to the e-learning facility, which is essentially the computer and network-enabled transfer of skills and knowledge, the government needs to match keenness to generate e-content with a well thought-out policy on delivery mechanism. Research Officers at the Media Centres do liaise with colleges for feedback from students and faculty, the principal stakeholders. The inputs are reviewed and, if required, incorporated into the e-content. But, unless a proper delivery mechanism for e-content programmes is put in place, Media Centres cannot have a real perspective on their efforts.

The National Viewership Survey conducted by the CEC in 2010 showed that the UGC-CEC’s educational programmes are being viewed by around 13 per cent of the total student population in higher education. Better coordination with educational institutions will ensure that more students and faculty are sensitised to these channels. While it is perfectly legitimate to have expectations from the government, ultimately, it is the entire community of learners from diverse social and cultural backgrounds including those still in college, who are at the hub of this vast enterprise. The onus is on them too; to take fuller advantage of this Promethean gift to higher education in our country.

Isro designing geo imaging satellite
The Indian Space Research Organisation (Isro) is designing a Geo Imaging Satellite (Gisat). The Gisat will carry a GEO imager with multi-spectral (visible, near infra-red and thermal), multi-resolution (50 m to 1.5 km) imaging instruments. It will be placed in geostationary orbit of 36,000 km.

The remote sensing satellites launched by Isro revisit the same area once every two to 24 days and acquire images of a geographical strip (swath) at different spatial resolutions (360 metre to better than 1 metre). Gisat will provide near real time pictures of large areas of the country, under cloud-free conditions, at frequent intervals. That is, selected sector-wise image every 5 minutes and entire Indian landmass image every 30 minutes at 50m spatial resolution.
An integrated palaeochannel map of River Saraswati has been prepared from the origin in Himalayas to the Rann of Kutch. The origin of the mapped course of the River Saraswati palaeochannel in North West India was linked to Himalayan perennial source through Sutlej and Yamuna rivers.

The government has made efforts to trace the origin of Saraswati river and has also constituted a committee for this purpose.

The work on delineation of entire course of river ‘Saraswati’ in North West India was carried out using Indian Remote Sensing Satellite data along with digital elevation model. Satellite images are multi-spectral, multi-temporal and have advantages of synoptic view, which are useful to detect palaeochannels.

The palaeochannels are validated using historical maps, archaeological sites, hydro-geological and drilling data. It was observed that major Harappan sites of Kalibangan (Rajasthan), Banawali and Rakhigarhi (Haryana), Dholavira and Lothal (Gujarat) lie along the River Saraswati.

The Minister of State in the ministry of Personnel, PG & Pensions and in the Prime Minister’s Office V Narayanasamy gave this information in reply to a written question in the Lok Sabha on Wednesday.

GISAT will be an interesting step forward. As the technology improves and we are able to get better resolution, it would mean we can watch any area on Indian sub-continent on near realtime instantaneous basis. The issue would be how quickly we can get the resolution down from 50m to 0.5m, (say 2020 time frame) and then to 0.05m (say 2030 time frame)

Across the universe: India, US mull co-operation in moon, Mars missions
India and the US have agreed to expand their cooperation in civil space activities ranging from weather and monsoon forecasting to cooperative space exploration work, including future missions to the moon and Mars.

The agreement between the two countries' space agencies, Indian Space Research Organisation and National Aeronautical and Space Administration (NASA) was announced Friday after a meeting of the US-India Civil Space Joint Working Group (CSJWG).

"Building on NASA's collaboration in India's highly successful Chandrayaan-1 lunar mission in 2008, NASA and ISRO agreed to explore further cooperative space exploration work, including future missions to the moon and Mars," a joint statement issued after the meeting said.

"To this end the CSJWG agreed to continue discussions in planetary science and Heliophysics to identify areas of potential cooperation," it said.

Continued progress is also being made in promoting compatibility and interoperability between the US Global Positioning System (GPS) and the Indian Regional Navigation Satellite System (IRNSS), the statement said.

Further work in this area will take place bilaterally and in multilateral bodies such as the International Committee on Global Navigation Satellite Systems, it said.

The two sides exchanged information on a range of space and other policy issues and noted ongoing efforts to open up new opportunities for collaboration.

Both sides confirmed the significant programmatic interest in, and scientific merit of, moving forward with the proposed NASA-ISRO cooperation in the L & S-Band SAR mission, or remote sensing techniques, the statement said.

At the opening of the meeting NASA Administrator Charles Bolden highlighted the impressive growth of US-India cooperation on a range of cutting edge projects from deep space exploration to the use of Earth observing satellites to promote sustainable development.

The Minister of State in the ministry of Personnel, PG & Pensions and in the Prime Minister’s Office V Narayanasamy gave this information in reply to a written question in the Lok Sabha on Wednesday.

does the indian meteorological service have the necessary 360' in doppler weather radars now to generate the kind of rapidly updated maps the weather.com channels show?
there was some talk of buying even a C130 or two to fly within storm systems...

some of the bread n butter linkages taken for granted in richer countries is still lacking here.

Good question, google revealed this site Doppler Radar Products. So yes we have US designed chinese manufactured doppler radars for accurate weather forecasting. Also click the "Radar Products on GIS " section on the left hand side and take a view of Indian dumbness.

"Dr. Susmita Mohanty, the founder of India’s first private space company, Earth2Orbit, wants India to claim bigger piece of the space-launch pie"

I have worked with the Americans, the Europeans, the Japanese and the Russians through NASA, Boeing and my two companies prior to Earth2Orbit. I feel India is sitting on a goldmine because we have a very accomplished government space programme. The PSLV, used to launch earth observation satellites, is one of the world's most reliable launch vehicles in its class and has had 19 consecutive successful launches. It can be easily turned into a thriving commercial vehicle and would give India access to a multimillion dollar market.

Despite interest from international satellite makers, like the ones we represent, there are two big challenges. First, ISRO launches only two PSLVs a year, when theoretically it can launch as many as six.

Antrix, ISRO's marketing arm typically flies small piggy-back satellites for foreign clients using the residual space not taken up by its domestic satellite. I have met with officials from these agencies to convince them to pursue dedicated launches for international clients. They are starting to warm up to the idea, but lack the commercial mindset necessary to go after the market aggressively.

Our space policy needs reform so we can have our fair share of the 170 billion dollar international space market. ISRO should focus on R&D while routine satellite and rocket building activities can be outsourced to private players. Commercial launches should be encouraged. I have clients willing to book entire launches. The revenue possibilities are spectacular.

Agreed we need to launch 4-6 PSLV and 2-3 GSLV in a year if we want to get a small pie of Global SLV market , Need to take care of production bottle neck where ever it exist , PSLV is a mature and reliable workhorse proven consistently on many counts now its just the question of upscaling the launches year after year.

Russia eyes more joint space projects with India

Igor Afanasyev, Dmitry Vorontsov
Russia and India share a long history of cooperation in space. India's first satellite was orbited by a Soviet Kosmos-3 rocket from the Kapustin Yar site on April 19, 1975. The first Indian to travel to space, Rakesh Sharma, flew with the Soviet Soyuz T-11 expedition in 1984. In the mid-1990s and the early 2000s, Russia supplied 12 KRB cryogenic third stages for the Indian GSLV rockets. The two countries continue to be strategic partners in space exploration, as confirmed by Russian President Vladimir Putins recent visit to India.

In the course of the one-day visit on December 24, 2012, Putin held talks with Indian Prime Minister Manmohan Singh and signed $ 5 billion's worth of pacts in a variety of fields. Although defense contracts account for the major part of this sum, the newly signed space-related agreements are of no less significance.

The most important of these is certainly the agreement to jointly operate the Russian Glonass satellite navigation system. Among other things, the deal secures India's independence from the US GPS system by enabling it to operate Glonass for civilian and military purposes. An earlier accord, signed in late 2011, granted the Indian military access to high-precision Glonass signals for the purpose of dramatically increasing the accuracy of its ballistic missiles (to within half a meter of the target, according to some sources).

Russian Deputy Prime Minister Dmitry Rogozin announced last year that India had been invited to join the Glonass development program on a parity basis. New Delhi accepted the offer; in November last year Indian Foreign Secretary Ranjan Mathai hailed it as "an important component of Russian-Indian space cooperation".

In the course of Putins visit an agreement was reached on building Glonass signal correction stations in India to enhance the system's precision. Russia's satnav provider NIS Glonass, for its part, inked a deal with Bharat Sanchar Nigam Ltd. and Mahanagar Telephone Nigam Ltd. to jointly offer Glonass / GPS-based navigation services in India, using the Russian company's solutions and the Indian partners existing infrastructure. The partners are currently discussing the implementation of pilot projects in this area.

NIS Glonass in late 2012 registered a subsidiary firm in Mumbai with a view of setting up a software development office and a hardware production shop that would serve the Indian market. The company runs a showroom for potential customers and partners in Mumbai.

The prospects of the earlier announced bilateral interplanetary projects are less certain. The Chandrayaan-2 lunar exploration mission, originally scheduled for launch in 2014, suffered a delay due to the failure of Russia's Phobos-Grunt probe, which incorporated the same technology as the proposed Chanrdayaan-2 lander. "Chandrayaan-2, which is a joint program with the Russian Federal Space Agency, has been delayed due to some major reversals suffered by Russia in their launch vehicles, including their mission to Mars, last year," Parivakkam Subramaniam Veeraraghavan, director of Vikram Sarabkhai Space Centre, told the press on December 7, 2012. "The Russians have decided that they will give a lander, which is the most complex of the Chandrayaan-2 elements, only after flying the same at least once." In light of this circumstance, India's ISRO space research organization switched its exploration priorities from the Moon to Mars. India's first Martian mission is expected to be launched in October or November 2013.

Despite this development, Putin secured an agreement during his recent visit under which Russia and India will continue joint lunar exploration efforts. A mission is being tentatively planned for 2017 to launch an Indian rover and a Russian lander towards the Moon atop a Russian Soyuz-2 rocket. The lander and rover could spend up to one year studying the regolith and physical processes near the Moon's south pole.

India intends to invest about $ 3 billion in space exploration over the next five years. This hefty budget provides a good impetus for further cooperation between the two countries.
