hey guys,great news,isro is to launch 3 weather forecasting satellites.

here check out this link and article:

AHMEDABAD: India will get sharper eyes to track ravaging cyclones and forecast monsoon when the Indian Space Research Organisation (ISRO) launches the indigenously built INSAT-3D and Oceansat-2 satellites next year.

"The INSAT-3D satellite will be one of the three weather satellites that ISRO will launch in the next couple of years," said Abhijit Sarkar, a scientist at the Space Applications Centre (SAC) of ISRO here.

"These three weather satellites will improve weather forecasts and will keep a track of phenomena like cyclones and monsoon," he added.

"INSAT-3D will be a geo-stationary satellite and will be launched in 2008," he said.

"It will carry two sensors: a high resolution radiometer which will monitor rainfall, sea surface temperature and cloud movements and a sounder which will give profiles of temperature and humidity," Sarkar remarked.

"This satellite will do the all-important tracking of cyclones that emerge from the Bay of Bengal and Arabian Sea," he said.

Geostationary satellites orbit the Earth's equatorial plane at a height of 38,500 kms. At this height, the satellite's orbit matches the rotation of earth, so the satellite seems to stay stationary over the same point on the equator.

This is ideal for making regular observations of cloud patterns and helps in detecting formation of cyclones, Sarkar explained.

"The INSAT-3D will also help in monitoring the path the cyclones might take and thereby predict the time and place of the land-fall (place where the cyclone hits land) of the tropical cyclone," Sarkar said.

"This will be of great help in issuing warnings and carry out timely evacuation before catastrophe strikes," he said.

Apart from the INSAT-3D, ISRO will also launch the indigenously built Oceansat-2 in 2008 which will play an important role in forecasting the onset of monsoon and its subsequent advancement over the Indian peninsula, he added.

"This satellite will have an Ocean Colour Monitor which will help identify potential areas for fishery. It will also carry radar scatterometer which will measure the sea surface level winds," Sarkar added.

"Through the measurement of these winds, the condition of the sea can be predicted which will help ships navigating through the region," he explained.

"The Oceansat-2 will be launched by beginning of 2008," the scientist added.

The third weather satellite called the 'Megha-Tropiques' is an Indo-French collaborative effort and will be launched in 2009 using a spacecraft built by ISRO, Sarkar said.

"Though the satellite is Indian, a large portion of the sensors have been built by the French National Space Centre (CNES)," he said.

"Megha-Tropiques (Megha meaning cloud in Sanskrit and Tropiques meaning tropics in French) is a polar-orbiting satellite dedicated to atmospheric research. It will also track systems which will give rain and collect climate-related information," Sarkar added.

hey guys,great news here,india is to set up a dedicated space university in keerla.

here check out this link and article:

THIRUVANANTHAPURAM: The Indian Space Research Organisation (ISRO) is planning to set up a space training centre or a university in Kerala to meet the shortage of space scientists.

Speaking to reporters here on Monday, ISRO Chairman G. Madhavan Nair said the organisation indeed was planning such an institute.

According to media reports, the proposed institute is expected to come up on the outskirts of the state capital on a 100-acre plot. It would be modelled on the lines of the Bhabha Atomic Research Centre in Mumbai.

One reason why ISRO is planning such an institution is that its Vikram Sarabhai Space Centre here faces a crisis due to large-scale retirement of staff members.

It was in the 1970s that large-scale recruitment was done. With most of the staff having either retired or on the verge of retirement, there is a crunch of experienced personnel.

Veteran space scientist S. Nambinarayanan, who retired seven years back after 35 years of service at the centre here, told IANS that setting up a space university should have been thought of long ago.

"I am happy to hear this (news of a proposed university). Better late than never. In the West, most universities have aerospace departments and here it is none," said Nambinarayanan.

Another reason for the crunch in qualified personnel is that the newly recruited engineers are picked up after a year or two by private companies.

"The salaries offered in the private sector for engineers who have some experience are very high. This is going to be a problem for ISRO and it is better that it sorts it out," he added.

hey guys,great news here ,indian space research organisation is to develop low cost launchers designed to use aviation kerosene as fuel and oxygen as the oxidiser.

here check out this link and article:

Close on the heels of success in the space recovery experiment, the Indian Space Research Organisation (ISRO) is all set to find out if kerosene can be used as an ingredient of rocket fuel in the future.

At its liquid propulsion systems centre, ISRO scientists will undertake research on a new type of semi-cryogenic engine where aviation grade kerosene can be mixed with liquid oxygen as fuel for deep space rockets, ISRO sources told Deccan Herald.

Typically a mixture of liquid hydrogen and oxygen is used as rocket fuel where the hydrogen works as the fuel and oxygen as the oxidiser. Aviation grade kerosene will be tried as the fuel while oxygen will continue to play its role in the new mixture. If the experiment is successful, then future space travel is likely to be less expensive.

For the research, the Finance Ministry has given an additional Rs 75 crores to the LPSC in the budget, a part of which will be spent on setting up new testing facilities in Tamil Nadu’s Mahendragiri. The LPSC has been given Rs 218 crore in 2007-08. Overall the space department’s allocation has gone up to Rs 3858 crore from Rs 2997 crore in 2006-07.

Allocations have been provided for, sources said, to develop a next generation remote sensing satellite that will be parked in the geo-stationary orbit of 36,000 km, to look at India constantly. The existing band of Indian remote sensing (IRS) series satellites is stationed in the polar orbit of 600-800 km.

“The biggest advantage of the next generation remote sensing satellite, Geo-HR, is that it gives high repetition rate. During a natural disaster, it can monitor it constantly and warn us with minute details,” sources said.

ISRO intends to come out with an advanced oceanographic satellite, Altika-Argos. For the development of Geo-HR and Altika-Argos, a provision of Rs 25 crore has been made.

In the wake of scientists’ approval for a manned deep space mission, ISRO has been given Rs 50 crore for carrying out the pre-project activities for the manned mission.

Heavier satellite

Rs 12 crore has been allocated to develop a heavier — more than four tonnes — communication satellite. The existing INSAT class satellites weigh between 2.5 to 3 tonnes.

The space agency’s budget for disaster management had been augmented by almost Rs 45 crore for development of synthetic aperture radar that has wide applications in remote sensing and mapping. The space agency will buy an aircraft for flying the radar.

The government has also sanctioned Rs 75 crore for setting up an Indian Institute of Space Science and Technology for improving the manpower availability in space science.

The institute plans to take 200 students in the beginning and will offer integrated M Sc and B Tech and degrees. The institute is planned to be functional from 2007-08 from Thiruvananthaparam.

hey guys ,great news here ,indian governement is to launch the gagan satellite navigation network early next year.

here check out this link and article:

NEW DELHI: Navigating through the Indian skies would soon become easy as the government plans to launch next year the ‘satellite-based’ navigation system, GAGAN (Global Navigation Satellite System-aided Geo Augmented Navigation), which is being developed jointly by Airports Authority of India (AAI) and Indian Space Research Organisation (ISRO).

India will enter 'big league' in the world aviation scene with the launch of GAGAN next year, civil aviation minister Praful Patel said here on Tuesday. “Having such an advanced system will launch India into the future. The next generation of technology would enable airports in handling large volumes of air traffic,” he said while inaugurating the International Civil Aviation Organisation (ICAO)'s Navigational Systems Panel meet.

The minister said that to handle the rapidly increasing air traffic there was an urgent need to upgrade technical skills. He said the GAGAN system would make Indian skies safe and secure at par with the best in the world. Similar systems, like GAGAN are being developed by the US, European Union and Japan.

AAI chairman K Ramalingam said the technology demonstration phase of the GAGAN system had ‘shown better than expected results’. The system was now being integrated with the geo-stationary satellite INMARSAT-4F1. “Encouraged by its initial success, it has now been decided to initiate the final operational phase, in which its coverage area will be extended to the oceanic airspace also,” Mr Ramalingam said.

Meanwhile, justifying the government’s decision to hike charges on airlines for peak-time operations at three major airports, Mr Patel said the burden would be offset by incentives during the non-peak hours. “This is not a permanent measure. It is a temporary step to tide over the problem of congestion till infrastructure to expand capacity of airports to handle heavy traffic is in place,” he added.

The ministry is working on a proposal to double the peak-time navigation and other airport charges to de-congest air traffic over Delhi, Mumbai and Bangalore airports from March 25, the start of the summer schedule. The charges could be halved between midnight and 0500 hours. The decision is likely to result in 10% to 15% rise in airfares during peak hours as airlines are likely to pass the burden to customers.

hey guys,great news here ,indian space research organisation is now planning an exploration to mars now.

here check out this link and article:

BANGALORE: Indian Space Research Organisation is studying a proposal on a mission to Mars and is confident of undertaking a trip to the Red Planet within five years of the Centre giving the nod, ISRO chairman G Madhavan Nair said on Wednesday.

"Our scientific community has come out with some outline of a Mars exploration. We are studying the proposal. If the proposal is interesting, we will pursue that", Nair told reporters here.

Nair, Secretary in the Department of Space and also Chairman, Space Commission, was asked on India's "Mars strategy" in the backdrop of China recently announcing it will launch a joint mission with Russia to the planet in 2009.

He rejected the view that India is being left behind in the "race for Mars".

"Nothing (we are not being left behind). Our rocket can go to Mars without any problem. The GSLV (the home-grown geosynchronous launch vehicle) can take about 500 kgs (satellite) to Mars", Nair said.

If the Mars project starts now, ISRO would be in a position to undertake the mission in 2012, he added.

According to the agreement between the Chinese and Russian space agencies, a small satellite developed by China would be launched along with "Phobos Explorer", a Russian spacecraft in 2009.

India plans to undertake an unmanned mission to Moon in March-April next year.

Bangalore-headquartered ISRO is also currently in the process of preparing a detailed project report for a manned mission which Nair said ISRO would be able to launch within eight years of approval.

hey guys great news here,the images from cartosat are finally available.

here check out this link and article:

ISRO on Wednesday released images from the satellite Cartosat 2 launched in January this year.

Cartosat 2 has sent back the detailed images of Bangalore, Hyderabad and Perth in Australia and the space agency is very pleased with the results.

"I am happy to report that the satellite is in perfect health and all the functions have been validated and we are completely satisfied with the quality of image which is being sent by Cartosat 2," said Madhavan Nair, Chairman, ISRO.

Cartosat 2 is the 12th in the Indian Remote Sensing series and will be used for cartography and will help with disaster management.

The images, which has a better than one metre class of imaging, would be used by the National Urban Information Systems. Initially 137 major cities would be mapped.

"This satellite we have designed and developed exclusively to meet the national requirement of a cartographic nature. If any other users want to use the images for their analysis it is up to them," said Nair.

Primary use of this satellite data is going to be urban planning, generating the cartographic map of the whole country and various types of applications for laying out the infrastructure and trying to look at water bodies and watershed development programme which we need.

ISRO stressed on the considerable civilian applications of the images, but clearly defence organisations would find such images very useful as well. But Nair was circumspect when it came to the defence applications of the satellite.

Next on ISRO's agenda is the launch of PSLV, carrying a commercial Italian satellite.

OCEANSAT-2 getting ready: Nair

Staff Reporter
ASTROSAT, the space observation system, may be launched in 2008-09

`GSLV Mark-III can put satellites of up to five tonnes in orbit'
`Innovative technology should be within everyone's reach'


PROUD ACHIEVEMENTS: ISRO Chairman G. Madhavan Nair going round the exhibition on `Strides in Indian Science and Technology,' before the valedictory function of the two-day media workshop organised jointly by ISRO and DAVP in Bangalore on Friday.  51; Photo: K. Murali Kumar

Bangalore: Before the end of this financial year, OCEANSAT-2, a new satellite to study oceans, will replace OCEANSAT-1, which is nearly at the end of its lifespan. "The next one will be more powerful and will be equipped with a scatterometer to study the sea surface," said G. Madhavan Nair, Chairman of the Indian Space Research Organisation (ISRO). The applications of this satellite include identifying fishing zones and weather forecasting.
Mr. Nair was speaking to presspersons on the concluding day of a workshop on "Communication strategies and delivery systems to promote science and technology among rural people" here on Friday.
He said that ASTROSAT, a satellite that will serve as a "space observation system", is ready for launch in 2008-09. "It will have the capabilities to observe and study various celestial phenomena such as the supernova and black holes, through the use of multiple wavelengths, such as ultraviolet, x-rays and gamma rays," he said.
Commercial launches

As for future commercial launches, Mr. Nair said after the success of its Agile mission, ISRO would be undertaking three more commercial launches within the next two years. "The three contracts are much in their final stages, and we hope they come through soon," Mr. Nair said.
On ISRO's move towards "total self-reliance", Mr. Nair said its Geosynchronous Satellite Launch Vehicle (GSLV) Mark-III would be operational by 2009. While the present GSLV could launch a payload capacity of 2.5 tonnes into the geosynchronous transfer orbit, with Mark-III, the capacity would go up to four or five tonnes. As for GSLV Mark-II, Mr. Nair said that ISRO was still developing its indigenous cryogenic stage and the test launch would take place in a few months.
Delivering his valedictory address, Mr. Nair said: "We have very pressing problems, from access to food and water to inefficiencies in health care and education. We do not necessarily need technology that is so sophisticated as to serve only 5 per cent of our population, but should focus on innovative technologies that are within everyone's reach."
He cited the example of desalinisation mechanisms developed by the Council of Scientific and Industrial Research, which had the capacity to provide a litre of drinking water for 5 paise.
Satellite technology had catalysed the communication revolution that India had witnessed in the last 30 years. "However, the dramatic changes taking place in our metros is not enough to realise dreams of reaching our development potential by 2020 since 70 per cent of India lives in villages," he said.
On the responsibility of the media, Mr. Nair said: "Television and newspapers seem to begin their news with accidents, move on to advertisements and end in obituaries. What are we trying to convey to people? We have had some important achievements such as launch of the BrahMos missile, one of the most sophisticated missiles developed in India. But it hardly received any attention." Without a scientific temper, there would be no progress in the country, said A.P. Frank Noronha, Deputy Director-General, Directorate of Advertising and Visual Publicity (DAVP). He added that a relationship between scientific institutes and the media must be forged, and that the developments in science should disseminated through a creative use of multi-media in rural areas.

Gagan air traffic management system integrated successfully with Inmarsat
19 June 2007

Paris: India's ambitious Gagan Air Traffic Management and Aircraft Navigation System is headed for final tests later on in the year, following the successful integration of ground-based centres across the country with the Inmarsat geo-stationary satellite. American defence major, Raytheon, performed the integration.​
The Rs644 crore project, is being jointly executed by the Indian Space Research Organisation and the Airports Authority of India, and is meant to provide augmented information for satellite navigation to aircraft flying over Indian airspace.
Meanwhile, Raytheon officials said the final technology demonstration test of the Gagan system would be conducted later this year.
"The integration of the systems is ongoing and the final test will be conducted this summer or in the third quarter of this year," Jack Costello, vice president of Raytheon's Network Centric Systems, said at the Paris Air Show.
Costello said that all tests, following the integration of the satellite with the uplink stations, had been completed successfully. Overland communications apart, the Gagan system also envisages providing information to aircraft for navigation over the seas bordering India, where it is difficult to provide conventional navigation signals.
According to officials, once the test is complete, Raytheon will work with ISRO and AAI for the complete implementation of the system.
The Gagan system will have eight reference stations, including centres in Delhi, Guwahati, Jammu and Port Blair, and a mission control centre in Bangalore.
According to Costello, Raytheon was keen on expanding its "very healthy partnership" with ISRO, in view of the growth of the satellite launch market in India.
Meanwhile, another Raytheon official, Walt Doran, president of Raytheon Asia, said the company was working on a mini-radio frequency payload that would be put by the US Navy onboard the Chandrayaan-I, India's first unmanned mission to the moon. The sensor package will map the permanently dark lunar polar regions and also look for potential water ice deposits.

hey guys,great news here ,it seems that the gagan satellite system is in the final stage od design and trials.

here check out this link and article:

NEW DELHI: Keeping pace with the burgeoning air traffic in the country, the Airports Authority of India (AAI) is moving ahead with several major measures to shift from ground to satellite-based communication, navigation and surveillance (CNS) systems to make the traffic flow smoother.

The public sector organisation, which has been designated by the International Civil Aviation Organisation (ICAO) to provide CNS services to planes flying over 3.8 million square kms of oceanic region apart from land mass of 2.2 sq kms, has already placed 40 Indian airports on satellite-based systems and would cover 40 more by this year end.

Besides this, it was already testing the prototype of the GAGAN system, jointly developed with the Indian Space Research Organisation, AAI Chairman K Ramalingam told a workshop on CNS and air traffic management (ATM) status in the country.

The ambitious Rs 644 crore GPS-based Geo Augmentation Navigation (GAGAN) project would provide augmented information for satellite navigation to aircraft flying over Indian airspace and the routes over the high seas, he said at a workshop organised by the Asia Pacific Aviation Media Association (APAMA) here.

India would be the fourth in the world after the US, EU and Japan to have such a sophisticated system.

For this purpose, the AAI has already acquired three KingAir aircraft fitted with the required equipment to test and calibrate the system, which is now being operated for trials through the INMARSAT.

The final technology demonstration test of the GAGAN would be conducted in the next few months and the system would be made operational by 2010, he said.

hey guys,check this article out,it gives some information about the indian space research organisations sub-orbital reiusable rocket test and the reusable rockets capabilities.

here is the link and the article:

The Indian Space Research Organisation (ISRO)has given details of ongoing work for its 2009 reusable launch vehicle demonstrator suborbital flight.
Launched on a 11.5m (38.3ft)-tall solid rocket booster and using 9,000kg (4,090lb) of propellant, the X-37-like 1,400kg vehicle is 6.5m long with a 3.6m wingspan. Flight apogee will be 67km (42 miles) and it has a downrange of 650km. The vehicle will splash down in the Indian Ocean.
To model the mission, ISRO has developed six degrees of freedom simulation software to encompass all the environmental conditions and flight dynamics. A scale model of the test vehicle's nosecone, with nine air ports for sensors to aid flight control, will be built for windtunnel tests.
The solid rocket booster is an existing design modified for this task. "The grain has to be modified to reduce the maximum dynamic pressure," says ISRO Vikram Sarabhai Space Centre's Ramesh Narayanan, speaking at the second european conference for aerospace and sciences in Brussels.
The booster will use its four control fins' adjustable tips to regulate ascent. The test vehicle will use a reaction control system to modify its attitude to descend initially at a 35° to 45° angle of attack. During flight, the vehicle will experience its greatest thermal load - 40W/cm2 (101.6W/in2) - 100s after launch.
For flight control within the atmosphere during descent, the vehicle has a body flap at the rear, a rudder on each of its two tail fins, and outer and inner ailerons. The rudders and ailerons both have a maximum deflection of +/-30°. The rudders will be used as speed brakes.

hey guys,great news here ,india is to launch the israeli spy satellite the techsar ,which is to be a synthetic aperture radar satellite.

here check out this link and article:

MUMBAI: India will launch a foreign satellite with a 'top secret' payload in September.

Although officials at the Indian Space Research Organisation are tight-lipped about the nature of the hush-hush mission, information obtained by TOI from other sources suggests that ISRO's proven four-stage Polar Satellite Launch Vehicle (PSLV) will carry an Israeli spy satellite called TechSar, weighing about 260 kg.

The lift-off will be from the space centre at Sriharikota. The launch will mark a crucial milestone in growing Indo-Israeli military ties and there's a likelihood that some of the secret images taken by TechSar will be made available to India.

Developed by the Israeli aircraft industry, it will be Tel Aviv's first satellite with what is known as a synthetic aperture radar (SAR). This will allow the satellite to see objects below which are extremely tiny. SAR is used by moving instruments like satellites over immobile targets and has wide applications in the critical area of remote sensing.

While ISRO officials confirmed the flight to TOI, they, however, maintained it was absolutely classified at this stage. All they would say was that it would be a "dedicated commercial launch for a foreign customer".

GSLV to be launched on September 1

T.S. Subramanian

Vehicle to put in orbit communication satellite —INSAT-4CR


Launch campaign going on quite smoothly, says Suresh, VSSC Director

INSAT-4CR already mated with the launch vehicle


CHENNAI: The launch campaign for the lift-off of the Geo-Synchronous Satellite Launch Vehicle (GSLV-F02) from the spaceport at Sriharikota in Andhra Pradesh is getting into top gear and the massive vehicle will ease into the sky at 4.30 p.m. on September 1.

The vehicle will put in orbit a sophisticated communication satellite called INSAT-4CR, weighing 2,130 kg.

“The launch campaign is going on quite smoothly. So far we have not faced any problem,” said B.N. Suresh, Director, Vikram Sarabhai Space Centre (VSSC), Thiruvananthapuram.

Nerve centre

The VSSC, the nerve centre of the Indian Space Research Organisation (ISRO), has built the three-stage GSLV-F02, which is 49 metre-tall and weighs 414 tonnes.

Three stages

The three stages of the vehicle were stacked up in the towering Vehicle Assembly Building (VAB) of the second launch pad at the Satish Dhawan Space Centre (SDSC) at Sriharikota.

The satellite INSAT-4CR has already been mated with the vehicle, which will be slowly wheeled on rails to the launch pad by the end of this week.

Dr. Suresh said this GSLV was identical to the previous GSLV launched on July 10, 2006.

The INSAT-4CR is also similar to the INSAT that was to be orbited on that day.

However, that GSLV flight failed and had to be destroyed in mid-flight 56 seconds after the lift-off from Sriharikota when it veered too much from its path.

The debris fell into the Bay of Bengal.

The mission failed because one of the four strap-on motors of the GSLV did not build up enough thrust.

The strap-on booster motors are powered by liquid propellants.

A Failure Analysis Committee headed by K. Narayana, former Director, SDSC, Sriharikota, concluded that the performance of the vehicle’s sub-systems, except one strap-on motor, was normal until 56.4 seconds.

Primary cause

The primary cause of the failure was the sudden loss of thrust in one of the four strap-on motors immediately after the lift-off at 0.2 seconds.

With only three strap-on motors working, the ability to control the vehicle was significantly curtailed, the committee concluded.

Finally, the vehicle broke up in bits and it was also destroyed in mid-flight by firing the explosives wired to the vehicle.

The Range Safety Officer on the ground at Sriharikota pressed the red “destruct” button and the explosives came to life.

A manufacturing defect in the particular strap-on motor doomed the mission.

Design changes

Top ISRO officials said no design changes had been made in the vehicle for the flight on September 1 because the liquid strap-on motors had performed flawlessly in many previous Polar Satellite Launch Vehicles and the GSLVs.

But quality procedures and inspection methods had been tightened for this fight.

DTH television

INSAT-4CR has transponders which will be used for direct-to-home (DTH) television service, video-picture transmission and telecasting news events on a real-time basis, using outside broadcasting vans.

hats off to isro, with the budget and technological sanctions that we had they still managed to get a commercial space program in place, these are the real heroes of our nation, the sad thing is they earn less than i do and work for pride only(hello pay commission).
