EDUSAT, an exclusive satellite for educational purposes, will be put into geo-stationary orbit during the third experimental flight of GSLV-3.

Estimated to cost Rs 90 crore, the EDUSAT will become operational by 2005. Preparations are also on for the establishment of ground infrastructure and the software needed for the distance education programme as well as for the setting up of a satellite-based Education authority.

The Indian Space Research Organization (ISRO) recently established for the Andhra Pradesh government an exclusive educational network utilizing the INSAT-3B's k-band transponder.

This network provides six exclusive channels for primary, secondary, higher education, technical education and e-governance.

Meanwhile, the cryogenic engine for the upper stage of GSLV underwent successful tests at the Liquid Propulsion Centre, Mahendragiri in Tamil Nadu.

The second flight of the GSLV is quietly getting underway for launch sometime in March.

ISRO Building Knowledge Bank Satellite (India)

Chennai, Mar 14, 2003 (IANS) 

The Indian Space Research Organisation (ISRO) is working on a satellite project that will take educational material to remote and inaccessible areas, says the space agency's chief K. Kasturirangan. Education and expertise are at present concentrated in a "few islands of excellence", Kasturirangan noted at an award function at the Sathyabhama private engineering college on the outskirts of Chennai Thursday. 

The ISRO chief was conferred an award by federal Human Resource Development Minister Murli Manohar Joshi. Kasturirangan said the country was struggling to build a base of infrastructure and find good teachers due to lack of funds. At a time like this, ISRO's EDUSAT would help reach content to remote areas. The content could be for primary schools, high schools or colleges. The same satellite transmission facility could be used to reach lectures and study material from special educators and experts to inaccessible areas where quality education did not reach. Any institution could download the contents of the knowledge bank, he said. Kasturirangan pointed out that ISRO's maps and data had already become sought after products even in France and the U.S. --Indo-Asian News Service

 

ComCom: Our country is striving to reach 100% literacy, with reference to this objective could you highlight the silent features offered by EduSat in - Education  promotion?

EduSat (Education Satlite) is a powerful communication tool for emulating virtual class room in an effective manner. EduSat makes it possible to conduct virtual classes in remotest places in parallel. The teacher at the transmission end, virtually becomes available to all the receiving-end virtual class rooms. This process can help in overcoming shortage of trained teachers by providing in-service training to the existing teachers at block level, in a time bound program, in a most economical way.

ComCom: Our country has reached high level of technical competency in the area of space research etc. However there may be shortage of technical and trained man power to manage the numerous ground stations at the user-end and the maintenance support, what is the experience and the problem faced by such setups currently operating in the country with a limited objective? 


It would take some time for the users to get trained and use the EduSat more effectively. The problem would naturally arise due to geographic vastness and type of supports available at remote place. A  specially trained team provide will provide help where ever required. Whenever a new technology is introduced, the need for training is always there. 

ComCom: The growth rate of the technology is so fast that even before the project gets implemented, the technology gets cheaper and superior alternatives become available. Is the EduSat implementation flexible enough to take care of such factors, in its overall major designs? What's your view ?

Particularly electronics and computer technology are advancing at the speeds, the education institutions can not keep-up the pace. One can not wait for technology to mature, doing so would delay national development. Technocrats always plan for changes and leave enough scope to incorporate new ideas but still there is a limit to the flexibility that can be built in to any system. In spite of our taking all the steps in planning to avoid obsolescence and redundancy, We can not hope to be 100% successful in in safeguarding against obsolescence due to rapid development in technology .

COMCOM : What is the projected life cycle of EduSat? 

The EduSat has a projected life of 10 years.

ComCom: In case of technical failure of EduSat, what is the alternative, will there be fallback arrangements?

There are dedicated Satellites for different applications. There are common functions among them. Though it is planned  for a 100% utilization of  resources offered by each satellite, the unused resources from one dedicated satellite can be utilized, if need be for another application. Every venture has its inherent risks which must be accepted to utilize to technology.

ComCom: Do you think the benefits to be gained by EduSat would be able to over take the population growth and burden on the literacy mission? 

Population of  India is growing in a exponential rate. No doubt there is need to control and stabilize the population. But that is largely left to political will. One can only watch and see but population growth should not stop a country from attempts towards progress.

ComCom: Some schools like Delhi Public School and IGNOU are already experimenting with teaching through lessons prepared for distance teaching using multimedia, slides etc. In what respect the EduSat teaching would be different or better than that or EduSat program. Are there plans to integrate such efforts by independent institutions? 

The communication technology based teaching is a viable solution. Any institution which can afford and is willing to put the efforts and costs involved, can utilize the technology. But the technology is still quite expensive and state has to support the venture. Of course the country may look forward to the institution who have expertise in the related fields at the right time, for the better utilization.

ComCom: In your opinion, is the education sector geared to utilize the resources offered by EduSat? 

India has a good percentage of qualified and experience professionals. There is enough availability of technical man power. What is needed is willingness, seriousness and lot of effort to make the venture successful. If Technology is made available   many education institutions may come forward to utilize the same purposefully. 

ComCom: When EduSat is planed to be fully operational?

EduSat is being planed for mid 2005. 

ComCom: Will private institutions be allowed to utilize the EduSat resources freely?

It depends on the government policy. EduSat will be dedicated to Education. The main objective is to achieve  literacy and the  question is not the  contribution from different sectors.

Kalam dreams of space habitat

SRIHARIKOTA OCT. 10. The President, A.P.J. Abdul Kalam, came back `home' today, to the Satish Dhawan Space Centre (SDSC), Sriharikota, and inspected the new facilities at the spaceport, including the second launch pad, expected to be inaugurated in the near future. 'I was with you for decades. Today I am all the more happy for the reason that it is a homecoming for me," he said as the Indian Space Research Organisation (ISRO) personnel broke into thunderous applause.

Mr. Kalam marvelled at the facilities at the new launch pad and said that a Geo-Synchronous Satellite Launch Vehicle (GSLV) or a Polar Satellite Launch Vehicle (PSLV) could be integrated at the pad. This vehicle could be launched in a mere two days. "When I saw that (the second launch pad) I had a dream. In 2021, I will visit this great spaceport," he said. Mr. Kalam said he would be 90 then. "The range will give me a lift from one of the launchers to L-4 or L-5, the orbital points which move between the Moon and the Earth. And at this point, the gravitational force is minimum," he said. By 2021, he expects ISRO to have a habitat for human beings in space. "That habitat, I will visit and come back."

The President said that ISRO had made rapid strides and had very many achievements to its credit. He recalled a 15-year-old school student showing him the painting of all the Indian launch vehicles from the SLV-3 to the GSLV and asking him which he had built. Mr. Kalam said he and his team were responsible for the SLV-3. "The student laughed. He said, `O, uncle, you have done a small thing.' I also laughed with him because it indicates how ISRO has graduated from 1980 to 2000," he said and added that the former Chairman, Kasturirangan, was responsible for a decade of great progress.

But this was not enough, he said. The ISRO had a job on hand that of becoming a major catalyst in national development. It could contribute to furthering education, agricultural extension services and providing communication services. According to the ISRO Chairman, G. Madhavan Nair, the second launch pad is the state-of-the-art facility and will enable increased frequency of launches in addition to serving as a backup to the existing launch pad.

"The launch pad is universal as it has enabling provisions for PSLV and GSLV and the future advanced vehicles, the GSLV Mark III and beyond. The successful developmental flights of the GSLV has heralded the operational era for the 2000 kg class satellites to GTO missions from the Indian soil. We intend to launch the EDUSAT in the first operational flight of GSLV next year," he said.

The ISRO was also intensifying the development activities of the GSLV Mark III, the next generation launch vehicle. This will provide 4,000-kg capability at the Geo-Stationary Transfer Orbit. As part of this development, many facilities, including propellant plants would be augmented at SDSC, Mr. Nair said.

"The ISRO is also embarking on developing a host of new technologies required for its advanced air observations system, advanced communication system and towards development of reusable launch vehicles," he said. On the coming launch, he said the entire ISRO and its partners were participating in the PSLV C-5 mission.The C-5 will be launched from SDSC on October 17. Past and current senior officials of the space establishment, including the former Chairman and MP, Kasturirangan, and the Director, SDSC, K. Narayana, received the country's First Citizen.
