India in Space Profits of Satellite Technology By SRINIVAS LAXMAN IT could not have been a more auspicious place to embark on an ambitious mission. The place was Mary Magdelene's church in Thiruvanathapuram and it was here that a group of aerospace scientists first gathered nearly 35 years ago to launch India into the space age. Over the years, new hi-tech laboratories and workshops sprang up in different parts of the country. Now the Indian space programme is ready to take a giant leap forward with three launches this year. They are the launch of the INSAT-3B satellite next month to be followed by the INSAT-3A during the middle of this year, both by the Ariane-5 rocket from Kourou in French Guyana. Tentatively slated for launch in June or July is the Geo-Synchronous Satellite Launch Vehicle (GSLV) from Sriharikota, near Chennai. The main significance of next month's INSAT-3B mission is that it is the first of five satellites to be launched under the third series of the INSAT programme. This satellite will essentially be for different communication purposes. The question being asked is why INSAT-3B is going ahead of INSAT-3A? Space officials say it is being done to cater to the immediate requirement of the C-band capacity which was depleted because of the INSAT-2D failure in 1997. Maintaining its tradition, Indian space missions will always remain application-driven attempting to improve the quality of life of the people of this country. Vikram Sarabhai, described as the father of India's space programme, said that the country's space projects must benefit the common man. He said: ``The question is not whether developing countries can afford space technology; the point is whether they can afford to ignore it.'' Impressive Record With this in mind, India took off into the space age, first with the launch of the Rohini and Centaur rockets, followed by the Satellite Launch Vehicle, which successfully placed a satellite in orbit. Then came the Augumented Satellite Launch Vehicle (ASLV), followed by the Polar Satellite Launch Vehicle (PSLV). This year comes the GSLV. Despite India being a new entrant to the competitive global space club, which hitherto was an exclusive preserve of a handful of countries, India's overall track record both in the field of rocketry and satellites has been impressive. This, of course, does not overlook the fact that it had its share of failures too, which needless to say can be expected in any hi-tech project. To cite a few examples, one recalls the failures of the ASLV and of the PSLV. But, these failed missions only proved to be a blessing in disguise because with a few changes here and there the subsequent flights were a resounding success. This endorsed India's claim to be growing global space power. Remember May 26, 1999? It was on this day India left a strong impact on the global space market by successfully launching two foreign satellites, one belonging to South Korea and other to Germany along with the country's own ocean-monitoring remote sensing satellite. All of them were launched by the PSLV. This successful mission has given the Indian Space Research Organisation (ISRO) enough confidence now to market its launchers abroad. The four-stage PSLV is a versatile launcher offering a payload capability in different orbit profiles. Sriharikota's proximity to the equator, moreover, gives a better payload weight advantage for any polar launch. Keeping this in mind, Antrix Corporation, the space agency's marketing agency has to embark on a tough strategy to ensure that India's multi-faceted space programme becomes increasingly commercial in the coming years. According to an US-based aerospace firm, global satellite makers plan to launch about 1,000 satellites until 2,009 at a total cost of about $ 75 billion. The world market for space products and services currently stands at about $ 10 billion. Of this, the share of communication satellites is expected to be about 30 per cent, launch services 20 per cent and remote sensing programmes five per cent. ISRO is aiming to secure about 20 per cent of the global share of remote sensing products. A lot now depends on the initiatives which will be taken by Antrix Corporation to garner a small percentage of the remote sensing market. Higher Orbit What is of significance is that the remote sensing products of the Indian Space Research Organisation (ISRO) are in great demand in different parts of the world. In fact, the Indian Remote Sensing Satellite (IRS-IC) which was launched by the Russians in December 1995 has been described as a jewel in the crown by the prestigious American aerospace journal, Aviation Week and Space Technology. The flight of INSAT-3B, INSAT-3A and the GSLV this year will take ISRO into a a higher orbit. Once the GSLV is declared operational, perhaps after three test flights, India's future INSAT satellites will be launched by this rocket and ISRO perhaps need not go to Ariane to launch its communication satellites. With a capability to launch the 2,500-kilogramme class of communication satellites, the GSLV must be ``sold'' to other countries for launching their INSAT-type satellites. Technically, the GSLV may prove a thumping success when it roars off the launch pad at Sriharikota. But, to become an economically viable project it has to launch communication satellites for other countries as well. The GSLV programme suffered a setback when the Americans pressured the Russians to dishonour the nearly $250-million cryogenic engine deal to ISRO. The unfounded fear of the Americans was that the sale of these engines violated the Missile Technology Control Regime. But, it is to the credit of the Russians that they brushed aside American objections and went ahead with the deal. The first few test flights of the GSLV will be powered by the Russian cryogenic engines. Work is currently on at Mahendragiri in Tamil Nadu for developing the Indian cryogenic engine. If this project goes on schedule then the future launches of the GSLV will be equipped with the Indian-made engine. Mission to Moon The cryogenic engine controversy makes one wonder whether ISRO could have avoided depending on a foreign country if it had started making these engines right from the beginning. Considering the capability of the ISRO scientists and engineers, the answer is yes. Some of the other projects which are expected to reach fruition are an unmanned mission to the moon for carrying out scientific studies and the launch of a series of remote sensing satellites with a variety of applications, including one solely dedicated to the field of astronomy. The space agency is also studying the possibility of a reusable launch. There is also talk of enhancing the capability of the PSLV in order to enable it put into orbit heavier satellites.
