Bangalore, Apr 2 (ANI): Indian Space Research Organisation (ISRO) chief K Radhakrishnan on Friday said India is preparing to launch a geosynchronous satellite launch vehicle, GSLV-D3, any time around April 15.

The GSLV-D3 is powered for the first time by indigenously developed cryogenic engine.

"Preparations are going on. The final reviews are also taking place. It could be any day from April 15 which is the first available opportunity," Radhakrishnaan said.

GSLV-D3 would carry on board GSAT-4 an experimental satellite in which ISRO is also testing some new instruments.

Rashakrishnan claimed that the development of the indigenous complex cryogenic rocket technology is a reply to technology denial regimes.

"Significance in terms of cryogenic technology development has been a marvellous thing", he said.

In 1992, India wanted to get the cryogenic engine technology from Russia, and the Americans put a sanction on that country not to transfer the technology. But Indian scientific community developed the cryogenic engine technology.

"This is a flight-testing of that indigenous cryogenic stage," Radhakrishnan added.

The ISRO is using indigenously developed Cryogenic Upper Stage (CUS) for the first time in GSLV-D3.

The CUS has undergone full flight duration test of 800 seconds successfully.

For the first time the ISRO is also trying electric propulsion system during the launch of GSLV-D3 instead of liquid fuel. The move would enable the agency to extend the life of satellites by couple of years. (ANI)
