In his inaugural address at the 23rd national convention of aerospace engineers with the theme — Infrastructure development for growth of civil aviation and aerospace technology in India — he said this technology will considerably reduce the cost of space projects and will give a better density impulse which makes it a ‘good candidate for the booster status.’

The cryogenic technology uses liquid hydrogen and liquid oxygen, whereas in the semi-cryogenic technology, pure kerosene (aviation-grade) will replace liquid hydrogen.
The GSLV-D3 would use indigenous cryogenic engine and stage — that the scientists were working on from 1996 — for the first time, he said.

This is a major milestone in the development of a sophisticated propulsion technology in the country.

The project was taken up for achieving self-reliance in cryogenic propulsion technology, following the technology denial regimes in early 1990s.

GSLV flights that India has launched so far have used Russian cryogenic stages.
Radhakrishnan added that ISRO was also getting ready for the static test of GSLV-Mk III, which is designed to launch four tonne satellites into geosynchronous transfer orbit. ISRO has already put in place infrastructure for development, testing and simulation of GSLV-Mk III, he said.
