There are several types of orbit for a satellite around Earth but let us consider two commonly used orbits. They are Elliptical Orbit and Geo-Stationary Orbit. Satellites in an elliptical orbit moves around the Earth in a ellipse with the height ranging from 800 - 2000 km from the Earth's surface.
Geo-stationary Orbits form a perfect circle and the satellites in Geo-stationary orbits moves along with the Earth's rotation, i.e. the satellite seems to be in a fixed position as seen from Earth. The height of these orbits are approx 30,000 km from the Earth's surface.
It is impossible to reach 30,000 km using normal propellant. This is where a cryogenic technology is used. Without cryogenic technology ISRO cannot move further in their space ambition.
About 22 yrs ago, ISRO requested NASA for the cryogenic technology which was refused. The reason was NASA feared that India may use this technology for creating missiles. ISRO then asked Russia to provide but due to the pressure from NASA, Russia refused to give it as well. In the last 18 yrs, ISRO researched on this matter and they created their own technology without any external help hence being called as the ingenious technology.
Unfortunately, their first mission on cryogenic technology failed. GSLV-D3 which was launched on 15th April, met with a malfunction in its third stage. This does not mean that the technology was the failure. ISRO will continue to test this technology and I hope it will succeed the next time.
