Advanced Satellite Launch Vehicle

Advanced Satellite Launch Vehicle

Augmented Satellite Launch Vehicle (ASLV) was the springboard to the advanced Polar Satellite Launch Vehicle (PSLV).

The ASLV was not a simple variant of the SLV-3 but a more complex vehicle. The ASLV is actually a 5-stage vehicle since the core first stage does not ignite until just before the 2 booster rockets burn out. The payload capacity of the ASLV is approximately 150 kg to an orbit of 400 km with a 47-degree inclination.

History

Three successive failures plunged the project into a crisis. ISRO scientist had to confront new technological challenges and one of the important design changes was the addition of the 2 strap on boosters attached to either side of the first stage. Strap on separation, bulbous heat shield, "closed loop" guidance system as opposed to the "open loop" guidance system of the SLV-3 and heat shield management and separation had to be adapted by the scientists. However, all the problems and new technological challenges were overcome with ISRO's customary resolve and zeal, and the important ASLV program crossed an important rubicon.Fact|date=March 2008
