Augmented Satellite Launch Vehicle (ASLV), was a 5-stage solid propellant rocket with the capability of placing a 150 kg satellite into LEO. This project was started by the Indian space research organisation(ISRO) during the early 1980s to develop technologies needed for a payload to be placed into a geostationary orbit. Its design is based on SLV. ISRO did not have sufficient money to fund both the PSLV programme and the ASLV programme at the same time and this lead to the shutting down of the ASLV programme. The payloads of ASLV were Stretched Rohini Satellites. A low Earth orbit (LEO) is an orbit in which objects such as satellites are below intermediate circular orbit (ICO) and far below geostationary orbit, but typically around 350 - 1400 km above the Earths surface. ...

The ASLV is actually a five-stage vehicle since the core first stage does not ignite until just before the 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 (Reference 70).
However, instead of obtaining a circular orbit near 400 km, the ASLV only achieved a short-lived orbit of 256 km by 435 km, not unlike the degraded performance of the SLV-3 launch of 31 May 1981 (Reference 71).
The all-solid-propellant ASLV was created by adding two additional boosters modified from the SLV-3s first stage and by making other general improvements to the basic SLV-3 four-stage stack.
The first launch of the ASLV, on Mar. 24, 1987, failed when the bottom stage of the core vehicle did not ignite after booster burnout.
The fourth ASLV mission in May 1994 successfully reached its programmed orbit of 434 km by 921 km with the SROSS C2 payload.
