The Augmented Satellite Launch Vehicle or Advanced Satellite Launch Vehicle (also known as ASLV) was a small-lift launch vehicle five-stage solid-fuel rocket developed by the Indian Space Research Organisation (ISRO) to place 150 kg satellites into LEO.^[1] This project was started by India during the early 1980s to develop technologies needed for a payload to be placed into a geostationary orbit.^[2][3] Its design was based on Satellite Launch Vehicle.^[4] ISRO did not have sufficient funds for both the Polar Satellite Launch Vehicle programme and the ASLV programme at the same time and the ASLV programme was terminated after the initial developmental flights.^[2] The payloads of ASLV were Stretched Rohini Satellites.^[4]
