Satellite Launch Vehicle or SLV was a project started in the early 1970s by Indian Space Research Organisation to develop the technology needed to launch satellites. The project leader was Dr. APJ Abdul Kalam who is the present President of India. SLV was intended to reach a height of 400 km and carry a payload of 40 kg. SLV is a four stage rocket with all solid-propellant motors. The first launch of the SLV took place in Sriharikota on 10 August 1979. The last launch of the SLV took place on 17 April 1983. SLV formed the basis of the ASLV.
