Satellite Launch Vehicle

SLV Overview:

     SLV - Satellite Launch Vehicle or SLV-3 was India's first experimental satellite launch vehicle. It has four stages which are all powered by Solid Propellants weighing 17 tonnes of propellant. It was about 22 meter height and has a capability of placing 40 kilograms class of payloads into Low Earth Orbit (LEO).

History and Success:

     Satellite Launch Vehicle - 3 was successfully launched on 18th July 1980, from SHAR (Sriharikotta Range), when Rohini Satellite, RS - 1 was placed in orbit, thereby making India - the Sixth member of exclusive club of Space-fairing nations. SLV - 3 employed an open loop guidance ( with stored pitch programme ) to steer the vehicle in flight along a pre-determined trajectory. 

Launch History:

     The first experimental flight of SLV - 3 was performed in August 1979, which was only a partially successful. Apart from the launch in July 1980. There were two more launches held in May 1981 and April 1983, orbiting the Rohini Satellite carrying remote sensing sensors.

Success Key for Advanced Launchers:

     The Successful culmination of the SLV-3 project showed the way to advanced launch vehicle projects such as the  
  • Augmented Satellite Launch Vehicle (ALSV)
  • Polar Satellite Launch Vehicle (PSLV)
  • Geosynchronous Satellite Launch Vehicle (GSLV).
