About Small Satellite Launch Vehicle

• SSLV:
  • The SSLV was designed to be smaller, cheaper, and quickly assembled for commercial launches on demand.
  • The SSLV can place a 500 kg payload at a height of 500 km in the Low Earth Orbit (LEO), compared to 1,750 kg carried by PSLV.
• Significance:
  • A cost-effective launch vehicle with high launch frequency and quick turnaround capability. 
  • Option of multiple satellite mounting options. 
  • An innovative vehicle that can be assembled in just 72 hours. Instead of 60 days, SSLV will be assembled in three days; instead of 600 people, it will be done by six people.
  • Unlike the PSLV and GSLV, the SSLV can be assembled both vertically and horizontally.
  • The SSLV is intended to cater to a market for the launch of small satellites into low earth orbits which has emerged in recent years on account of the need for developing countries, private corporations, and universities for small satellites.
• Issues:
  • There is a need for ISRO to create a separate launch pad for the SSLV so that quick launches can keep happening.
  • Launch pad at Sriharikota can be used for the other ISRO missions. This will also reduce the turnaround time for SSLV launches.
• Protocol
  • The space agency usually declares a launch vehicle operational after two successful development flights.
• Additional Information
  • With the space sector being the domain of the government’s department of space, India accounted for less than 2% of the global space market.
  • The aim is to increase the share to 9%.
