GSLV is a launch vehicle used to launch INSAT class of satellites (GSAT series) into Geosynchronous Transfer Orbits. It is a three-stage launcher with one solid rocket motor stage, liquid stage and one cryogenic stage. With its efficient cryogenic engine it could lift greater loads into space.
Significance of GSLV:
- Mastering space technology: Despite restrictions on dual use technologies, India has built & validated fully working highly complex cryogenic rocket propulsion system. Eg: GSLV-Mk II can launch much heavier satellites which weigh around 5000 kg.
- Space Research: Enables to launch space stations to much higher altitudes
- Commercial launch market: Compared to launch vehicles of other countries, it costs almost half to launch satellites with GSLV
- Self reliant in vehicle launch: With successful launch of GSLV-MKIII India could achieve complete self-reliance and with cheaper launches help the Indian exchequer.
- Good governance: Tele-education, tele-medicine, village resource centre, remote banking disaster management system etc. would benefit and in turn help provide efficient basic services to even remote parts of the country.
- Strategic significance: Will help insulate India from whims & uncertainties of global space launch market which is changing with shifting geo-political priorities.
