GSLV (GEOSYNCHRONOUS SATELLITE LAUNCH 
VEHICLE)
Background of GSLV:GSLV is an expandable launch 
system operated by ISRO. 
First launch in 2001. First successful flight in 2003: 
successfully placed GSAT-2 in 2003. 
Main Purpose: GSLV was primarily developed to 
launch INSAT class of satellites into 
Geosynchronous Transfer Orbits. 
GSLV is being used for launching GSAT series of 
satellites.
Three Stage Launcher (GSLV-Mk-2) (one solid 
motor stage, one earth Storable Liquid stage, and 
one cryogenic stage)

Comparing Solid Fuels with Liquid Fuels 
A solid rocket fuel has its fuel and oxidant mixed together 
as fine powders and then pressed into solid cake. 
Key characteristics
Higher Thrust -> Higher force to launch the vehicle.
Less volume 
One time burn -> all fuel burns at the same time, i.e. once 
it has been lit it will carry on burning until it is used up. 
Produces a lot of smoke -> large particles when fired
