during 1960s , 1970s, india initiated own launch vehicle program owing geopolitical , economic considerations. in 1960s–1970s, country developed sounding rockets programme, , 1980s, research had yielded satellite launch vehicle-3 , more advanced augmented satellite launch vehicle (aslv), complete operational supporting infrastructure. isro further applied energies advancement of launch vehicle technology resulting in creation of pslv , gslv technologies.
satellite launch vehicle (slv)
status: decommissioned
the satellite launch vehicle, known abbreviation slv or slv-3 4-stage solid-propellant light launcher. intended reach height of 500 km , carry payload of 40 kg. first launch took place in 1979 2 more in each subsequent year, , final launch in 1983. 2 of 4 test flights successful.
augmented satellite launch vehicle (aslv)
status: decommissioned
the augmented satellite launch vehicle, known abbreviation aslv 5-stage solid propellant rocket capability of placing 150 kg satellite low earth orbit. project started isro during 1980s develop technologies needed payload placed geostationary orbit. design based on satellite launch vehicle. first launch test held in 1987, , after 3 others followed in 1988, 1992 , 1994, out of 2 successful, before decommissioned.
polar satellite launch vehicle (pslv)
status: active
the polar satellite launch vehicle, commonly known abbreviation pslv, expendable launch system developed isro allow india launch indian remote sensing (irs) satellites sun synchronous orbits. pslv can launch small satellites geostationary transfer orbit (gto). reliability , versatility of pslv proven fact has launched, of 2014, 71 satellites/spacecraft (31 indian , 40 foreign) variety of orbits. maximum number of satellites launched pslv in single launch 104, in pslv-c37 launch on 15 february 2017.

geosynchronous satellite launch vehicle (gslv)
status: active
the geosynchronous satellite launch vehicle, known abbreviation gslv, expendable launch system developed enable india launch insat-type satellites geostationary orbit , make india less dependent on foreign rockets. @ present, isro s second-heaviest satellite launch vehicle , capable of putting total payload of 5 tons low earth orbit. vehicle built india, cryogenic engine purchased russia, while isro developed own cryogenic engine.
the first version of gslv (gslv mk.i), using russian cryogenic stage, became operational in 2004, after unsuccessful first launch in 2001 , second, successful development launch in 2003.
the first attempt launch gslv mk.ii indian built cryogenic engine, gslv-f06 carrying gsat-5p, failed on 25 december 2010. initial evaluation implies loss of control strap-on boosters caused rocket veer intended flight path, forcing programmed detonation. sixty-four seconds first stage of flight, rocket began break due acute angle of attack. body housing 3rd stage, cryogenic stage, incurred structural damage, forcing range safety team initiate programmed detonation of rocket.
on 5 january 2014, gslv-d5 launched gsat-14 intended orbit. marked first successful flight using indigenous cryogenic engine (ce-7.5), making india sixth country in world have technology.
again on 27 august 2015, gslv-d6 launched gsat-6 transfer orbit. isro used indigenously developed cryogenic upper stage (cus) third time on board in gslv flight.
on 8 september 2016, gslv-f05 launched insat-3dr, advanced weather satellite, weighing 2211 kg geostationary transfer orbit (gto). gslv designed inject 2 – 2.5 tonne class of satellites gto. launch took place second launch pad @ satish dhawan space centre shar (sdsc shar), sriharikota. gslv-f05 flight significant since first operational flight of gslv carrying cryogenic upper stage (cus). indigenously developed cus carried on board fourth time during gslv flight in gslv-f05 flight. gslv-f05 vehicle configured 3 stages including cus similar ones flown during previous gslv-d5 , d6 missions in january 2014 , august 2015.
decade-wise summary of gslv launches:
geosynchronous satellite launch vehicle mark-iii (gslv iii)
status: active
gslv-mk iii launch vehicle. capable launch 4 tonne satellites geosynchronous transfer orbit. gslv-mk iii three-stage vehicle 110 tonne core liquid propellant stage (l-110) flanked 2 200 tonne solid propellant strap-on booster motors (s-200). upper stage cryogenic propellant loading of 25 tonne (c-25). vehicle has lift-off mass of 640 tonnes , 43.43 metres tall. according isro, payload fairing has diameter of 5 metres , payload volume of 100 cubic metres. allow india become less dependent on foreign rockets heavy lifting.
on 18 december 2014, isro conducted experimental test-flight of gslv mk iii carrying crew module, used in future human space missions. suborbital test flight demonstrated performance of gslv mk iii in atmosphere.
gslv mk iii-d1 carrying communication satellite gsat-19 lifted off second launch pad @ satish dhawan space centre in sriharikota on 5 june 2017 , placed advanced communication satellite geosynchronous transfer orbit 16 minutes after takeoff. gsat-19 satellite lift-off mass of 3136 kg, communication satellite of india, configured around isro’s standard i-3k bus.
