Polar Satellite Launch Vehicle (PSLV)

Known as ISRO's workhorse.  PSLV is 1st Indian Launch Vehicle to be equipped with liquid stages. Uses to Launch satellites of lower mass(~1400 Kg).

Geosynchronous Satellite Launch Vehicle (GSLV)

Much more powerful rocket, carries satellite much deeper into space. Delivers communication satellite. Carries heavier satellites (~2200 Kg).

Launch Vehicle Mark III (GSLV Mk-III)

3-stage launch vehicle (2 solid and 1 stage comprising liquid and cryogenic stages) Mk-III versions have made ISRO entirely self-sufficient in launching its satellites.

Small Satellite Launch Vehicle  (SSLV)

Developed specifically for small and micro-satellites. It carries up to 500 kg of satellite , launch from Satish Dhawan Space Centre.

Augmented Satellite Launch Vehicle (ASLV)

Developed to augment the payload capacity compared to SLV. Since ASLV suffered repeated failures, it was dropped in favour of a new project.

Reusable Launch Vehicle (RLV)

Experimental program aiming to develop a reusable space vehicle. Its objective is to reduce launch costs through reusability, and cost-effective access to space.
