Mission

The Geo-synchronous Satellite Launch Vehicle (GSLV) is designed to place satellites in Geo-synchronous Transfer Orbit (GTO). It adopts the flight-proven solid and liquid stages of ISRO’s Polar Satellite Launch Vehicle (PSLV) and a cryogenic upper stage. The second developmental flight, GSLV-D2, carries an experimental communication satellite, GSAT-2, with an augmented payload of 1800 kg.

Salient Features

GSLV, in its first developmental flight, GSLV-D1, carried a 1540 kg payload into GTO. For the second development flight, GSLV-D2, the payload capability has been enhanced to 1800 kg by incorporating:. Enhanced propellant loading in the core solid motor   . High pressure engine in liquid propellant strap-ons and the second stage   . Optimisation of structural elements
