PSLV
|
GSLV
|
|
Polar satellite launch vehicle
|
Geosynchronous satellite launch vehicle
|
|
First launch in 1993
|
First launch in 2001
|
|
Can carry upto 1600 kg satellite
|
Can carry upto 2500 kg satellite
|
|
Used for launching Indian remote sensing satellites
(IRS) such as CARTOSAT, RISAT, OCEANSAT, RESOURCESAT
|
For launching Indian National satellites (INSAT)
such as INSAT 2E, 3A…., GSAT-2,8,12.
|
|
Latest version is PSLV-XL. Can carry upto 1750 kg.
It was used to launch Chandrayaan, RISAT and MoM
|
Next version is GSLV MK-3

|
* Can carry upto 4500-5000 kg satellites, such as
INSAT-4 class.
* Until now, we relied on EU’s Arianespace launch
vehicle to send those INSAT-4 satellites.

Stages of GSLV – Mark 3
First Stage – Solid Propellant
Second Stage – Liquid Propellant
Third Stage – Cryogenic Engine
GSLV MK-3 has multi-mission launch capabilities:
·
GTO (geo transfer orbit)
·
LEO (low earth orbit), Polar
·
Intermediate circular orbits.
·
Therefore it can be used for launching satellites into different
orbits, according to Mission requirement.
·
Thus, GSLV MK-3 will make ISRO a competitive player in commercial
launches of foreign satellites (and earn million$$).
