Can you provide me the specification of the Geosynchronous Satellite Launch Vehicle (GSLV) of ISRO or Indian Space Research Organisation?

[Rajkumar Agarwal]

The specification of the Geosynchronous Satellite Launch Vehicle (GSLV) of ISRO or Indian Space Research Organization is as follows:

Height : 49.13 m
Number of Stages : 3
Lift Off Mass : 414.75 tonnes
First Flight : April 18, 2001

TECHNICAL SPECIFICATIONS

Payload to GTO: 2,500 kg
GSLV's primary payloads are INSAT class of communication satellites that operate from Geostationary orbits and hence are placed in Geosynchronous Transfer Orbits by GSLV.

Payload to LEO: 5,000 kg
Further, GSLV's capability of placing up to 5 tonnes in Low Earth Orbits broadens the scope of payloads from heavy satellites to multiple smaller satellites.

Third Stage: CUS
Developed under the Cryogenic Upper Stage Project (CUSP), the CE-7.5 is India's first cryogenic engine, developed by the Liquid Propulsion Systems Centre. CE-7.5 has a staged combustion operating cycle.

Fuel : LOX + LH2
Max. Thrust : 75 kN
Burn-time : 720 sec

Second Stage: GS2

One Vikas engine is used in the second stage of GSLV. The stage was derived from the PS2 of PSLV where the Vikas engine has proved its reliability.

Engine : Vikas
Fuel : UDMH + N2O4
Max. Thrust : 800 kN
Burntime : 150 sec

First Stage: GS1
The first stage of GSLV was also derived from the PSLV's PS1. The 138 tonne solid rocket motor is augmented by 4 liquid strap-ons.

Engine : S139
Fuel : HTPB
Max. Thrust : 4700 kN
Burntime : 100 sec

Strap-on Motors
The four liquid engine strap-ons used in GSLV are heavier derivatives of PSLV's PS2, and use one Vikas engine each.

Fuel : UDMH + N2O4
Max. Thrust : 680 kN
Burntime : 160 sec
