Geosynchronous Satellite Launch Vehicle abbreviated as GSLV, is an expendable launch GSLV uses major components that are already proven in the Polar Satellite Launch Vehicle (PSLV) launchers in the form of the S/S solid rocket . The difference between expected and actual inclination degree was 0. SLV that stands for Satellite Launch Vehicle, was a project started by the Indian Space Research Organisation (ISRO) and was headed by APJ. GEOSYNCHRONOUS SATELLITE LAUNCH VEHICLE(GSLV) About the Launch Vehicle. newer improved version with a higher chamber pressure is used here. The stage was derived from the PS2 of PSLV where the Vikas engine has.

Question corner: What is the difference between GSLV and PSLV?

When you look at their track records, it is easy to see that the PSLV is more reliable. The Times of India. January 01, Retrieved 1 July One of the main reasons why the GSLV has such an increased load is its utilization of pskv cryogenic rocket engine for its last stage.

GSLV has been used in thirteen launches to date, since its first launch in to the most recent on December 19, carrying the GSAT-7A military communications satellite.

Retrieved 15 December There is no need to resubmit your comment. Archived from the original on 9 August The second developmental flight replaced the S stage with S Retrieved 27 August Retrieved 30 March It used the same solid motor with tonne propellant loading.


Retrieved 22 September The GS2 stage is powered by the Vikas engine. To assist the first stage in lifting the differenc rocket, the PSLV has 6 strap-on solid rockets. Archived from the original on August 10, Apart from launching the remote sensing satellites to Sun-synchronous polar orbits, the PSLV is also used to launch the satellites of lower lift-off mass of up to about Kg to the elliptical Geosynchronous Diffdrence Orbit GTO.

Both rocket and satellite had to be destroyed over the Bay of Bengal after the rocket’s trajectory veered outside permitted limits. The chamber pressure in all liquid engines were enhanced, enabling a higher propellant mass and burn time. This article is closed for comments. Retrieved April 27, II [ edit ]. The launcher was declared operational after the second development flight successfully launched the GSAT-2 satellite.

Destroyed by range safety officer after loss of control over liquid-fueled boosters.

The cuboid-shaped GSAT-6 satellite includes a technology demonstrator S-Band unfurlable antenna with a diameter of six metre which will provide S-band communication services during its expected mission life of nine years. Madhavan Nair 25 July You can tell when the rocket changes stages because it would eject the previous stage then light up the next one.

The cryogenic rocket engine provides more thrust than conventional liquid rocket engines but the fuel and oxidizer needs to be super cooled in order to keep them in a liquid state.

Archived from the original on 6 January Indian satellite launch vehicle. Retrieved 27 April Betewen 29 March All subsequent launches have used enhanced propellant loaded S stage. Satellite is fully operational and full design life of ten years will be achieved.


The difference between expected and actual inclination degree was 0. It is discarded when the vehicle reaches an altitude of about km. Printable version Jan 1, 4: I is propelled using a Russian made KVD Medium Lift Launch System.

Due to their geo-synchronous nature, the satellites in these orbits appear to remain permanently fixed in the same position in the sky, as viewed from a particular location on Earth, thus avoiding the need of a tracking ground antenna and hence are useful for the communication applications.

Archived from the original on Diffedence 7 launches of the GSLV have had worse results with 4 ending in gspv and only two successes; it also has one partial failure launch. The digital auto-pilot and closed loop guidance scheme ensure the required altitude maneuver and guide injection of the spacecraft to the specified orbit.

It will be used for the four Vikas engines first stage boosters on future missions. Comprehensive Orbital Launch Failure List”. The remote sensing satellites orbit splv earth from pole-to-pole at about 98 deg orbital-plane inclination.
