PSLV is the trusted workhorse launch Vehicle of ISRO.  During 1993-2008 period, PSLV had fourteen launches of which thirteen were consecutively successful. PSLV has repeatedly proved its reliability and versatility by launching 32 spacecrafts (16 Indian and 16 for international customers) into a variety of orbits so far. It may be recalled that during its previous mission on October 22, 2008, PSLV had successfully launched Chandrayaan-1 spacecraft, which is now exploring the Moon from lunar orbit.In its standard configuration, the 44 m tall PSLV has a lift-off mass of 295 tonne. It is a four-stage launch vehicle with the first and the third stages as well as ...

PSLV-C11, chosen to launch Chandrayaan-1 spacecraft, was an updated version of ISRO's Polar Satellite Launch Vehicle standard configuration. Weighing 320 tonne at lift-off, the vehicle used larger strap-on motors (PSOM-XL) to achieve higher payload capability. PSLV is the trusted workhorse launch Vehicle of ISRO. During September 1993- April 2008 period, PSLV had twelve consecutively successful launches carrying satellites to Sun Synchronous, Low Earth and Geosynchronous Transfer Orbits. On October 22, 2008, its fourteenth flight launched Chandrayaan-1 spacecraft.     By mid 2008, PSLV had repeatedly proved its reliability and versatility by launching 29 satellites into a variety of orbits. Of these, ten remote sensing satellites of India, an Indian satellite for amateur radio communications, a recoverable Space Capsule (SRE-1) and fourteen satellites from abroad were put into polar Sun Synchronous Orbits (SSO) of 550-820 km heights. Besides, PSLV has launched two satelli...

  PSLV-C9 is the thirteenth flight of ISRO's Polar Satellite Launch Vehicle (PSLV) and the third flight of its 'Core Alone' version as well. In this flight, PSLV launched ten payloads - India's 690 kg CARTOSAT-2A and 83 kg Indian Mini Satellite (IMS-1) as well as eight nanosatellites from abroad together weighing about 50 kg into a 635 km high polar Sun Synchronous Orbit (SSO) inclined at an angle of 97.94 deg to the equator.   With much lighter payloads compared to the ones placed into orbit by its standard version, PSLV-C9 is configured without the six solid propellant strap-on motors of the first stage. The previous two launches of PSLV were also such 'Core Alone' versions. The Core Alone PSLV-C9 had a lift-off mass of 230 tonne.     PSLV has emerged as the workhorse launch vehicle of ISRO with eleven consecutively successful flights so far. Since its first successful launch in 1994, PSLV has launched eight Indian remote sensing satellites, HAMSAT - an amateu...

GSLV-F04 is the fifth flight of India's Geosynchronous Satellite launch Vehicle (GSLV), launched INSAT-4CR satellite, into a Geosynchronous Transfer Orbit (GTO) of 170 km perigee and 35,975 km apogee with an orbital inclination of 21.7 degree with respect to equator on September 2, 2007. Subsequently, the satellite was manoeuvred into geostationary orbit using its own propulsion system. The 49 m tall GSLV, with a lift-off mass of 415 tonne, is a three-stage vehicle with solid, liquid and cryogenic stages. The first stage of GSLV, one of the largest in the world, uses Hydroxyl Terminated Polybutadiene (HTPB) based propellant. The second stage and the four strap-on motors surrounding the first stage use liquid propellant 'Vikas' engine burning UH25 and Nitrogen Tetraoxide. The third stage is a cryogenic stage using liquid Hydrogen as fuel and liquid Oxygen as oxidiser. GSLV employs S-band telemetry and C-band transponders for enabling vehicle performance monitoring, tracking,...
