Payload capability had been progressively increased by more than 600 kg since the first PSLV launch. The launch of the first satellite in the Indian Regional Navigation Satellite System of the Indian Space Research Organization (ISRO), scheduled for 12 June from Sriharikota, has been postponed by 14 days after an anomaly was discovered just 11 days before launch. The standard version of the PSLV has four stages using solid and liquid propulsion systems alternately and six strap-on boosters. Roll control is provided by the fourth stage reaction control system (RCS). As of 16 December 2015[update] the PSLV has made 32 launches, with 30 successfully reaching their planned orbits, one outright failure and one partial failure. Even though the mission was a failure, the launch team and an expert committee appointed thereafter noted that the mission had validated many technologies and that most sub-systems had performed optimally. STRaND-1 The PSLV was first launched on 20 September 1993. NLS-5, a single satellite, flew out and finally the tenth satellite Rubin-8 went along with the fourth stage into orbit. [83][84], The launch was witnessed by the former Prime Minister I.K. ISRO has envisaged a number of variants of PSLV to cater to different mission requirements. The PSLV-CA, CA meaning "Core Alone", model premiered on 23 April 2007. Kent Ridge 1 It was developed to allow India to launch its Indian Remote Sensing (IRS) satellites into Sun synchronous orbits, a service that was, until the advent of the PSLV, commercially available only from Russia. The satellite IRNSS-1A, which would be the first in a series of seven navigation satellites was scheduled to be launched on board the Polar Satellite Launch Vehicle (PSLV) C22 at 1.01 am on 12 June. [99] The launch was attended by Prime minister Narendra Modi, the 15th Prime minister of India. Augmented Satellite Launch Vehicle (ASLV): Designed to augment payload capacity, the first launch test of ASLV was held in 1987, and three others followed in 1988, 1992 and 1994. I was nurtured by the great Indian scientists of ISRO. This was followed by the deployment of other five satellites, namely Kent Ridge-1, VELOX-C1, VELOX-II, Galassia and Athenoxat-1 in quick succession in the subsequent three minutes. [5] After this initial setback, the PSLV successfully completed its second mission in 1994. SwissCube-1 was the first Swiss satellite, and ITUpSAT1 was the first satellite to be constructed in Turkey. The vehicle crashed into the Bay of Bengal 700 seconds after take off. PSLV can also launch small size satellites into geostationary transfer orbit (GTO). The injection velocity was 140 m/s low, resulting in an orbit of 301x823 km instead of the planned 817 km circular SSO. [11], PSLV-XL is the uprated version of Polar Satellite Launch Vehicle in its standard configuration boosted by more powerful, stretched strap-on boosters. PSLV was designed and developed in the early 1990s at Vikram Sarabhai Space Centre near Thiruvananthapuram, Kerala. As a result, the fourth stage was shut down by a software override timer after burning 435 s, before reaching the target orbit or depleting propellant. The second stage employs the Vikas engine and carries 41.5 tonnes (40 tonnes till C-5 mission) of liquid propellant – unsymmetrical dimethylhydrazine (UDMH) as fuel and nitrogen tetroxide (N2O4) as oxidizer. The PSLV-CA uses no strap-on boosters. It has undergone several improvements with each subsequent version, especially those involving thrust, efficiency as well as weight. Read more about the launchers in this article for the IAS Exam preparation.. About 45 seconds later, it propelled IMS-1 into the orbit. It built and launched the Mars Orbiter Mission which made India the first country to get to Mars on its first try. Here are some interesting facts about ISRO's workhorse Polar Satellite Launch Vehicle, commonly known by its abbreviation PSLV. Weighing 320 tonnes at lift-off, the vehicle uses larger strap-on motors (PSOM-XL) to achieve higher payload capability. Coast phase attitude control is provided by RCS. "During the electrical checks of the launch vehicle, an anomaly was observed in one of the electro-hydraulic control actuators in the second stage. The first and second stages performed as expected, but an attitude control problem led to the collision of the second and third stages at separation, and the payload failed to reach orbit. The PSLV-XL uses larger boosters which carry 12 tonnes of propellant and produce 719 kN thrust. [13], ISRO is also considering the development of a three-stage version of the rocket without six strap-on boosters (with the second stage of the four-stage version removed) which will be capable of placing 500 kg to LEO.[11][14]. The payload capability for this variant is 1800 kg compared to 1600 kg for the other variants. In the standard PSLV, each booster carries nine tonnes of propellant and produces 510 kN thrust.
