PSLV-C36 Successfully Launches Resourcesat-2a Remote Sensing Satellite
Dec 08, 2016

In Its 38th Flight (Pslv-C36), Isro's Polar Satellite Launch Vehicle Successfully Launched The 1,235 Kg Resourcesat-2a Satellite On December 7 From The Satish Dhawan Space Centre Shar, Sriharikota. 

  • Resourcesat-2a Is A Follow-On Mission To Resourcesat-1 And Resourcesat-2, Which Were Launched In 2003 And 2012 Respectively.

Remote sensing is the science of acquiring and analyzing information about objects or phenomena from a distance. Remote sensing means your acquiring information from a distance.

Key Highlights

  • This is the 37th consecutively successful mission of PSLV. 
  • After PSLV-C36 lift-off at 10:25 am from the first launch pad with the ignition of the first stage, the subsequent important flight events, namely, strap-on ignitions and separations, first stage separation, second stage ignition, payload fairing separation, second stage separation, third stage ignition and separation, fourth stage ignition and cut-off, took place as planned. 
  • After a flight of 17 minutes 5 seconds, the vehicle achieved a polar sun synchronous orbit of 824 km height inclined at an angle of 98.725 degree to the equator (very close to the intended orbit) and 47 seconds later, Resourcesat-2A was separated from the PSLV fourth stage. 
  • After separation, the two solar arrays of Resourcesat-2A deployed automatically and ISRO's telemetry, tracking and command network (ISTRAC) at Bangalore took over the control of the satellite. 
  • In the coming days, the satellite will be brought to its final operational configuration following which it will begin to provide imagery from its three cameras. The data sent by Resourcesat-2A will be useful for agricultural applications like crop area and crop production estimation, drought monitoring, soil mapping, cropping system analysis and farm advisories generation. 
  • Like its predecessors Resourcesat-1 and 2, Resourcesat-2A has a unique 3-tier imaging system with Advanced Wide Field Sensor (AWiFS), Linear Imaging Self Scanner-3 (LISS-3) and Linear Imaging Self Scanner-4 (LISS-4) cameras.
  • The AWiFS (Advanced Wide Field Sensor) provides images of 56-metre resolution that would be useful at the State level. 
  • The LISS-3 (Linear Imaging Self-scanning Sensor) of 23.5-metre resolution can take pictures at the district level; and the LISS-4 of 5.6 metre can provide taluk level information.
  • The Resourcesat-2A weighing 1,235 kg was injected into an 817 kilometer polar Sun Synchronous Orbit at around 20 minutes into the destination.
  • The ISRO put a few specialties into the mission. The new on-board cameras put for the first time on the launcher showed us the separation of the stages during the flight and the deployment of the solar panels of the satellite.
  • Resourcesat-1 was put in space in October 2003 and Resourcesat-2 in April 2011, each with a planned life of five years.

With this launch, the PSLV has yet again demonstrated its reliability. The total number of satellites launched by India’s workhorse launch vehicle PSLV including Resourcesat-2A has now reached 122, of which 43 are Indian and the remaining 79 are from abroad.


  • PSLV is the ISRO's versatile launch vehicle for launching multiple satellites in polar SSOs, Low Earth Orbits (LEO) as well as Geosynchronous Transfer Orbit (GTO) and sub GTO. 
  • With 36 successful launches, PSLV has emerged as the workhorse launch vehicle of ISRO and is offered for launching satellites for international customers. 
  • During 1994-2016 period, PSLV has launched a total of 121 satellites, of which 79 satellites are from abroad and 42 are Indian satellites.
  • The PSLV rocket is a four stage engine rocket powered by solid and liquid fuel alternatively.
