IRS-P2 was an Earth observation satellite launched under the National Natural Resources Management System (NNRMS) programme undertaken by Indian Space Research Organisation (ISRO). The objectives of the mission were to provide spaceborne capability to India in observing and managing natural resources and utilizing them in a productive manner. {{Clarify|date=May 2021|reason=What exactly does utilizing natural resources in a productive manner mean?}} The satellite carried imaging multi-spectral radiometers on board for radio sensing of the resources.
History
The satellite was designed, developed and tested in just one and a half years.{{cite web|url=http://www.highbeam.com/doc/1G1-18846105.html |archive-url=https://web.archive.org/web/20150924150036/http://www.highbeam.com/doc/1G1-18846105.html |url-status=dead |title=India's IRS family comes of age (Indian Remote Sensing satellites)|newspaper=Hindustan Times|archive-date=September 24, 2015|date=1 August 1996|access-date=13 May 2021}} IRS-P2 is one of the satellites in the Indian Remote Sensing Programme of Earth Observation satellites, assembled, launched and maintained by the Indian Space Research Organisation. The satellite was controlled by ISRO Telemetry Tracking and Command Network (ISTRAC) in Bangalore, Lucknow and Mauritius. The National Remote Sensing Agency (NRSC), Hyderabad received the first signal from IRS-P2, 98 minutes after the launch. The IRS-P2 was declared operational from 7 November 1994 after certain orbital manoeuvres and started its 3-year-long observation mission.{{cite web|url=http://spaceyuga.com/pslv-polar-satellite-launch-vehicle/|archive-url=https://web.archive.org/web/20120207035425/http://spaceyuga.com/pslv-polar-satellite-launch-vehicle/|url-status=usurped|title=PSLV launch vehicle|archive-date=7 February 2012|access-date=13 May 2021}}{{cite web|title=India (Launchers)|url=http://claudelafleur.qc.ca/Indians-launchers.html|publisher=Spacecraft Encyclopedia|access-date=13 May 2021}} The letter "P" indicates that the satellite was to be launched aboard a Polar Satellite Launch Vehicle (PSLV).{{cite web|url=https://earth.esa.int/web/guest/missions/3rd-party-missions/historical-missions/irs-p3|publisher=ESA Earth Online|title=IRS-P3|access-date=13 May 2021}}
