Resourcesat-2 is a follow on mission to Resourcesat-1 and the eighteenth Indian remote sensing satellite built by Indian Space Research Organisation (ISRO). The new satellite provides the same services as the original Resourcesat-1, but was also designed to "provide data with enhanced multispectral and spatial coverage".{{cite web |url=https://www.isro.gov.in/Spacecraft/resourcesat-2|title=RESOURCESAT-2|publisher=ISRO|date=2008|access-date=21 September 2015}} Compared to Resourcesat-1, LISS-4 multispectral swath has been enhanced from 23 km to 70 km based on user needs. Suitable changes including miniaturization in payload electronics have been incorporated in Resourcesat-2.
Launch
Resourcesat-2 along with YouthSat and X-Sat (Singapore) was launched by the Polar Satellite Launch Vehicle PSLV-C16 on 20 April 2011, at 04:42 UTC.{{cite web|url=https://economictimes.indiatimes.com/articleshow/8035732.cms|title=PSLV launch: PSLV-C16 a workhorse launch vehicle for India|newspaper=Economic Times|date=20 April 2011 |access-date=25 May 2013}}
Instruments
The satellite carries three electrooptical cameras on board:
- Advanced Wide-Field Sensor (AWiFS) with 56 meter spatial resolution
- The Linear Imaging Self-Scanning Sensor-3 (LISS-3) with 23.5 meter spatial resolution
- The Linear Imaging Self-Scanning Sensor-4 (LISS-4) with 5.8 meter spatial resolution {{cite web|url=http://www.isro.org/update/28-apr-2011/resourcesat-2-sends-high-quality-images|archive-url=https://web.archive.org/web/20150927084822/http://www.isro.org/update/28-apr-2011/resourcesat-2-sends-high-quality-images|url-status=dead|title=ResourceSat-2 Sends High Quality Images|publisher=ISRO|date=28 April 2011|archive-date=27 September 2015|access-date=14 May 2021}}
Additionally, the satellite carries an AIS-receiver for exactEarth (COMDEV), which is known as exactView 2 (EV 2).
Mission
The three cameras of ResourceSat-2, were switched on, on 28 April 2011, and the images of high quality were received at Shadnagar Earth Station of the National Remote Sensing Centre of ISRO.
