IRS-1C was the fifth remote sensing Indian satellite built, and designed by Indian Space Research Organization (ISRO). IRS-1C is first second-generation operational Remote Sensing Satellite. The satellite carries payloads with enhanced capabilities like better spatial resolution additional spectral bands, improved repeatability and augment the remote sensing capability of the existing IRS-1A and IRS-1B.
Objective
The primary objective of IRS-1C was to provide systematic and repetitive acquisition of data of the Earth's surface under nearly constant illumination conditions.{{cite web|url=http://www.fcnym.unlp.edu.ar/catedras/geofoto/geo_html/informacion/pdf/Euroimage/irs.pdf|title=IRS-1C / 1D|publisher=National University of Argentina - Eurimage|access-date=13 May 2021|archive-date=7 February 2021|archive-url=https://web.archive.org/web/20210207183906/https://www.fcnym.unlp.edu.ar/catedras/geofoto/geo_html/informacion/pdf/Euroimage/irs.pdf|url-status=dead}}
Satellite
IRS-1C was the fifth of the Indian natural resource imaging satellites and was launched by a Molniya-M launch vehicle from the Baikonur Cosmodrome. The {{cvt|1250|kg}} satellite carried three instruments. Images from regions other than India will be downlinked and distributed through a commercial entity in the United States. IRS-1C used S-band for broadcasting and X-band for uplinking of data. The satellite was equipped with onboard tape recorder with storage capacity of 62 Gigabits.
Instruments
IRS-1C was equipped with three instruments:
- Linear Imaging Self-Scanning Sensor-3 (LISS-3) of {{cvt|23.5|m}} resolution in (VIS / NIR, {{cvt|70.5|m}} resolution in short-wave infrared (SWIR), for high-resolution land and vegetation observation
- Panchromatic Camera (PAN) of {{cvt|5.8|m}} resolution, for very-high-resolution land imagery
- Wide-Field Sensor (WiFS) of {{cvt|190|m}} resolution, for land and vegetation observation {{cite web|url=https://nssdc.gsfc.nasa.gov/nmc/spacecraft/display.action?id=1995-072A |title=Display: IRS-1C 1995-072|publisher=NASA|date=27 April 2021|access-date=13 May 2021}} {{PD-notice}}
Mission
The images was marketed through a private company in the United States. The data transmitted from the satellite was gathered from National Remote Sensing Centre, Hyderabad and EOSAT, a partnership of Hughes Aircraft and RCA.{{cite web|url=http://www.fas.org/spp/guide/india/earth/irs.htm|title=IRS (Indian Remote Sensing Programme)|publisher=Federation of American Scientists|access-date=March 8, 2013}}
IRS-1C completed its services on 21 September 2005 after serving for 10 years.{{cite web|url=https://www.wmo-sat.info/oscar/satellites/view/irs_1c|title=Satellite: IRS-1C|publisher=World Meteorological Organization|date=28 July 2015|access-date=13 May 2021}}
