<h2 id="objective">Objective</h2> <p>The primary objective of IRS-1C was to provide systematic and repetitive acquisition of data of the <a href="/facts/Earth/HLLmDfj0">Earth</a>'s surface under nearly constant illumination conditions.<a class="footnote-ref" id="fnref:1" href="#fn:1"><sup>1</sup></a> </p> <h2 id="satellite">Satellite</h2> <p>IRS-1C was the fifth of the Indian natural resource imaging satellites and was launched by a <a href="/facts/Molniya-M/Wu5tFKAt">Molniya-M</a> <a href="/facts/Launch_vehicle/g1GCGFJB">launch vehicle</a> from the <a href="/facts/Baikonur_Cosmodrome/sk16LwcH">Baikonur Cosmodrome</a>. The 1,250 kg (2,760 lb) satellite carried three instruments. Images from regions other than <a href="/facts/India/1kKHcnxM">India</a> will be downlinked and distributed through a commercial entity in the <a href="/facts/United_States/P0sCdLe5">United States</a>. IRS-1C used <a href="/facts/S_band/MF3nveB7">S-band</a> for broadcasting and <a href="/facts/X_band/eMpD5T2r">X-band</a> for uplinking of data. The satellite was equipped with onboard tape recorder with storage capacity of 62 <a href="/facts/Gigabit/X71SBDuf">Gigabits</a>. </p> <h2 id="instruments">Instruments</h2> <p>IRS-1C was equipped with three instruments: </p> <ul><li>Linear Imaging Self-Scanning Sensor-3 (LISS-3) of 23.5 m (77 ft) resolution in (<a href="/facts/Visible_spectrum/frPBh8o5">VIS</a> / <a href="/facts/Infrared/44XdJNcc">NIR</a>, 70.5 m (231 ft) resolution in <a href="/facts/Infrared/44XdJNcc">short-wave infrared</a> (SWIR), for high-resolution land and vegetation observation</li> <li>Panchromatic Camera (PAN) of 5.8 m (19 ft) resolution, for very-high-resolution land imagery</li> <li>Wide-Field Sensor (WiFS) of 190 m (620 ft) resolution, for land and vegetation observation <a class="footnote-ref" id="fnref:2" href="#fn:2"><sup>2</sup></a></li></ul> <h2 id="mission">Mission</h2> <p>The images was marketed through a private company in the <a href="/facts/United_States/P0sCdLe5">United States</a>.<a class="footnote-ref" id="fnref:3" href="#fn:3"><sup>3</sup></a> The data transmitted from the satellite was gathered from <a href="/facts/National_Remote_Sensing_Centre/aPTvpuky">National Remote Sensing Centre</a>, <a href="/facts/Hyderabad/APPUtNqU">Hyderabad</a> and <a href="/facts/Earth_observation_satellite/WK2zGRSV">EOSAT</a>, a partnership of <a href="/facts/Hughes_Aircraft_Company/NURPFI17">Hughes Aircraft</a> and <a href="/facts/RCA/NWyjNN6R">RCA</a>.<a class="footnote-ref" id="fnref:4" href="#fn:4"><sup>4</sup></a> </p><p>IRS-1C completed its services on 21 September 2005 after serving for 10 years.<a class="footnote-ref" id="fnref:5" href="#fn:5"><sup>5</sup></a> </p> <h2 id="see-also">See also</h2> <ul> <li>Spaceflight portal</li></ul> <ul><li><a href="/facts/Indian_Remote_Sensing/pdGcNGg5">Indian Remote Sensing</a></li></ul> <h2 id="external-links">External links</h2> <ul><li><a href="https://web.archive.org/web/20101125200120/http://isro.org/satellites/irs-1c.aspx">ISRO IRS-1C link</a></li></ul> <h2 id="references">References</h2> <ol> <li id="fn:1"><p>"IRS-1C / 1D" (PDF).
