IRS-1C was the fourth remote sensing Indian satellite built, and designed by Indian Space Research Organization.


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.[1]


IRS-1C was equipped with three sensors :

  • PANchromatic camera of 6-meter resolution.
  • Linear Imaging Self Scanner(LISS)-III (23.6 meter solution)
  • Wide Field Sensor(WiFS) with 189 meter resolution.[2]

The satellite was equipped with onboard tape recorder with storage capacity of 62 Gigabits.[3]

Data Processing[edit]

The data transmitted from the satellite was gathered from National Remote Sensing Centre, Hyderabad and EOSAT, a partnership of Hughes Aircraft and RCA.[4] IRS-1C used S-band for broadcasting and X-band for uplinking of data.

Mission Completion[edit]

IRS-1C completed its services on September 21, 2007 after serving for 11 years and 8 months.[5]
