IRS 1C [ISRO]
IRS 1C and 1D (Indian Remote Sensing Satellite) were the second version of the series of indigenous state-of-art remote sensing satellites.
These satellites carried payloads with enhanced capabilities like better spatial resolution additional spectral band, improved repetitivity and augment the remote sensing capability of the first generation IRS-1A and IRS-1B. The payload consisted of three solid state push broom cameras:
The first satellite, IRS 1C was launched on 28 December 1995 on a Russian Molniya-M (Blok-2BL) rocket. It operated until it was decomissioned on21 September 2007 after serving for 11 years and 8 months.
The second satellite, IRS 1D followed on 29 September 1997 on an indigenious PSLV-G (2) rocket, although the orbit was lower than intended. Its mission eas completed during January 2010 after serving for 12 years and 3 months.
