IRS-1A was the first remote sensing mission undertaken by the Indian Space Research Organization (ISRO). It was a part-operational, part-experimental mission to develop Indian expertise in satellite imagery.


IRS-1A was the first remote sensing mission undertaken by ISRO to provide imagery for various land-based applications. The mission's long-term objective was to develop indigenous remote sensing capability.[1]


IRS-1A carried two 'Linear Imaging Self-Scanning System' cameras, LISS-I and LISS-II, with a spatial resolution of 72.5 metres (238 ft) and 36 m respectively.[2]

Mission result[edit]

IRS-1A successfully completed its mission in July 1996 after operating for 8 years, 4 months.
