1. Indian Remote Sensing satellites (IRS)

2. IRS Indian Remote Sensing satellites (IRS) are a series of Earth Observation satellites, built, launched and maintained by Indian Space Research Organisation. The IRS series provides many remote sensing services to India.

3. Indian Remote Sensing (IRS) satellite system was commissioned with the launch of IRS1A, in 1988. With twelve satellites in operation, IRS is the largest civilian remote sensing satellite constellation in the world providing imageries in a variety of spatial resolutions, spectral bands and swaths. The data is used for several applications covering agriculture, water resources, urban development, mineral prospecting, environment, forestry, drought and flood forecasting, ocean resources and disaster management.

4. IRS-1A Launch Date: March 17, 1988 IRS-1A, the first of the series of indigenous state-of-art remote sensing satellites, was successfully launched into a polar sun synchronous orbit on March 17, 1988 from the Soviet Cosmodrome at Baikonur . IRS-1A carries two cameras, LISS-I and LISS-II with resolutions of 73 metres and 36.25 metres respectively with a swath width of about 140 km during each pass over the country.
