Earth Observation Satilite

Indian Remote Sensing (IRS) satellite system was commissioned with the launch of IRS-1A, in 1988. With nine 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.


CARTOSAT - 2B is the seventeenth satellite in the Indian Remote Sensing Satellite series (IRS). CARTOSAT-2B carries a panchromatic camera (PAN) similar to those of its predecessors - CARTOSAT-2 and 2A. It is capable of imaging a swath (geographical strip) of 9.6 km with a resolution of better than 1 meter. The scene specific spot imagery sent by CARTOSAT-2B's PAN will be useful for cartographic and a host of other applications. The highly agile CARTOSAT-2B is steerable up to ± 26o along as well as across track to obtain stereoscopic imagery and achieve a four to five day revisit capability.
