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 metre. 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 ± 26^o along as well as across track to obtain stereoscopic imagery and achieve a four to five day revisit capability.
