Description
The AWiFS camera provides enhanced capabilities compared to the WiFS camera on-board IRS-1C/1D, in terms of spatial resolution (56 m Vs 188m), radiometric resolution (10 bits Vs 7 bits) and Spectral bands (4 Vs 2) with the additional feature of on-board detector calibration using LEDs. The spectral bands of AWiFS are same as LISS-III.

The AWiFS camera is realized in two electro-optic modules viz.,. AWiFS-A and AWiFS-B, each containing four band assemblies. A combined swath of 740 Km is realized by mounting the two modules on the Deck, with their optical axes tilted by 11.94 deg away from the + yaw axis in opposite direction. With this mounting, a side lap of 128 pixels i.e., about 7.2kKm, is available in the combined swath.
