- The document discusses several satellite sensors and their characteristics including Sentinel-2A MSI, IRS-P6 AWiFS, IRS-P6 LISS-III, IRS-P6 LISS-IV Mono, IRS-P6 LISS-IV MX, Landsat-1 RBV, and WorldView-3 CAVIS. - It provides information on the spatial resolution, number of bands, swath width, and archive period for some of the sensors. - Additional details are given on technologies like MSI and how sensors like AWiFS and LISS-III are designed and operate.

MSI covers 13 spectral bands (443–2190 nm), with a swath width of 290 km and a spatial resolution
of 10 m (four visible and near-infrared bands), 20 m (six red edge and shortwave infrared bands) and
60 m (three atmospheric correction bands).

* Cameras with special gratings & sensors can be used for MSI

14. AWiFS sensor is an improved version compared to the WiFS sensor flown inIRS-1C/1D.
AWiFS operates in four spectral bands identical to LISS-III, with a spatial resolution of 56 m. and
covering a swath of 740 kms. To cover such a wide swath, the AWiFS camera is split into two separate
electro-optic modules, AWiFS-A and AWiFS-B which are tilted by 11.94 degrees with respect to each
other.
IRS-P6 AWiFS

15. The LISS-III sensor is identical to the LISS-III flown in IRS-1C/1D spacecrafts except that the spatial
resolution of SWIR band (B5) has been improved to 23.5 m
LISS-III Camera

16. LISS-IV Camera
LISS-IV is a high resolution multi-spectral sensor operating in three spectral bands. LISS-IV provides a ground
resolution of 5.8 m and can be operated in either of two modes:. In Mono mode the full swath of 70 km will be
covered in any one single band which is selectable by ground command.

17. In Multispectral mode (Mx) LISS-IV covers a swath of 23 km. The user has to specify his area of
interest in terms of latitude/longitude. The LISS-IV can be tilted up to 26 degrees. In the across the
track direction thereby providing a revisit period of five days.
