Resourcesat 3S, 3SA

The Indian Resourcesat-3S series of earth observation satellites is a supplementary series to the Resourcesat 3 series.

These are missions for stereographic mapping with improved resolution in Panchromatic and Multispectral bands and along track stereo images for generating improved Digital Elevation Models (DEM) target of 5 m for the Area of Interest (AOI). Resourcesat-3S and 3SA satellites are with capabilities to provide along track high resolution panchromatic stereo and multi-spectral imagery. It carries two panchromatic camera PAN (fore) and PAN (aft) with 1.25 m resolution providing a swath of 60 km in PAN Band, and a Multispectral camera having bands in VNIR region with 2.5 m resolution providing a swath of 60 km.

Resourcesat-3S carries the LISS-V high resolution optical imager and the APAN panchromatic high resolution optical imager
