Resourcesat 3, 3A, 3B

The Indian Resourcesat-3 series of earth observation satellites is a data continuity mission of ISRO to the Resourcesat 2 and 2A.

Thes are medium resolution, wide swath satellites for advanced land and water resource management applications. Resourcesat- 3 and 3A would ensure continuity of data services required for the operational programmes in the areas of land and water resources management. It will carry Advanced Linear Imaging Scanning Sensor-3 (ALISS-3) payload consisting of VNIR and SWIR bands. Besides providing medium resolution wide-swath imagery, it is equipped with on-board atmospheric correction band to improve the data products. The ground sampling distances will be 20 m for VNIR and SWIR bands with the central EOM providing 10 m GSD. Hyperspectral atmospheric correction bands will operate in VNIR bands and have ground sampling distances of 240 m. Total field of view of the payload system is around 925 km at 795 km altitude orbit.

Resourcesat-3 carries the ALISS-III (Advanced LISS III) Imaging multi-spectral radiometer and the ATCOR (Atmospheric correction) High resolution optical imager
