RESOURCESAT-2

RESOURCESAT-2 is a follow on mission to RESOURCESAT-1. It is intended to continue the remote sensing data services to global users provided by RESOURCESAT-1, and to provide data with enhanced spatial coverage, by enhancing the LISS-4 multispectral swath from 23 km to 70 km. 

RESOURCESAT-2 also carried an additional payload known as AIS (Automatic Identification System) from COMDEV, Canada as an experimental payload for ship surveillance in VHF band to derive position, speed and other information about ships.

RESOURCESAT-2 carries two Solid State Recorders with a capacity of 200 Giga Bytes each to store the images taken by its cameras which can be read out later to ground stations.

The major objectives of Resourcesat-2:

1. Provide continued remote sensing data services on an operational basis for integrated land and water resource management at a micro level with enhanced multispectral/ spatial coverage and stereo imaging.

2. Carryout studies in advanced areas of user applications to take full advantages of increased spatial and spectral resolution.
