Resourcesat 2, 2A

Resourcesat 2 [ISRO]

The Indian Resourcesat-2 earth observation satellite is a data continuity mission of ISRO with improved spectral bands of the Resourcesat-1 (IRS-P6). Compared to Resourcesat-1, LISS-4 multispectral swath has been enhanced from 23 km to 70 km based on user needs. Suitable changes including miniaturisation in payload electronics have been incorporated in Resourcesat-2.

Resourcesat-2 has a three-tier imaging capability, with a unique combination of payloads consisting of three solid-state cameras, viz., a high resolution Linear Imaging Self Scanning Sensor - LISS-IV, a medium resolution Linear Imaging Self Scanning Sensor - LISS-III and an Advanced Wide Field Sensor (AWiFS).

Additionally, the satellite carries an AIS-receiver for exactEarth (COMDEV), which is known as exactView 2 (EV 2).

Resourcesat-2 was launched in April 2011.

Resourcesat-2A, a follow on mission to Resourcesat-2, is intended to provide continuity of data to the users. The configuration is similar to Resourcesat-2. It was successfully launched in December 2016.
