Key highlights about the satellite
- RISAT-2B is an indigenously developed Synthetic Aperture Radar (SAR) Imaging Satellite operating in the X-band.
- It was launched by PSLV-C46
- RISAT-2B is a radar imaging earth observation satellite weighing about 615 kg.
- Can operate in different modes: The highly agile satellite is capable of operating in different modes including Very High Resolution RADAR imaging modes of 1m x 0.5m resolution and 0.5m x 0.3m resolution
- In order to increase the number of imaging opportunities, the satellite is placed in an inclined orbit
- Can be operated in all time: As, RISAT-2B is a Radar Imaging satellite; it can be operated effectively during day / night / all weather conditions
- Control of the satellite: ISRO Telemetry Tracking and Command Network (ISTRAC) at Bengaluru assumed control of the satellite.
- RISAT-2B is an advanced Earth Observation satellite with an advanced technology of 3.6m radial rib antenna
- The Satellite will be used for high resolution spot imaging of locations of interest.
- Apart from this, data from RISAT-2B will also be utilized for agriculture applications and disaster management support.
- Applications of X-Band SAR imagery include Hydrology, Crops, Forestry, Geosciences and Cryosphere.
- During the time of exigencies, very high resolution, day/night/all-weather imaging capabilities of RISAT-2B could be utilized for Disaster Management Support
