- Launching vehicle- Polar Satellite Launch Vehicle (PSLV-C46)
- Launching station- Satish Dhawan Space Centre (SDSC) SHAR, Sriharikota in Andhra Pradesh
About:
- RISAT-2B is a Radar imaging earth observation satellite which is indigenously developed by Indian Space Research Organisation (ISRO)
- The satellite is placed in an inclined orbit, 37 degrees to the equator to increase the number of imaging angles and opportunities and is being operated in X band
Features:
- Effective for whole day operation during day/night/all weather conditions
- Allows high-resolution spot imaging of any location of interest
- It is a Synthetic Aperture Radar (SAR): SAR is a form of Radar that creates 2-dimensional 0r 3-dimensional imaging of objects, for example, landscape.
- RISAT-2B provides RADAR imaging modes of 1m x 0.5m resolution and 0.5m x 0.3m resolution that are very high resolutions.
- It has vast ranging applications including agriculture, disaster management, geosciences, forestry, crops, hydrology, and Cryosphere
Background:
- RISAT-2B is India's 3rd radar imaging satellite program after RISAT-2 launched in 2009 (before RISAT-1) and RISAT-1 launched in 2012
- RISAT-2 is the first radar observation satellite India has launched in 2012 designed to monitor India's borders
- RISAT-1 was second in series and focused on natural resources management only
