ISRO successfully launched radar imaging satellite RISAT-2B on-board PSLV-C46 from Sriharikota.
- RISAT-2B was placed into an orbit of 555 km with an inclination of 37 degree to the equator.
- This is the fourth flight unit of the RISAT programme and it would be used for reconnaissance, strategic surveillance and disaster management.
- The satellite has a mass of 615 kg and feature an X-band SAR (Synthetic Aperture Radar).
- It is built for a 5 year operational lifetime.
- RISAT 2B will be launched into a 37° inclined orbit at 555 km orbital height.
- RISAT 2B, RISAT 2BR1 and RISAT 2BR2 will be launched in 2019 on Indian PSLV launch vehicles.
- In India radar imaging are used for crop estimation because our main crop growing season of kharif is in May-September when it rains and gets cloudy.
- We have used this data extensively for forestry, soil, land use, geology and during floods and cyclone.
- Due to an all-weather seeing feature, the satellite becomes special for security forces and disaster relief agencies.
