ISRO on monday launched an all-wheather satellite to boost India's defence surveillance capabilities.
The satellite was sucessfully launched from ISRO's Satish Dhawan space centre, Sriharikota.
RISAT has all-weather capability to take images of the Earth and would also be beneficial in mapping and managing natural disasters, such as floods and landslides, besides amplifying defence surveillance capabilities of the nation.
It would also help keep track of ships at seat that could pose a threat. It uses Synthetic Aperture Radar (SAR), equipped with many antennas to receive signals that are processed into high-resolution pictures.
