 PSLV-C19   India's first indigenously built all-weather Radar Imaging Satellite, RISAT-1, with applications ranging from agriculture to natural disaster management, is now in polar  orbit after its carrier, the PSLV-C19, was launched with clinical precision from the Sriharikota spaceport of the Indian Space Research Organisation (ISRO) on Thursday. RISAT-1, weighing 1,858 kg and the heaviest satellite launched yet by the PSLV, is a state-of-the-art Active Microwave Remote Sensing Satellite carrying a Synthetic Aperture Radar (SAR) that will operate in the C-band. In simpler terms, the RISAT-1 can beam back imaging of the earth surface features at day and night and under all imagined weather conditions. SAR, which gives the RISAT-1 its magical roving eyes, also makes it superior to the generation of optical remote sensing satellites in clearer imaging at all times and under any condition. Terming the PSLV-C19 launch a “grand success,” ISRO Chairman K. Radhak
