Indian Space Research Organisation launched PSLVC46 from Satish Dhawan Space Centre at Sriharikota at 5.30am. The special radar-enabled satellite has been placed at low earth orbit to detect hostile installations and monitor agriculture, forestry and possible disaster zones.
ISRO Chairman K Sivan had earlier described the mission as a “very, very important” one for the country.
With a mission life of five years, the satellite would also be used for military surveillance, ISRO sources said. The RISAT-2 has been actively used by India to monitor activities in camps across the border in Pakistan to thwart infiltration bids by terrorists.
