NEW DELHI — India should have up to 100 satellites in orbit to safeguard Indian waters and counter Chinese surveillance in the region, a senior scientist says. As many as 19 Chinese surveillance satellites are currently monitoring the Indian Ocean region, one of the world’s most strategic areas, and India “needs to create capabilities to neutralize the information that is being transmitted through these satellites,” says Avinash Chander, director general of the Defense Research and Development Organization (DRDO).
