Although sealing the entire border would be a significant challenge mainly due to variations in the terrain and topography, the use of remote sensing systems provides one of the more effective means to overcome it. Attempts at infiltration could be detected by using low earth orbit surveillance satellites, which would in turn enable the blocking of infiltrators through suitable force deployment. In this regard, the active deployment of Medium Altitude Long Endurance (MALE) Unmanned Aerial Vehicles (UAVs) which were reportedly used in Operation Ginger in 2011, and High Altitude Long Endurance (HALE) UAVs that are currently under consideration for procurement, will improve India’s surveillance and reconnaissance capabilities. Further, the deployment of high-resolution radar based imaging sensors with all-weather day and night observation capability in the form of the Synthetic Aperture Radar system (SAR sensor platform) would also be advantageous in both the surveillance and active reconnaissance roles. In the aftermath of the November 2008 terror attacks in Mumbai, India had benefited from cooperation with Israel in developing RISAT 2 and especially its SAR system. Today, the RISAT 1 and 2 are the only two declared SAR systems in India’s possession for all weather day and night capability. In addition, the CARTOSAT is also available for imaging purposes. In fact, ISRO has acknowledged that CARTOSAT was used for imaging areas where surgical strikes were carried out. India would need more than one satellite constellation. It would require multiple satellites that repeat their observation of a target area; ideally one after the other in a contiguous form so that one satellite is always present over the AoI – Area of Interest . To meet that objective, preferably smaller satellite systems at very low earth orbit to enable short revisits and repeat cycles would be ideal. It is highly recommended that a range of nano and pico satellites be manufactured and their employment integrated with the border management system.
