The NC3I network links 51 Naval and Coast Guard stations, located along the coast and on island territories. The network provides these stations coastal surveillance information obtained from various sensors such as the coastal radar chain of the Indian Coast Guard and automatic tracking systems as well as electro-optical cameras. The network rides on dedicated terrestrial data circuits, as well as, satellite communication, which helps the stations in remote locations to be networked. The Information Management and Analysis Centre (IMAC), at Gurgaon, is the centre where data from various sensors and databases is aggregated, correlated and then disseminated to various stations for enhanced awareness.
