The Integrated Coastal Surveillance System (ICSS) is a coastal surveillance system operated by India with the goal to protect its coastline, ensure regional security, and assist friendly navies by quickly detecting, locating and monitoring maritime activity in the Indian Ocean. The system was developed by the Defence Research and Development Organisation (DRDO) and Bharat Electronics, and forms part of the (NC3I). Although the ICSS was built primarily for coastal and maritime security, the system can also be used for vessel traffic management, harbour surveillance and navigation. The core of the ICSS is a network of remote ground-based radar stations called the Coastal Surveillance Network (CSN). In addition to radars, stations are also fitted with optical sensors, electro-optical sensors
