The Department of Homeland Security (DHS) Science and Technology Directorate is improving the ability of the U.S. Coast Guard (USCG), U.S. Customs and Border Protection (CBP), and other DHS operational components to interdict small vessels by developing a Coastal Surveillance System
(CSS) with an open, Web-based architecture for rapid technology insertion and agile information sharing. The CSS integrates data feeds from existing local and regional sensors. An unclassified data fusion engine then analyzes the data and provides law enforcement agencies with real-time actionable information, including vessel tracking in-formation. The CSS also provides a secure, service-based framework that can integrate into existing user networks without requiring a re-design of hardware infrastructure.
