Abstract
Maritime search and rescue (SAR) is hampered by difficulty in knowing that a vessel is in distress, identifying the vessel, determining its location, and directing a rescue unit to the scene. The United States Coast Guard has developed and is evaluating an electronic Distress Alerting and Locating System (DALS). Basically this system is comprised of a remote unit on the distressed vessel, which transmits an emergency call, identification, and geographic coordinates from Loran-C and Omega. This data is relayed through a shore mounted translator to a base station where a computer interprets the information and vectors a rescue craft to the scene. This thesis describes the nature of the SAR problem, evolution of the DALS, identification of the problems inherent in the system, and a systematic plan for implementation.
