The Automatic Identification System AIS is an autonomous and continuous broadcast system that exchanges maritime safetysecurity information between participating vessels and shore stations. In addition to providing a means for maritime administrations to effectively track the movement of vessels in coastal and inland waters, AIS can be a means to transmit information to ships in port or underway that contributes to safety-of-navigation and protection of the environment using Application Specific Messages ASMs. The United States Coast Guard Research and Development Center has developed processes to manage the ASMs. Several standard ASMs have been defined and methods have been developed for message creation, routing, queuing, transmission and monitoring. An AIS transmit architecture aligned with International standards has been developed to implement the efficient and robust transmission of ASMs. This report describes the architecture and various components of that architecture including an AIS router and ASM Manager to implement the queuing and prioritization algorithms. Results of testing AIS routers, base stations and the ASM Manager are presented along with recommendations for operational use. An integration plan of the proposed AIS Transmit architecture with the current Nationwide AIS architecture and the Ports and Waterways Security System is also presented along with interfaces to external agencies that provide maritime safety and security information. The agencies include National Oceanic and Atmospheric Administration, United States Army Corps of Engineers, National Marine Sanctuary, and the National Weather Service.
