ASM is one of the study to provide a variety of maritime safety information as well as ship’s position and navigational information that are their own function since 2004. However, it was reported that the increased use of ASM message on the existing AIS channel affects the part of the existing AIS own function such as the transmission of the ship’s position and safe related information. Also seamless MSP service is difficult on the low transmission rate of the existing AIS channel. This study aims to reduce the marine officer’s workload through automating captain’s mandatory reporting items using the one of the next maritime digital communication technology. For this purpose, we designed and experimented of the new ASM protocol through analyzing a domestic regulation about passenger flight and ASM message.
