Abstract – AIS (Automatic Identification System) are recognized to be useful equipment for navigator because it is able to get much information such as ship’s name, destination port, etc. which are not able to be got by ordinary nautical instruments. However some users sent false information by wrong operation and in the previous study, it became clear that several problems were occurred by operation mistake. Four years passed since last questionnaire survey, the environment surrounding AIS changed significantly. For example, it was changed to input by three letter code that the destination port in JAPAN. Therefore we carried out questionnaire survey for navigator to investigate the intelligibility and the utilization, and we researched the problems between four years ago research and present one. Some representative knowledge will be shown below.
　(1) The ships are sending correct information because of the publicity work and the instruction of JCG (Japan Coast Guard).
　(2) The reliability of the AIS information is decreased for navigator in spite of the sending information definitely.
　(3) The problem occurs in the operation system, for example time zone is not unified.
　(4) The navigator has dissatisfaction toward the code indication system for the destination port.
　(5) The new systems are built for ship’s operation control and/or search and rescue to collect AIS information via satellite, but someone says that a several risk will be included in that system.
