AIS (Universal shipborne Automatic Identification System) has been introduced, and AIS instruments are now widely installed onboard certain ships which are obliged by SOLAS. AIS target data should be provided to deck officers with relevant instruments that can be display them on chart, and they can use the data effectively for decision making of ship navigation. However, the navigation instruments like radar or ECDIS (Electronic Chart Display and Information System) which has such function of overlay display of target data on chart are so expensive and can be used in limited large scale vessels. So, we propose more inexpensive system which has similar functions about AIS target display. Moreover, AIS can output not only other ship's target data but also own ship's sailing data periodically with digital format i.e. NMEA format, and they are enough to achieve electronic navigation. In this paper, we show a simple design of navigation system using AIS data, and also show a prototype system on actual merchant vessel.
