| Summary | Taiwan is located in the central of Western Pacific first island chain as well as the marine transport hub in Northeast Asia. Because the superior geographical location promotes the marine activities on the surrounding waters frequently. Therefore, sailing ship density and maritime traffic are classified as high class. Above all, in order to grasp the dynamic information of the sailing ships under the jurisdiction of Taiwan effectively, this project carries out two-stage research on transmission and receiving of the Automatic Identification System (AIS). The first stage improves the performance of the AIS receiving antenna, including the design of the antenna, plans of the receiving angle and base station site to promote AIS antenna effective distance. The second stage is to extend the communication coverage of AIS in the form of mobile relay transmission technology through deploying the AIS relay station on navigational ships and developing the receiving and decoding method of the AIS mobile relay transmission technology. The AIS information is transmitted back to the coast station by RF so as to have receiving and forwarding function, thus extending the monitoring distance of AIS to build a wider communication coverage. Through this project, we hope to achieve effective monitoring of ship navigation information, and more clearly and comprehensively grasp the situation of the navigation environment in the sea area around Taiwan, thus enhancing navigation safety. |
