This paper describes the VMS (Vessel Management System) network infrastructure development, which is recently implemented for Taiwan Fisheries Administration (FA), Council of Agriculture Executive Yuan of Republic of China. The primary objective is to provide innovative solutions for FA monitoring the real-time fishing vessel’s position and efficient management of fisheries resource control. The concept of location diversity has been adopted for the VMS network design to enhance the radio link quality. The system network is configured to Internet gateway for in-land data transmission. In addition, we tested the operation frequency 4.16MHz of VMS system and then compared with by using the operation frequency 8.264MHz.We figure out the result of operation frequency 8.264MHz is better than the operation frequency 4.16MHz.
