Abstract

This research and development paper gives the information about AIS protocol, its applications and implementation of the protocol in Field Programmable Gate Array (FPGA). Automatic Identification System (AIS) protocol is a scheme for generating a self-organized data network between marine vessels. AIS can be used for Collision avoidance, Search & rescue, Fishing Fleet Monitoring and Control, Vessel traffic services and aids to navigation. AIS Transponder on ship broadcast information regarding its speed, position and navigational status at regular interval using VHF transponder at 161.975 MHz and 162.025 MHz’s These speed, position and direction information is generated from the ship's navigational sensors, navigation satellite system (GNSS) receiver and gyrocompass. Other information like name of the vessel and VHF call sign is programmed when installing the equipment and it is also transmitted at regular intervals. This research paper proposes a technique for implementation of AIS protocol in FPGA. In this paper FPGA is used for processing the data because this technology gives flexible designs with relatively short design time and at the same time maintain some of the good properties of ASICs, such as relatively high performance and low power consumption.
