The Automatic Identification System (AIS) was initially designed for safety and security of navigation purposes. However it was progressively also used for other objectives, such as surveillance, and thus led to the discovery of behaviors such as the falsification of the AIS messages by people that have been carrying out illegal activities and will to keep their activities up in an hidden way. In...
This paper presents recent findings in maritime trajectory pattern and anomaly detection using long-term data collected via a shore-based network of Automatic Identification System (AIS). Since the establishment of the AIS network around Taiwan in 2009, the accumulated massive vessel trajectories have been extensively explored under a series of government research projects. The project themes include...
The implementation of pilotage task is inseparable from navigation information provided by shipborne navigation equipments. This paper presents a wearable pilotage system which adopts the PDA as the carrier for the electronic charts display as well as navigation information display and processing, through the Bluetooth wireless transmission to obtain the navigation information from shipborne AIS,...
AIS (automatic identification system), a new type of marine equipment, together with radar, are all the key navaid for a ship to navigate. Now in the seafaring, it is one of the most attentive research issues how to adequately and effectively use their information to improve the sail safety. The paper developed the integrated target information system based on ECDIS (electronic chart display and information...
AIS (Automatic Identification System), a new type of radio navaid system at sea, has more and more been used on a ship to identify a target and improve the navigation safety at sea. AIS network has also been constructed at the main harbor in many countries to enhance the traffic safety and the management at the harbor. In the paper, AIS system was briefly described. It was studied on AIS network frame...
One of the most important issue in maritime international transport is the necessity of increasing the level of safe in vesselpsilas navigation. We can achieve this goal using various methods. One of them is the enlargement and enrichment of navigational data processed by own deck computer net and external systems AIS (Automatic Identification System) and VTS (Vessel Traffic Service). The radar image...
Automatic identification system (AIS) is a system that enables ships to exchange information about ships and navigation, such as position, course, speed, name etc. automatically by VHF radio. The system is expected to contribute the improvement of marine traffic control and safety. In some congested waterways excessive transmission of AIS is a potential problem since the planning stage. In this study,...
