“…It should be relatively simple, therefore, for a receiver to predict the senderʹs approximate location at the next transmission. Predictive AIS has been described by a number of sources as a way to use historic AIS information to predict the path of other vessels (Hexeberg, Flåten, Eriksen, & Brekke, 2017;Last, Bahlke, Hering-Bertram, & Linsen, 2014;Mazzarella, Arguedas, & Vespe, 2015), and these methods are already used for research and practice for additional collision avoidance techniques and better understanding of traffic patterns. But if a station stores the position at just the last transmission, it can predict a range where the sender should be at the next transmission.…”
