如今，船舶自动报告系统(AIS--自动识别系统、LRIT--远程识别和跟踪、VMS--船舶监控系统)可以实现对船舶的全球跟踪。显示结果的一种方式是在感兴趣区域的当前船只位置地图中显示，即海上态势图片(MSP)。MSP是动态的，必须通过融合报告系统的消息、构建船舶轨迹和预测船舶位置来创建，以校正延迟，特别是在卫星接收到AIS的情况下，卫星接收到的AIS构成了大部分数据。本文讨论了结果MSP的完备性及其位置的准确性，量化了各个数据源的附加值。
Automatic ship reporting systems (AIS – Automatic identification System, LRIT – Long Range Identification and Tracking, VMS – Vessel Monitoring System) today allow global tracking of ships. One way to display the results is in a map of current ship positions over an area of interest, the Maritime Situational Picture (MSP). The MSP is dynamic and must be created by fusing the reporting systems' messages, constructing ship tracks and predicting ship positions to correct for latency especially in the case of AIS received by satellite which forms the bulk of the data. This paper discusses the completeness of the resulting MSP and the accuracy of its positions, quantifying the additional value of the individual data sources.
