events and react accordingly:
• An alarm appears on AIS SART Target activation, regardless other AIS Alarm settings
• SART icon is red cross in red circle, very different from other ship icons
• SART targets are always displayed on top of AIS Report window, highlighted with orange color
• SART targets have Go To feature enabled
• Once activated, Go To SART function follows SART event position, even if its position changes
