Viewing Information About AIS AIS alerts you to area traffic. When connected to an external AIS device, the chartplotter can show some AIS information about other vessels that are within range, that are equipped with a transponder, and that are actively transmitting AIS information. The information reported for each vessel includes the Maritime Mobile Service Identity (MMSI), the location, the GPS speed, the GPS heading, the time that has elapsed since the last position of the vessel was reported, the nearest approach, and the time to the nearest approach.

SART transmissions are different than standard AIS transmissions, so they look different than standard AIS symbols on the chartplotter. Instead of tracking a SART transmission for collision avoidance, you track a SART transmission to locate and assist a vessel. Navigating to a SART Transmission When you receive a SART transmission, a distress signal alarm appears. Select Review > Go To to begin navigation to the SART transmission.
