Overview

An Entry Event is generated when an AIS-transmitting vessel enters a defined Area of Interest (AOI). These events will start generating from the time of configuration (it is not possible to generate historical data retroactively).

Why Use This? 

• To monitor all (AIS) vessels entering into a restricted zone, like a Marine Protected Area
• To monitor all (AIS) vessels entering a known suspicious area
• To monitor all (AIS) vessels entering into a port

Not a good use case for 

• Monitoring all (AIS) vessels into relatively large areas, like Exclusive Economic Zones (EEZs)
  • AOIs must be <1,000,000 sq km to be able to configure Entry Events
• Viewing all vessels in an area in real-time
  • Entry Events only capture the moment a vessel has entered an area. It is not meant for continuing to track vessels in an area, especially if they continuously operate in that area. 
  • For this use case, consider using Show Nearby Tracks instead. 

Event Details

Standard information

Vessel information - name, MMSI, Type based on AIS data, IMO, Length based on AIS data

Date and time of the event

Location (lat/lon)

Event history - number of times Skylight has detected this behavior from this vessel

Additional information

Duration - How long the vessel has been/was in the Area (up to 72 hours)

Exit - The time of a vessel’s exit from the Area of interest (when less than 72 hours)

Area - The name of the relevant Area of Interest

Latency

Entry events are computed in real time and may be available in just a few minutes depending on AIS signal. 

Average latency is 1 hour.
