The AXYS AIS Port Sentinel™ is a self-contained and fully automated weather and water level station that can be deployed in key locations in a port or along its approaches to facilitate vessel traffic management operations. Typical sensor configurations provide wind speed, wind direction, current speed, current direction, and water level (tide).

A unique feature of the AXYS AIS Port Sentinel™ is its ability to transmit over AIS transponders. To address the need for improved international vessel traffic management, the International Marine Organization (IMO) has mandated the use of AIS transponders according to a schedule commencing July 2002. The AXYS AIS Port Sentinel™ system was designed to interface with all IMO approved AIS Class A transponders and to complement the available information with environmental data. This data can optionally be combined with data collected from AXYS environmental buoy systems to provide a complete picture of the wind, wave, and current regime as well as the water level of a port and its environs.
