Kongsberg AIS 300




The AIS 300 is our 4th generation AIS class A mobile station designed to be fully integrated in a ship’s bridge environment. An improved receiver sensitivity of -115 dBm gives an increased range compared to AIS units with the standard sensitivity of -107 dBm. The AIS 300 is tested and approved in accordance with international regulations and have the Wheelmark certification.


IMO requirement

In accordance with IMO requirements all SOLAS ships in international traffic above 300 gross tons must have an Automatic Identification Systems (AIS) installed onboard. Our AIS system (AIS mobile stations) is in accordance with the IMO regulations.


The AIS 300 is designed to be fully integrated with other navigation systems. This means that it is default delivered without an external display (MKD – Minimum Keyboard and Display). All operations and functionalities are handled from the ECDIS in an integrated bridge system. The AIS 300 is hence type approved with ECDIS from different manufacturers and brands, in order to avoid installing a redundant display/keyboard. One important principle of e-navigation is to reduce the number of displays on the bridge. The navigator needs to have important information easily available in order to reduce response time for decisions. Better integration will lead to a better bridge environment as well as a simpler installation. If the AIS Unit is not to be fully integrated, an external display is needed in order to operate the system.

ECDIS / ECS, radar and sensor interface

Interface to ECDIS / ECS and radar is provided via the Presentation Interface (PI) available on network or serial interface (RS-422). It is implicit that the system supports the AIS interface. When interfacing the AIS to radar and chart systems, AIS target information such as position, heading course and speed become easily available to the mariner.

Easy to install and maintain

The AIS 300 is by default delivered with a bracket containing a solution for strain relief in both ends. The unit is easily configured via a built-in WEB user interface (UI). Software updates are supported via the WEB UI but also the USB interface will automatically detect new software when a USB stick is inserted. The update will be accomplished without interfering with the existing configuration. The latest software will continuously be available for download from an FTP server hosted by KONGSBERG.
