The SeaPos 300 series GPS navigation sensors features type approved instruments for use on-board SOLAS vessels. All sensors are designed for integration with other navigation equipment, and will as default be configured and operated from an ECDIS without the need for separate external displays. The sensors are tested and approved in accordance with international regulations, and have the Wheelmark certification.


The SeaPos 300 series features:

  • SeaPos 300 - an IALA beacon receiver
  • SeaPos 310 - a GPS receiver
  • SeaPos 320 - a DGPS receiver


The SeaPos 300 series of GPS navigation sensors is designed to be fully integrated with other navigation systems. This means that these models are per default delivered without external display for configuration and operation. All operation and functionality are handled from typically the ECDIS in an integrated bridge system. The SeaPos 300 sensors are 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.


SeaPos 300 - IALA beacon receiver

The SeaPos 300 is an IALA beacon receiver designed to receive RTCM corrections from an IALA beacon infrastructure. Recommended antenna: IALA - Seatex nr. G060-13.

SeaPos 310 - GPS receiver

The SeaPos 310 is an all-in-view 50-channel GPS L1 receiver. Recommended antenna: GPS 4 - Seatex nr. A101-01.

SeaPos 320 - DGPS receiver

The SeaPos 320 is a differential GPS receiver, utilising RTCM corrections distributed by IALA beacons for augmented position accuracy and integrity. Recommended antenna: IALA/GNSS - Seatex nr. G060-88.


The interface to other navigation systems is provided via network or serial interface (RS-422), in accordance with international standards.

Easy to install and maintain

The SeaPos 300 series 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 storage device 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.
