・ 

SBAS compatible
In addition to positioning via standard GPS, you can also access high precision positioning data via SBAS (WAAS / EGNOS). This sensor can be connected to the GTD-110/150 chart plotter, the CVG-80/200 plotter sounder or the K-Link System to enable precision DGPS navigation.
The increasingly precise positioning data will help you improve safety at sea and locate fishing spots.

・ 

18-channel reception
This sensor incorporates a parallel 18-channel receiver to enable fast, accurate positioning.
