Parallel 18-channel receiver capabilities and compatibility
with SBAS (WAAS / EGNOS)
| Features |
|
|
| ・ |
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. |
