DGPS Data
STATION: Shows GOOD or NG.
DATA: Shows GOOD or NG.
SIG. S: Signal Strength. A figure
between 0 and 99 is shown. The higher
the figure the stronger the beacon signal.
SNR: Signal to Noise Ratio. A figure
between 1and 22 is shown. A figure under
18 means position will be inaccurate.
When your boat is in the service area of a
beacon station, SNR should be 21 or 22.
If not, the problem may lie with the
grounding, radar interference or generator
noise on own boat.
