When the boat stops or moves very
slowly, the calculated GPS speed
and course become erratic. Static
navigation allows the erratic values to
be filtered:
0.01 to 9.99: If the boat speed
is slower than this, the speed is
shown as zero and the course stays
unchanged.
0 (Off): The calculated speed and
course are always used.
Waves and wind cause the boat
speed and course to fluctuate
slightly. To give stable readings, the
unit calculates these values by taking
several measurements and averaging
them.
A lower value averages
measurements over a shorter period
of time. This gives the most accurate
value but has the most fluctuations.
