COG/SOG Filter
The COG/SOG filter averages the velocity vectors to
compensate for the oscillating motion of the vessel,
giving a clearer indication of the vessel’s course and
speed.
The filter does not affect the calculation of your
receiver’s reported position. The velocity vectors
calculated from the signal provide an instantaneous
measure of speed and direction of the receiver. The
COG and SOG can therefor seem erratic under
certain conditions. For example, when a vessel is
moving slowly through rough seas, the receiver
moves from side to side as well as in the direction
of travel.
Slow moving vessels, or vessels sailing in rough
seas will benefit from a high setting, whereas a
power boat that can quickly change speed and
direction will benefit from a low setting.
Selecting COG/SOG filter
You can change the level of filter applied to
COG/SOG.
