GPS SOG/COG Filter
The SOG/COG 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 the GPS position.
oscillating motion of the vessel, giving a clearer indication of the vessel’s
course and speed. The filter does not affect the calculation of the GPS position.
The velocity vectors calculated from the GPS Signal give an instantaneous
measure of speed and direction of the GPS antenna. The COG and SOG can
therefore seem erratic under certain conditions. For example, when a vessel is
moving slowly through rough seas, the antenna moves from side to side as
well as in the direction of the vessel.

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.

Compass Set Up
This option is used to calibrate a Raymarine heading sensor such as the Rate
Gyro Compass. Controls are provided for Linearise Compass which detects
and corrects for heading errors caused by metal objects, and Align Heading
which matches the displayed heading to a known heading or transit.

Refer to the Handbook supplied with your heading sensor for more details.
Language
Select the language in which you wish information to be displayed. The
selected language will be used for screen text, labels, menus and options, but
will not affect the letters displayed by the context-sensitive cursor. The
language setting also affects the display format for lat/long position
information.

Simulator
The simulator allows you to operate your display without data from the
antenna and/or external data sources. The system set up simulator options
have the following functions:

have the following functions:
•
Data provides simulated numerical data, and a waypoint display.
•
Radar provides simulated radar picture, with example targets. The pic-
ture does not change if you change the range, although the range rings are
adjusted (see Chapter 3)
