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.

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.

Select the SOG/COG filter setting as required. This can be set to HIGH,

MEDIUM or LOW.

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:

•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).

•Both provides simulated data and radar picture.

When the simulator is switched on, a SIMULATOR data box is displayed during operation, showing the simulation selected.
