NOTE

Due to the cartography contained in the C-MAP NT+ C-CARD there will be multiple charts shown within the same scale range.

Measure DST & BRG: allows measuring the Distance and Bearing between two points.

Ship Icon: select the preferred icon (among 5 choices) to display ship on the Chart page.

Cursor Speed: select the preferred speed among Low, Medium and High for the cursor in the Chart page and in the menu page.

Units of Measure: allows customization of Disatnce, Speed, Depth and Altitude.

3.15.4.4 Fix

Fix Correction: Enables / Disables the correction of the received fix position.

Compute Correction: Corrects fixes from the positioning instrument. By placing the cursor on the ship's real position and selecting this option, the error is calculated and internally memorized for appropriate correction, but not applied.

Correction Offset: Allows entering the correction to the received fix position.

Position Filter: Attenuate the fix position error.

Speed Filter: Attenuate the fix position error.

3.15.4.5 Navigate

Map Datum: Allows selecting any datum reference from the ones available on the chart plotter. The chart plotter allows selecting about 100 different datum. The default Map Datum is WGS84. C-MAP charts are saved in WGS84 datum. The Map Datum selection switches to the selected reference datum applying the datum offsets stored with the charts.

Map Orientation

-North Up: The top of the map is fixed to North.

-Course Up: The top of the map is oriented to the current Course value.

-Track Up: The top of the map is oriented to the current Navigation Leg. Map Orientation Resolution: 5 – 30 degrees defines the maximum variation of

the reference angle after which the map changes its orientation.

Coordinate System

-Ddd mm.mm: Degrees minutes and hundreds of minutes.

-Ddd mm.mmm: Degrees minutes and thousands of minutes.

-Ddd mm.sss: Degrees minutes and seconds.

-TD: TD function allows converting GPS coordinates to Loran-C coordinates and vice versa. Any position can be displayed or entered in TDs. The chart plotter allows choosing one of the (about) 30 Loran-C chains and allows selecting the two TD stations (Slave 1 and Slave 2). A correction to the TD values can be applied by entering the correction offset (ASF1 and ASF2) to the slaves. (ASF=Additional Secondary phase Factor )

-Select Loran Chain

-Select Slave1
