Navigation Info
The Navigation Info view presents fundamental navigation data and aids the user in
navigating towards a waypoint and following a route. It presents information such as the
bearing and range to the next
waypoint, the ship’s current course over ground (COG) and
speed over ground (SOG) and current cross-track error (if sailing on a route).
Figure 34
– Navigation Info View
The left part of the Navigation Info view presents current navigation information. In Figure
Figure 34
– Navigation Info View, an example of the
Navigation Info view is shown.
The information shown of the left side of the view explained below:
NAV RL to WP21
This means that the next way
point in the current route is named “WP21” and we are currently
using the navigation algorithm “Rhumb Line” (RL) to calculate range and bearing to the
waypoint.
BRG
Bearing to the next waypoint.
COG
The ship’s course over ground relative true north.
Note: COG is based on track angle which requires that the ship is moving. Thus, COG data
is not displayed when the SOG value is below 0.3 knots.
RNG
Range to the next waypoint. The unit for range is configurable in the Units view, see section
10.1.12
SOG
The ship’s speed over ground. The unit for SOG is configurable in the
Units view, see section
10.1.12
TTW
Time To Waypoint
– The estimated time left to next waypoint.
