4.6 Navigation Application
The Navigation Application uses data from the external GPS Float, and the internal
compass to provide navigation information to the diver.
Before a dive commences, the Artemis Manager PC software should be used to create a
Mission File that is uploaded onto Artemis via the USB cable, and then selected as the
current mission file to use from the Settings Application.
The Mission File defines a series of “Markers” that have their geographical locations
shown on the display. Marker locations may be entered in the Artemis Manager
software or imported from third-party software (such as Google Earth TM™ KML data).
For flexibility, the Diver and Supervisor may pre-agree on the styles and colours of
markers to be used and what they represent.
The Navigation display shows a scalable chart of the diver’s position and mission
markers. The charts grid spacing is shown at the top left of the display, and currently
selected marker name at the top right.
The two large numbers at the bottom of the display are calculated from the current
GPS position and show the divers distance and course-to-swim to the selected marker.
The magnetic compass heading and Navigation Bubble are shown in the Status Bar at
the bottom of the display (see section 4.2.7 for more information).
For further information on creating Mission Files, please refer to the Artemis Manager
“Mission File Editor” section on page 35.
When the Navigation Application is active, the console buttons have the following
functions…
Mark Target
Pressing this key will add a “Diver Marker” to the mission file at the divers’
current location.
In total the Mission File can support 20 markers, but must contain spare
capacity to allow the marker to be added.
Next Target
Pressing this key will sequentially cycle through the list of defined markers,
selecting each one in turn as the current navigation destination.
Zoom
This key cycles through a list of chart scales, from “Show All”, progressively
zooming into the display.
Display Mode
This key selects whether the display is shown in Cartesian “North Up” or
Polar “Diver Heading Up” modes.
