4.4.2 Mission Selection
The Mission setting allows the diver to cycle through a list of available “.mission” files
on the Artemis storage. These files are created using the “Artemis Manager” software
(see section 5.5) and copied onto Artemis’ internal storage via the USB lead (see
section 3.10).
When a mission file has been selected in the Settings Application, cycling to the
Navigation application will show the markers and waypoints contained in the file…
If no mission file is required, the “No Mission” option can be selected in the settings.
4.4.3 GPS Diagnostics
When the GPS is connected (and enabled
in the System Settings menu), the “Show
GPS” settings option will show the GPS
diagnostic display.
This shows the current state of the GPS,
including the availability of satellites, their
signal strengths and the current GPS
position fix.
After connecting and powering up the GPS, it can take several minutes for the GPS
receiver to get it first fix. During this time, the GPS status icon ( ) will be yellow, and
once a fix has been acquired the icon will change to green.
The connection status indicator ( ) at the top left of the display will rotate through
90° every time Artemis receives a GPS data message, regardless of a fix being
available. This can be used to verify the receiver is connected and powered up.
The main part of the display shows a polar graph representing the overhead
hemisphere of the sky with the numbers of available GPS satellites in their current
positions. To the right of the display a series of bar-graphs shows the signal strength
available form each satellite.
Satellites whose signal is too weak to receive are shown in red, while satellites whose
information is not being used in the current fix are shown in green. Satellites that are
being used in the fix solution are shown in white.
