6.3.2 Navigation Using the GPS Float
The following operational procedure is recommended when underwater navigation
using the GPS Float is required.
 If required, use the Artemis Manager PC software to prepare a Mission File
containing the positions (latitude and longitudes) of search-pattern waypoints or
targets of interest to navigate to. Use the USB cable to download the mission file
onto the Artemis console.
For more information on Mission Files, see page 35.
 Check that Artemis has been prepared in accordance with the instructions in this
manual, and the pre-dive checklist above, and is fitted with the GPS Float.
 Once the unit is switched on, the GPS signal will obtain a fix after a few minutes
providing that a satisfactory GPS signal can be obtained.
The quality of the GPS Position displayed on the screen should be compared where
possible to another GPS source (from the RhiB or operating platform to confirm
correlation).
 Cycle through the Artemis displays to the Navigation Application, then (if defined)
select the required destination marker (waypoint or target) from the Mission file.
The Range and Bearing to the destination marker will also be displayed. The diver
can use the Navigation system for guidance to the datum as indicated.
 When the Artemis console is submerged, the Dive Log file start recording (if the
immersion sensor is enabled) – alternately, start logging using the “Start Dive”
option from the Settings display.
 Should the diver chance upon an unknown target during his sortie, the position of
the target can be marked by pressing the “Mark Target” button on the console.
This will record the geodetic position of the target.
The accuracy can be improved by the diver drawing the surface float above him to
reduce the lay-back offset described by the position of the float at the point at
which the position is recorded.
 In total, Artemis can hold 20 markers in a Mission. When specifying pre-dive
targets, ensure the mission file has sufficient space for any additional targets to be
marked during the dive.
 Upon return to the surface, connect Artemis to a PC through the USB cable, and
download the relevant “Dive Log” files. These can be opened in the Artemis
Manager PC application, and data analysed or exported to third-party applications.
