The RangeGuard Display presents positional information in one of three main formats,
Bird’s Eye View, Table View and Single Sensor View.
Bird’s Eye View (BEV)
The BEV depicts the operational area of the RangeGuard system from above. By default,
the BEV is centred on an image of the vessel and around this it shows a radar beam, range
measurement and received signal level for each sensor that has detected an object.
Clicking on any one of the radar beam sectors causes a shift in the BEV so that the object
detected by that beam is now at or close to the centre. The colour of the beam changes
to reflect the range of the object (red, amber or green in accordance with configured alarm
limits). The colours of the other beams also change to reflect the ranges of the objects that
they have detected.
In order to switch to the BEV from one of the other views, click on the
Bird’s Eye View button in the top right of the display screen:
Bird’s Eye View without a sensor in focus
Bird’s Eye View focussing on one sensor
The contents of the BEV can be enlarged or reduced by means of the Zoom In and Zoom
Out buttons in the bottom right of the screen. Six zoom levels are available and the current
level is indicated by the yellow bars between the buttons:
The position represented by the mouse cursor on the BEV, taking into account the zoom
level, is displayed above the zoom buttons, e.g. Mouse at 117°, 68.10 m from vessel
centre. These numbers are updated as the cursor is moved across the screen.
