The ROV compass system is designed to display headings relative to Magnetic North. You can enter a local compass variation to
account for magnetic declination. The declination is considered positive when the Magnetic North is East of True North.
The value you enter is numerically added to the heading from the ROV. For example, if you are in an area with a declination of 15
degrees West, the ROV heading will read +15 degrees when the ROV is facing True North (assuming no variation has been
entered). You should therefore enter 15 for the variation, which would result in a correct True North reading of 0 when the ROV is
pointed True North.
The declination is saved from session to session. Be sure to clear it or change it at the start of each session if necessary.
Beginning with version 1.8 of VideoRay Cockpit, the behavior of the Compass Variation has been reversed. In prior versions, the
variation was subtracted from the ROV heading.
You can use the
Turns Indicator instrument
to facilitate easier navigation with respect to a fixed reference such as a dock. See the
sections on the
Turns Indicator instrument
and
Relative Heading
for more information about using the Turns Indicator settings.
Compass Calibration
For best results with VideoRay CoPilot RI, the compass calibration should be completed to optimize its performance in your location.
