Remember : The Radar Heading Line is a one-time setup. Once
you have it corrected, there should not be a regular need to
adjust this setting. Alignment issues while underway are typically
a function of compass deviation challenges.
Creating a Compass Deviation Table
Due to magnetic interferences and other considerations, magnetic compasses
can provide inaccurate information. To complicate this matter, the level of heading
inaccuracy can change at each compass heading. To resolve this, inside the
Nobeltec software is a table that allows you to enter correction values at each 5
°
increment.
Tip : Using a Combination GPS Heading sensor that determines
heading based on dual GPS antennas instead of magnetic
significantly improves the accuracy of incoming heading data and
simplifies the radar alignment process.
Once you have resolved the radar heading line and compass master rotations, you
now need to test the radar alignment at various headings to discover the onboard
deviations. The easiest way to do this is to be on the water in a clear open area and
drive at each heading for a short while correcting the deviation as you go.
An example of a way to do this follows:
