Aligning the Radar Image
Getting the radar to properly align with the electronic chart requires a few key
devices and software settings. As a summary, these three are:
Compass Master Heading Correction : In certain cases, it is not possible to install
the digital compass exactly parallel with the vessel center line. This software setting
allows an offset to be entered into the program to compensate for this occurrence.
Radar Heading Line : For similar reasons to the compass, it is not always possible
to install the radar with the front of the radar exactly paralleling the vessel’s keel
line or center line, the Radar Heading Line adjustment can compensate for this
occurrence.
Compass Deviation : Magnetic compasses can give incorrect readings for many
reasons. The most typical is magnetic interference on the boat. The engine block, a
large anchor and rode, and even electronics can create magnetic interference. The
Nobeltec software allows you to enter in a deviation table that tells the software how
to adjust the incoming heading data to compensate for these local deviations.
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
