Heading sensor off kilter??

Heading sensor off kilter??

Postby pcolom1 » Mon Jul 10, 2017 11:12 am

Seemingly randomly my heading sensor seems to be 10-15 degrees off when for about 2 years, since I installed it into a pre-existing navnet 3d setup and a navpilot 500. All worked well for quite some time. Heading sensor is firmly mounted so it hasnt moved. But, I am running full spead at a heading I can read on my compass and a COG i can see on the plotter but the heading line and the little boat simbol or cockeyed to starboard.

Any ideas on what this could be or how to remedy?

Thank you for any help

Although you haven't moved your compass, other things get added or moved on boats. You should start by recalibrating your compass to the boat and see if it lines up.

Thank you for the reply. So do I re calibrate my compass via by Navnet 3d or via the autopilot? Can you please point me in the right direction of a walk through on how to properly do that?

Thank you for the help.

pcolom1,
Since you have the Navpilot 500, I'm assuming you are using the PG500 Heading Compass?
I've attached a link to the PG500 operators manual. Pay attention to page 10 (3.3 Correcting Magnetic Field Distortion) which will tell you how to perform a calibration of the compass.
