Is there a way to add in my known gyro error so my display doesn’t have me slightly skewing my way down the river? My COG is going right down the range, but my 3.4W (for now) gyro error makes it look off, and I have to add it into the courses when I change route legs.
If the gyro is just always off by the same amount, you can adjust the “Installation Angle” on the heading sensor’s page. To get there, use “Settings > Electronics” then pick the device or interface for your gyro. You should see a box called Sensor Settings that shows a list of sensors associated with that device. Click on the Heading Sensor in that list to access its settings.

Thank you Brad, That is great info! My problem is that the installer is pulling data from a Simrad networked NEMA 2000 system and it appears that the heading data is pulled off of the auto pilot not the gyro directly. This has the advantage of being able to feed multiple sources into the autopilot, selecting the one we are using and pushing data to the ECS without any difference to the ECS. Short answer is the Sensor Settings don’t exist in my application.
Thank you
There should be sensor settings even with heading getting to ECS via the autopilot, they just might be a bit harder to find than the way I described. If you’re using a Nemo Gateway to interface with the NMEA 2000 network, then your Electronics page will show the gateway and each of it’s ports…click on the “NMEA 2000 Interface” port and your Sensor Settings should be on that page. If you still don’t see the Sensor Settings box, our support staff can probably help out if you contact them directly.

I think I found the way to spoof it in the Simrad offset settings.
Thank you for the help
I had the same problem as heading data from the AIS device was taking priority over the autopilot heading sensor.
If you’re using an Actisense device for your NMEA2000 gateway (like an NGX-1), you can use their free software to adjust the device instance numbers. Details can be found here.
On the Simrad NSO evo2, I was able to dial it in by accessing the Settings>Network>calibration>Heading>Offset >and subtract my westerly error…
I will see if it worked the next time I am running ranges up the San Joaquin river (that will be tomorrow…)
It’ll be interesting to see what happens when the autopilot is running. Might be just fine but note that the autopilot might be using a different sensor than CE. By changing the offset system wide, the autopilot might try to correct for the new offset. Just something to note if it doesn’t work as expected.
