3 ways to bring gps to OpenCPN and Pypilot in OP2

I don’t even think you need to ? The compass calibration is required, the rest figures it’s self out, even the compass calibration figures it’s self out on the water
it is difficult/impossible for the compass calibration to work if there are too many magnetic distortions. If it worked on the boat it can likely work in your house, but you must absolutely not move it in space in the house the entire time it is running which is impossible (for some people) Otherwise the changing magnetic field across space inside the house may block the calibration update for many minutes.

For my entry into Pypilot I would have liked a detailed overview of the configuration. After a lot of research and trial and error, I have clarified some problems.

Because other users might have similar questions, I recorded an overview of the connections for the GPS signal in OpenPlotter 2.

I hope it can help some people to understand the system.
If there are still proposals for changes, please let me know. Maybe it can be added to the OP manual.


This is useful information. I have been grappling with the connectivity and a diagram as per the above is really usefulI think it should be included in the documentation section and also the document! I'd offer to help with this but i'm only just starting on my learning curve.
I confirm that this diagram is useful to understand the possible connections. Note that we can now connect OpenCPN directly to SignalK on (default) port 3000... although this causes network congestion problems in my case. Here is my configuration and a question:

My network:

My opencpn connections settings:

[Image: port-20220.png]

Question: I changed the priority of port 20220 because OpenCPN was not consistently showing me the compass orientation of my boat. This way it's better but not perfect... even if it's rarer, it ends up not taking this information into account. Maybe there is a way to filter the information received so that OpenCPN selects what it needs on ports 20220 and 10110 via "Input Filtering"?
