Bug fixed in the dashboard. How to upload it ?

• dashboard_pi::SetPositionFix(PlugIn_Position_Fix &pfix)
• navigation.gnss.satellites event
• navigation.gnss.satellitesInView event

There is probably a bug in this part of the prioritization code ?

Could be... I can do some tests as well. I'll later force my GNSS through SK instead of a straight UDP as the example picture. Shots taken every 30 seconds.

But the fly in the ointment is if the GPS receiver generates a position fix using a combination of constellations, in which case the talker id is "GN". I think you may require a little more logic in the dashboard plugin to render each of the different GNSS satellites.

The talker for "GGA" is "GN" when several system are used. Correct.
The talker for GSV depends on submitted sat system. That's also used by present OCPN. See my previous post.


BTW: In signalK when using N2K positions could you view a shot with the "data browser" similar to mine here: https://www.cruisersforum.com/forums...ml#post3575576
The aim is to see how the "source" is reported in your case.

Pierre..
The prioritization bug for SK "Satellites used" found. A silly mistake. Good you started this with the hint of the way to find the Talker for SK data so it was found.
So how to PR this? Should I pass my finding to you to incorporate in you PR, I can comment there, or should I PR this and my way to catch the talker?
Pls advice.

I also think the SK parse of GSV data is not the best. Satellite data are not as stable as from direct NMEA0183 GSV. That's when I study SK Data Browser.

@Hakan,

just realized that there was a reply to the PR from "hakansv" in my github page. Is it you ?

pmx..
Yes.
