5.6 ais target heading issue

[kcj]

Running openplotter on rpi4… just upgraded from open on 5.2.4 to 5.6..

In doing so, any ais target icon with a null heading is defaulting to 000, instead of COG…thus targets moving EAST with no heading are pointing NORTH…under 5.2 they were pointing to the COG…

How do I get these to default to 5.2 approach?

An issue with 5.6? Some setting?? Something else?

Thanks in advance
John

Neither on Win nor RPi I don't see that. See my shot from a RPi4. No heading but the ship symbol is pointing to COG.
I the case no speed of the ship the symbol would though point north since no speed also implies no COG.

Thx for feedback
Are you using openplotter with opencpn5.6?? Was not an issue with 5.2….

See my pix
Boat is going west, icon pointed north….

Not on the boat to test myself today, but I see the OP doesn't have the leading line feature turned on for AIS targets and Hakan does. Any chance that makes a difference in how the icon is processed?

[Hakan]

The course predictor would have no impact on this.
John..
Looks really strange. What is the difference to the class B target south for the actual target where the ship icon seems to point to COG?

[kcj]

Any target pointing the right direction has a non-null heading… anything with a null heading (and a non null cog) defaults the icon heading to 000

[Hakan]

But the class B target southwards couldn't have a heading. It's not included in the class B messages.

[kcj]

Furthermore…
Class does not seem to matter, nor boat speed. Btw my course predictor is checked but rarely works…also the only way I can get target tracks is by clicking the record option within the target query box… the show target track does nothing…

[kcj]

Some class B boats do have a heading…maybe 20-25%.

This all changed going from 5.2 to 5.6…was fine on openplotter using cpn5.2….

BTW: I'm using Win10 and RPi3,4,400. Both O v5.6 and the beta from here: https://www.cruisersforum.com/forums...ed-262505.html

John..
Sorry, I've never seen what you describe so not much of a help.
Anyone else...?

[kcj]

Could this be an openplotter issue?? A Linux issue??

Hakan
Many thanks…

After three reinstalls, and several hours of playing with the options/ships/ais switches the target icons corrected themselves...there is a gremlin in there, but i can no longer replicate it...

Possibly there were too many anchored boats, at least for the initial boot up. Cuz its fine now....

Thanks to all for a great nav system .

Cheers

Gremlins are there to strengthen our character. If it happens again please come back. Possible with a VDR recording?.

Thanks for the report.
