Message Type 8

Message type 8 is region-specific. If you encounter any messages in the wild that might be interesting for AIS-catcher to parse...

Jasper,

I am getting messages from fixed structures which show up in OpenCPN Windows Version 5.10.2-0. Is this something that can be added to AIS-catcher?

South Bramble AtoN provides information and meteo data Current, Direction and Water Temp:

SouthBramble-meteo-202410031746

South Bramble AtoN

Likewise the NAB Tower (but atmospheric data):

nab-tower-data

nab-tower-info

Are these type 8 messages perhaps?

From South Bramble

!AIVDM,2,1,2,A,8>jHDhh0Gwu;9Lw9ojm?wvlFR06EuOwgwl>6hhAQR0n6<wwsAwwnSAe,00B ( MSG: 8, REPEAT: 0, MMSI: 992351427, signalpower: -9.23283, ppm: -0.578704, timestamp: 20241130112041)

And from NAB Tower

!AIVDM,2,1,6,B,8>jHC00Gwv@GaLiaOjlQ0iOcP?v<OVvgwl?wnSwe7wvlOwwsAwwnSGm,07F ( MSG: 8, REPEAT: 0, MMSI: 992351136, signalpower: -34.3669, ppm: -2.89352, timestamp: 20241130111901)
!AIVDM,2,2,6,B,wwh000,4

`

Note the screen shots and messages are not the same times so the variable data will be different.

AIS-catcher is providing the data to the network, so the data is present as it arrives at OpenCPN and shows. I think this is a new feature in OpenCPN as I do not recall seeing it in the previous version,

Happy to test / provide more data as always.

Regards
Roger

EDIT: I do not see files attached, please let me know where to send them.

Jasper

assuming my filtering in AIS-catcher is correct: some type 8 and 21 messages

and some type 8 only:

Hopefully the files are included, using the 'code' option to paste messes up the format as it interprets some of them as control characters. If the files are not, let me know and I can email them. I did "Paste, drop or click to add files"

Hope that helps test.

The first message can be decoded using -0 5. However, it will not be displayed in the web viewer, assume that is what you are looking for. Has come up before but did not have the time to implement this. Let's add as a feature request.

Hi Jasper,
Happy to have it on the new feature request list, providing it is not too far down :)
Let me know when to help test.

Yes I am thinking of the web viewer display.
