New AIS Catcher version supports Meteo data from AIS Super Buoys

[markdj57]

Here's one of the buoys that is transmitting Meteo data via AIS.

https://www.irishlights.ie/technology-data-services/metocean-charts.aspx#:~:text=Buoy%3A%20%40SouthHunterBuoy-,South%20Rock,-The%20South%20Rock

And here's the latest Windows Edge AIS Catcher displaying the weather data.

Is anyone else receiving these types of signals from buoys? I am sending the data from ais-catcher into OpenCPN but it doesn't show the weather data and aiscatcher.org doesn't show it either (yet?).

aiscatcher.org does not have it yet indeed…

[markdj57]

There seem to be 2 AIS meteo data info pages coming from the South Rock buoy. One page is the tidal current, though this is displayed in AIS Catcher as wind, as can be seen below.

[jvde-github]

I might have a look but one buoy can share data for multiple locations. Are you saying there is an error in interpretation of some messages where fields are mixed?

[markdj57]

Possibly is an error, yes. Though currently, I don't think the wind is accurate but there are a number of these super buoys around Ireland so it would be interesting to be able to see the data on them live for forecasting and passage planning purposes.

[jvde-github]

I did have a look at the stream you are sharing. And I see for example this in the UI:

09:30:52 - Meteo & Hydro
Wind: 2.0 knots from 337°
Water Temp: 12.8° C
Wave: 0.0 m, 3s

It comes from this message:

!AIVDM,2,1,6,A,8>jHC700Gwn;=ASWv@QoP@>`lr06EuOwgwlwnSwe7wvlO00sAwwnSB0,07B
!AIVDM,2,2,6,A,wvh0,049

Which decodes to:

"dac":1,"fid":31,"lon":-5.365700,"lat":54.408302,"accuracy":false,"day":4,"hour":7,"minute":30,"wspeed":2,"wgust":3,"wdir":337,"wgustdir":334,"visgreater":false,"waveheight":0.000000,"waveperiod":3,"seastate":13,"watertemp":12.800000

I don't see an immediate issue in how we translate data from the message to the UI. But, have no idea how accurate the measurement is.

[jvde-github]

This is btw the South Rock ATON. Your link is very cool: https://cilpublic.cil.ie/MetOcean/MetOcean.aspx but does not contain South Rock. Wish they have this for other countries as well. Perhaps I need to add to the aiscatcher.org map.

[markdj57]

The South Rock is faulty in some way so their twitter feed says, and yes, that's just another link to the same data.

https://www.irishlights.ie/technology-data-services/metocean-charts.aspx#:~:text=Buoy%3A%20%40SouthHunterBuoy-,South%20Rock,-The%20South%20Rock

https://x.com/southrockbuoy/status/1904825903936418163

Maybe it is the wind data that doesn't seem to be accurate, it seems to be higher than forecast and higher than local weather stations on wunderground.

I'm surprised there are no others of these in the world! Irish Lights leading the way then!

still need Meteos?

Thanks for sharing. I did a comparison of the gpsdecode and AIS-catcher with -o 5 and seems to be nicely in line. gpsdecode reports many more fields but AIS-catcher suppresses fields that are not defined as per specification. If that is considered, it is perfectly in line.

Excuse my ignorance: After reading ~all issues I understand that

• local ais-catcher dashboard shows 8/1/31 messages https://www.aiscatcher.org/maxpi_ais/?lat=43.2136&lon=-78.5717&zoom=7.94&tab=map
• aiscatcher.org does not show 8/1/31 messages https://www.aiscatcher.org/?lat=43.2136&lon=-78.5717&zoom=7.94

Further reading for those also interested in binary 8/1/31 messages:

• Message Type 8 #336
• Binary Message 8 #259
• AIS-catcher emits "pressure" as floating point in JSON output, IMO289 specification says it should be integer #179

BTW: Above mentioned Toronto station MAXPI_AIS ID:1111 also catches lots of DAC:316 messages

• Weather Station Message 8/316/1/1
• Wind Information Message 8/316/1/2
• Water Level Message 8/316/1/3
• Lockage Order Message (Seaway) 8/316/2/1
• Estimated Lock Times Message (Seaway) 6/316/2/2
• Version Message (Seaway) 8/316/32/1

[jvde-github]

To add, this is correct, the community page does not show Binary messages. It is a feature of the local webservers. If interesting we can add more message types. I also saw in UK a message that says how many passengers are on board.

Added support to AIS-catcher for number of 6/1 messages. So should now decode:

More for another day

Thanks Jasper: c28b9b8
I guess, we should start a separate thread on generic binary message decoding?

[jvde-github]

Created a simple online decoder, not sure why it can be a bit slow but seems to work:

[Dirk--]

Sorry for delay: Started reviewing Jasper's spreadsheet (deleted erroneous NMEA, added NMEA)

• https://github.com/Dirk--/AIS-testing/blob/main/binary-ais.csv

[jvde-github]

Nice! Thanks. I have harvested a few more examples and can load them in the nmea-decoder: https://www.aiscatcher.org/tools/nmea-decoder

The NMEA is in https://www.aiscatcher.org/static/msgs.json
