SAR helicopter incorrect country flag?

g7ruh opened this issue · comments

Just noticed this:

SAR flag wrong-query

which shows the wrong flag on the pop up panel and on the hover over the "vessel".

This from TAR1090, squawk 7000 as it was training not on a SAR mission:

tar1090-CG175

The MMSI is from a portugese cargo vessel....

It seems to have now landed..... Really odd

Hi All, this has been showing like this for about a week, I think it may have had a new AIS box which is somehow coded wrong.

I can confirm it is a real helicopter, as it flies over my house, certainly not a flying ship!!: too small for that :) It looks like the pictures above, rotor blades and red and white body. Callsign for marine frequencies CG175.

thanks @Jonboy1081 for your reply.

Jasper,

It was just working with squawk 0023 as rescue175. Thanks for the reason why (and to @Jonboy1081 too).

I just saw it and wondered if it was a bug or human error, seems like the latter. Sorry for the "herring rouge"** as we say in England.

I will see if I can contact HM Coastguard to inform them of the data issue.

Roger

** I will explain further if anyone is curious.

Thanks for flagging, it is an interesting case and something to think about how we can avoid this corrupting a database

suggestion: double check with MMSI and others sites to test coherency

It is OK now on MT

I suspect that the SAR helicopter has set the MMSI incorrectly. I have informed HM Coastguard by email.

Update 19th May 2024

Independent Primero came to Southampton and left Friday.

AIS-catcher chart swapping between vessel location and SAR helicopter location based on last received message. I guess somebody noticed it and got the MMSI fixed. I never heard back from HM Coastguard. All is well now.
