AIS is mandatory in Austria since 2008, and skippers transmitting incorrect data like in the examples will get in trouble (fined).
In Belgium it's mandatory in sea ports
Inland ships are only allowed to use inland AIS, but it seems that some brands of AIS equipment
are transmitting SOLAS data too (which has not been entered because it becomes unavailable once the equipment
is set to inland).
Also, a lot of these ships use chartplotter
software to program the AIS, and there's quite some problems with that resulting in incorrect data being transmitted, like incorrect ship types or operation modes.
Software updates are only required in case the regulations
are changed since they became "final", or for software that should have never been approved.
That is the largest problem with all this.
The equipment has to be re-approved, software updates installed and documented.
This means all parties involved (government, manufacturers, installation
companies and the skippers) have to do work that they will want to be paid, but who's going to do that ?
Especially because not everything was known or taken in account while drafting the regulations
