[TG] [TG11] AIS information on internet

[Rom]

Hi all,

Not directly a Raymarine question but very relevant. I understand the difference between a Class A and Class B but i'm still unsure about journey details.

There seems to be no way of setting origin or destination with a class b transeiver ( particularly the AIS700 or AIS650), this feature is only available on a class A. However, when looking at online tracking websites ( Vessel finder, Marine traffic) journey details appear for some vessels that are definitely equipped with class b systems rather class A.

Question is: do these websites just automatically establish journey details from track and heading or are they entered some other way?

Many thanks,

Rom
