Satellite AIS

I'm not sure if this is the correct forum or not but an interesting look at how governments are using Satellite AIS.

Re: Satellite AIS

Interesting but keep in mind that satellite AIS only works with class A transponders. The signal from a class B is not powerful enough to be picked up by the satellites (for now).

interestingly

"Both Class A and Class B AIS transponders are detectable by S-AIS, however Class A transmissions are more likely to be detected for the following reasons, among others:" IMS Global

Ok, that's new for me. I like it. This can be a huge help if we ever are overdue or lost at sea.
