2 The information in transit, are they sent and received by the transmitter and the receiver AIS of the boats?
No, they are sent by a data connection to the server. So, if you use the public server then you must have a data connection to GPSGate.com. If you (and the other vessels) have a private server then all must have some type of data connection to the private server. Each vehicle/vessel/person that is being tracked runs the GPSGate Client software
(which also does the data splitting mentioned above). The client reports the position to the server, and reads the positions of "buddies" from the server. There are many platforms where you can run the client. In order to see other vessels on your display you will need a connection to the server, and they will also need a connection to the server so that they can report their position.
It really does not have anything to do with AIS, it is just in the same place because the tool displays the location of other vessels on the map as do AIS/DSC.
