"Automatic Identification System (AIS) is used for identifying and
monitoring maritime traffic..."

"The AIS is a shipboard broadcast system that acts like a transponder,
operating in the VHF maritime band, that is capable of handling well over
4,500 reports per minute and updates as often as every two seconds. It uses
Self-Organizing Time Division Multiple Access (SOTDMA) technology to meet
this high broadcast rate and ensure reliable ship-to-ship operation."

Perhaps a bit more like APRS ver 2. We might have some catching up to do.
