When Class B AIS finally gets going, there’ll be yet another issue to deal with: not all existing AIS plotting systems are going to fully understand the Class B messages. Apparently separate messages were anticipated...
You really need the full screen above to see what’s going on, but that’s the “tow builder” feature in Jeppesen Marine’s new ECS product, which previewed at the WorkBoat Show. A tug captain can graphically build a...
Well, whereas I stirred up a bit of a Class B AIS hornet’s nest yesterday, I may as well keep at it! It seems to me that another repercussion of Class B’s 30 second (at...
This diagram—borrowed from Dr. Andy Norris’s valuable AIS/06 conference presentation—illustrates various possible target presentations for a vessel doing 30 knots over a one minute time period. The green dots roughly represent both radar paints and Class A...

This photo shows the AIS receiver test I mentioned a while back. There’s organizer Jeff Hummel of Rose Point Navigation, Doug Miller of Milltech Marine and Cory Sytsma of SeaCAS, plus eight different receivers all set...
The good folks at Shine Micro sent over an update on their own Class B AIS product, RadarPlus, and the general state of the category: * RadarPlus really exists, units licensed for experimental use are...
