AIS, this ‘n’ that #4

* Thanks to Panbo reader Derek for a link to AISLiverpool, the neatest AIS plotting Web site I’ve ever seen, especially since AISlive, and then Xanatos, became mostly subscription services. I’m not sure this will please the IMO, which is trying to limit AIS Web broadcasting, but it certainly is a great place to see how well the technology works. The example above, cropped from the full screen shot, illustrates how AIS is now being used to mark significant fixed objects, as well as ships. AISLiverpool is also endless fun for harbor gawkers, adding Web cams, photos, track histories and more to the AIS data. The site seems to be the work of an enthusiast, but I can’t find a link to the author (anyone?), who deserves applause I think.

* Check out Maritec, makers of just about everything AIS including test hardware and software. The news section suggests that the Class B AIS standard is finally done (maybe someone can confirm?).

* And here’s an interesting conversation about diddly but important NMEA 0183 details involved with getting an AIS receiver connected to a Raymarine C or E. Meindert Sprang, of ShipModul, provides expertise as usual.

* Finally, note how a Brookhouse Multiplexer made Jan-Enno a “happy man” by letting him hook a new SR 162 AIS receiver to both his Raymarine C80 (along with SeaTalk instruments) and his laptop. He explains how it works in the “user comments” section at the Brookhouse site.
