AISWiz
(AIS graphic software)
As of 2004 all ships over 300 tons must broadcast over the
radio all sorts of information about them selves, using
AIS short for Automatic Identification Systems. With the
right type of equipment you can receive this information
and display it graphically on screen. AISWiz takes GPS and
AIS input, decodes the incoming AIS messages and displays
all sorts of information, about ships within VHF range,
on the screen. You can see a ships course, speed, range,
bearing, closest point of approach, and much more. You are
also provided with information like the ships name and call
sign so you can call it up if need be. The display is like
a radar, but as opposed to radar AISWiz is very easy to
use.
