iNavX allows you to connect, since version 3.1.7 from February the 11 October 2010, to the data server AIS SiiTech which I talked about in a previous post (¹). The interest of this service remained questionable in France because of the poor coverage of our coasts. That could change.
Indeed, the number of SiiTech ground stations is increasing, the Channel coasts are now well covered, and the Atlantic coast should be gradually equipped (²).
In addition, The version 3.2.4 of iNavX comes with an improvement that makes a revival of interest for this feature : it is now available to select the origin point of AIS data from SiiTech server, or the position of the ship (that of the iPhone/iPad used), or a previously created waypoint. The reception radius being about 30 nautical miles around place of origin, this allows for a significant increase in the coverage of AIS data reception.
You are probably aware that the release of the new iOS4 operating system for iPhone and iPod Touch will be available today during the day, via synchronization of your (s) devices with iTunes. For the iPad, We will have to wait until the autumn.
