Anyone who navigates with a tablet and wants to use AIS data can fall back on internet-based systems such as Marinetraffic. However, their data is not transmitted in real time, which means that the express ferry that has just been identified may already be somewhere completely different from what is shown on the map. In addition, the online data can usually not be integrated directly into the navigation apps. The iAISTX from Digital Yacht is supposed to solve the problem. It is a fully-fledged class B AIS transponder with its own GPS receiver. In the basic version, it provides the received ship data via WiFi and is compatible with common navigation apps such as Navionics, iNavX, NavLink, Time Zero, Weather 4G, SailGrib, Open CPN and iRegatt.
The iAISTX works either in client mode in an existing WiFi or as a hotspot if no other devices are on board. The configuration takes place via the integrated web interface, via browser. Special apps are not necessary.
The Plus version also has a NMEA2000 interface, so that plotters that cannot process AIS data via WiFi can also be connected.
The iAISTX should cost 630 euros, the plus version is available for 780 euros. Both devices require their own VHF antenna or a suitable splitter.
