WHAT IS IT ?
It is an Android app that decodes AIS messages transmitted by vessels , ships, over radio using a cheap USB DVB-T / RTL-SDR stick.
AIS messages are transmitted over VHF.
Channel A: 161.975 MHz
Channel B: 162.025 MHz.
The app decodes both channels simultaneously.
This app needs no internet connection, it decodes the real time received messages.
This is a truly standalone full featured AIS receiver.
The received messages will be translated into NMEA0183 strings which can be forwarded then via UDP or TCP streaming to third-party apps, PC programs or other devices.
Such Apps can display the received AIS data for example on a map along with information about the received objects.
Please note: The app needs additional (very cheap) hardware to receive the radio signals.
You have an Android device ?

RTL AIS DRIVER
This is the free driver app, it’s needed in any case.
In the driver app there is demo/test mode implemented.
Mainly to test the app if your hardware is compatible.
Please use this demo mode before you buy the full version. The demo mode is limited to 1000 received AIS messages.
- Nice user friendly GUI
- Share AIS data with your favorite chart plotting app like OpenCPN, Navionics, BoatBeacon, MarineTraffic, …
share data with 3 different UDP clients or let AIS Share act as an TCP server ( limited to one client)
- GPS location data forwarding (UDP)
- no limitation on received AIS messages
