WHAT IS IT ?
It is an Android app / application that decodes AIS messages transmitted by ships via 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 application does not need an internet connection, it decodes the received messages in real time.
This is a true standalone full featured AIS receiver.
The received messages are translated into NMEA0183 strings which can then be forwarded via UDP or TCP streaming to third party applications, PC programs or other devices.
Such applications can, for example, display the received AIS data on a map together with information about the received objects.
Please note: The app needs additional (very cheap) hardware to receive the radio signals.

Can you help me to use USB CAN bus? I can explain in more detail in the mail.
Sorry -just made some test with can bus long long time ago. But I am really not an expert
Hello, I have the Rtl ais driver, but I have already reached 1000 msg, the problem is that I already have the rtl share and I cannot reactivate the rtl driver, How can I make it work?
You should use the AIS SHARE app. You do not need the Test Mode in RTL AIS Driver. It is a test mode that works for 1000 msg.
Don’t forget to go to the settings menu in AIS SHARE. All settings you used at RTL AIS Driver will not taken over to AIS SHARE. Use only the app AIS SHARE, and just keep RTL AIS Driver in your mobile device.
