Note for Y cables:
It is important that you connect the power and the RTL-SDR dongle to the Y cable first before connecting it to your device otherwise it won’t charge the device – there is a video about this here:-https://m.youtube.com/watch?v=rXiyzfP94AU

RTL SDR AIS RECEIVER

RTL SDR AIS App and AIS Share App

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.
