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.
