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.
