Marine forum

Post by srcejon »

The Marine forum is for the discussion of SDRangel's marine related plugins (AIS and Navtex).

The Automatic Identification System (AIS) used by ships to broadcast their position, velocity and other status information. AIS data packets can be received and demodulated by the SDRangel AIS Demodulator and then tabulated and plotted on a map by the AIS Feature plugin. AIS is typically broadcast on 161.975MHz and 162.025MHz. The AIS Modulator plugin can be used to transmit AIS packets (but this must not be done on the aforementioned frequencies).

Navtex messages contain marine navigational and meteorological warnings and forecasts, broadcast worldwide on 518kHz.
