Analyze commercial maritime traffic patterns and the security of the AIS tracking protocol.
AIS (Automatic Identification System)
Simultaneous GMSK reception on the two primary marine VHF AIS channels (161.975/162.025 MHz).
Parsing AIVDM/AIVDO packets into ship identities, GPS coordinates, and voyage destination data.
AIS utilizes Gaussian Minimum Shift Keying (GMSK) to transmit high-speed data bursts in the marine VHF band. This simulation demonstrates the transition from raw RF bursts to parsed navigation coordinates.
Like ADS-B, AIS is an unencrypted, unauthenticated protocol that relies on trust; researchers have demonstrated location spoofing risks.
Monitoring marine safety traffic is a standard practice for shore-based situational awareness and safety.
Study marine DSC (Digital Selective Calling) for emergency and tactical vessel communication.
