What frequency does AIS transmit on?

AIS (Automatic Identification System) is a vital safety and navigational tool used in the maritime industry. It transmits information about a vessel's identity, location, and course over radio waves in order to prevent collisions and aid in navigation.

The frequency used for AIS transmission is typically 161.975 MHz and 162.025 MHz, which are reserved internationally for AIS use. These frequencies have been carefully chosen to provide optimal transmission range and clarity of signal.

The use of AIS has greatly improved maritime safety, allowing vessel operators to easily track and avoid potential collisions. With the widespread use of AIS, accidents and collisions on the open seas have significantly decreased.

In addition, AIS has also improved navigational efficiency and logistics for the maritime industry. Operators are able to track their vessels in real-time, identify potential delays or obstacles, and make more informed decisions to optimize their routes and schedules.
