🔍 Key Concepts

• AIS (Automatic Identification System) uses radio frequencies, not radar pulses • Difference between radar bands (X-band 3 cm, S-band 10 cm) and radio bands (VHF, UHF, L-band) • Standard GMDSS/bridge equipment frequencies used for ship-to-ship and ship-to-shore communication

💭 Think About

• Which choices describe radar operating bands, and which describe radio frequency bands used for communication? • AIS is designed so that even small vessels can carry it and communicate with other ships and shore stations; which band is already widely used for marine voice and digital communications? • Think about which band is associated with normal marine radiotelephone channels (like channel 16) and whether AIS would logically be placed near that range.

✅ Before You Answer

• Identify and rule out options that are clearly radar bands, not radio communication bands • Recall that AIS must be able to communicate with coast stations and other ships over relatively long range at sea surface level • Confirm which band is associated with standard marine radiotelephone channels in the Navigation Rules and GMDSS materials
