Q

In general, on how many radio channels will an automatic identification system (AIS) operate?

🔍 Key Concepts

• AIS (Automatic Identification System) basic purpose and how it exchanges data • Use of VHF marine frequencies for AIS • Difference between main operating channels and other related frequencies

💭 Think About

• Think about how many distinct VHF channels are dedicated specifically to AIS transmissions worldwide, not how many total VHF channels exist. • Recall that AIS normally uses a pair of primary frequencies so vessels can still communicate if one is busy or blocked. • Consider whether additional channels (beyond the primary pair) are routinely used for standard AIS ship-to-ship and ship-to-shore operation.

✅ Before You Answer

• Confirm how many primary AIS channels are assigned internationally for AIS traffic. • Distinguish between AIS operating channels and any backup/auxiliary frequencies that might not be in continuous use. • Make sure you are not confusing AIS with DSC (Digital Selective Calling) or general VHF voice channels.
