The description "Racon" beside an illustration on a chart refers to which type of beacon?

The term "Racon" refers specifically to a radar transponder beacon used in marine navigation. A Racon emits a series of radar pulses that are reflected back to radar systems on vessels, providing information about the beacon's position. This technology essential for improving situational awareness, particularly in areas where visual navigation aids may be absent or less effective.

Racons are particularly useful as they identify themselves through a characteristic pattern, which makes them distinguishable on radar displays. They enhance navigational safety by allowing vessels to determine their position relative to the beacon, often in adverse weather conditions or during nighttime operations.

The other types of beacons mentioned serve different purposes in navigation and may involve visual signals or different communication methods, but they do not function in the same way as a radar transponder beacon like the Racon.
