What is difference between RACON and RAMARK ?

• A Racon is a radar responder beacon.
• Its name is derived from Radar beacon.
• When the ship’s pulse arrives at the Racon, the Racon amplifies and returns the pulse to the scanner as a fairly strong signal of the same frequency. This signal creates a short, bright line on the PPI.
• It gives Bearing and range of the Racon.

RAMARK

Ramark (RAdar MARKer) is a radar beacon used to mark navigational hazard which transmits either continuously or at intervals. The latter method of transmission is more used so that the PPI can be inspected without any clutter introduced by the Ramark signal on the scope. The Ramark  signal as it appears on the PPI is a radial line from the Center. The radial line may be a continuous narrow line, a series of dashes, a series of dots, or a series of dots and dashes.
