5.10 DSC
The DSC (Digital Selective Calling) is a method of establishing a VHF radio call; it is
used to announce urgent maritime safety information broadcasts. This system allows mariners
to instantly send Distress Call or/and Position Request to the other vessels equipped with a
DSC transceiver within range of the transmission.
The Distress Call, that allows to receive a position of the vessel in distress, and the
Position Request, a great feature for anyone wanting to know the location of another vessel
- for example you buddy that is catching fish, or finding the location of a person you are
cruising with, are performed by an external device, the DSC VHF radio. The chart plotter
interfaced with a DSC VHF radio prompts the user to see the GPS position of the vessel
in distress and also allows for easy navigation to the vessel.
The Distress Call and the Position Request icons that are displaying on the screen,
are shown in the following table:
