2.7 GPS POSITION ON A VHF RADIO
STANDARD HORIZON has pioneered Digital Selective Calling (DSC) on VHF radios.
Advancements in DSC have made it possible to show the coordinates of a vessel that has
transmitted a DSC Distress Call or even Poll the location of another vessel and show the
position of that vessel on the display of STANDARD HORIZON VHFs.
STANDARD HORIZON has taken this feature one step further, if the GPS Chart Plotters
are connected to a STANDARD HORIZON DSC capable VHF, the vessel in Distress or the
polled position of the vessel is shown on the display of the GPS Chart Plotter, making it easy
to navigate to the location of the vessel. This is a great feature that could save someone’s
life or for anyone wanting to know the position of another vessel.
