19.7 POSITION REQUEST
Advancements in DSC have made it possible to poll the location of another vessel and show
the position of that vessel on the display of the CPV550 making it easy to navigate to the
location of the polled vessel. This is a great feature for anyone wanting to know the position
of another vessel. For example your buddy that is catching fish, or finding the location of a
person you are cruising with.
NOTE
The other vessel must have an operating GPS receiver connected to its DSC transceiver and must
not have its transceiver set to deny position requests. (Refer the section “19.4.0 Setting up the
Individual / Position Call Directory” to enter information into the individual directory).

of your vessel that you may not want to. In the manual mode you will see the MMSI or

requesting vessel.
