Distress signal received
A rescue centre has received an alert — from a beacon, a radio call or a satellite terminal — and is asking ships to look.
Position (degrees and minutes)
How warnings write positions: degrees, a hyphen, then minutes, with N/S and E/W — 49-40.8N 003-43.8W.
Date-time group (DTG)
A compact UTC timestamp — day, hour and minute followed by Z — such as 201500Z for the 20th at 15:00 UTC.
Keep a sharp lookout
A request to every ship in the area to watch for the vessel, people or object described.
Assist if possible
The second half of the standard rescue request: ships able to help are asked to do so.
RCC / JRCC (Rescue Coordination Centre)
