Cobham SATCOM, May 2015
1Introduction
The SAILOR 3771 Alarm Panel FleetBroadband is the first system to take advantage of non-
SOLAS Voice Distress calling via FleetBroadband. The Alarm Panel and Voice Distress calling
have been developed to enhance safety communication aboard both non-commercial,
fishing, workboat and recreational vessels, through efficient use of the FleetBroadband
service.
2Voice Distress (non-SOLAS)
The Voice Distress calling service provides full priority access in both ship-shore and shore-
ship communication in emergency situations, together with pre-emption for distress priority
call initiated by the activation of the “red button”. Essentially, the service is able to interrupt
any non-urgent calls once the distress button has been activated and give full priority to
subsequent emergency communications and hereby improve the safety on board.
The distress call from the FleetBroadband system is a voice call, which means that the call
will be connected to an operator at the MRCC (Maritime Rescue Coordination Center). Each
Inmarsat satellite region has a nominated MRCC, which assesses the call and directs details
to a suitable rescue co-ordination centre near to the scene of the incident.
Please note that the service is not GMDSS compliant.
Distress pre-emption and priority voice call
Pre-emption and Priority Calls enable the possibility of calling either to or from a vessel in
distress even if the FleetBroandband voice line is already busy in an in- or outbound call. If a
Voice Distress call is made, any existing calls will be terminated.
Pre-emption is for giving the RCC the ability to contact the vessel in distress or a
vessel in close proximity even if the line is busy.
Priority is for giving the Distress call priority over any other call from the terminal.
