The satellite system should allow for addressing a maritime
distress alert to a specific MRCC chosen by the ship’s operator
and covering the area concerned, but should also provide for automatic
routeing of manually initiated maritime distress alerts. Means should
be provided to allow the MRCC to easily identify the system and specific
mobile station from which an alert or other priority message has been
received, to enable the MRCC to establish shore-to-ship communications
with the ship concerned.
