MCC

Mission Control Centres - Their main purpose and function is to relay EPIRB Distress alert information to the appropriate MRCC who coordinates the deployment of SAR units in the SAR region in which the casualty is located.

MES

Mobile Earth Station - The generic name used to describe an Inmarsat-approved terminal which is allowed to access the network, and applicable to both maritime and land mobile communications.

METAREA

The world is divided into 16 (plus 5 polar - not operational yet) METeorogical AREAs. This are regions of the seas, with same outer boundaries as NAVAREA, for which specified nations have the responsibility for the co-ordination of the provision of meteorological information. METAREAs are usually divided into sea areas for weather forecast broadcast using EGC, NAVTEX or voice messages through VHF, MF or HF.

MF

Medium frequency - same mean as medium wave (MW). Frequency bands from 300 to 3000 kHz. For distress calls in sea area A2 MF frequencies should be used.

MF/HF DSC radio

It is a transmitting-receiving system, which allows the operator to either transmit or receive information on the marine MF (Medium Frequency) and HF (High Frequency) band only by DSC (Digital Selective Calling).

MF/HF radio

is a transmitting-receiving system, which allows the operator to either transmit or receive information on the marine MF (Medium Frequency) and HF (High Frequency) band.

MF/HF RT radio

It is a transmitting-receiving system, which allows the operator to either transmit or receive information on the marine MF (Medium Frequency) and HF (High Frequency) band only by voice.

MMSI

Maritime Mobile Service Identity - MMSI is a unique 9 digit number and acts in the same way as a telephone number. The MMSI allows radio operator to make automatic calls through VHF DSC radio and is the identity that is automatically transmitted within DSC calls. These MMSI numbers are issued by the appropriate authorities in the country of registration of the vessel and can be referenced back to a database of information about the vessel and it’s owners and so forth.

MRCC

Maritime Rescue and Coordination Centre - All SAR activities are organized by MRCCs and MRSCs within specified navigational sea areas normally bordering their coastlines.

MRSC

Maritime Rescue Sub Centres - All SAR activities are organized by MRCCs and MRSCs within specified navigational sea areas normally bordering their coastlines.
