Safety Of Life At Sea - This International Convention is the most important treaty protecting the safety of merchant ships. It divides all vessels in 2 groups: SOLAS and non SOLAS vessels. SOLAS vessels need to comply with GMDSS sattelite and radio equipment carriage requirements. SOLAS vessels are all cargo ships of 300 GRT and upwards and all passenger ships with some exceptions. Detailed SOLAS vessels definition may be found in ALRS Volume 5. Non SOLAS vessels do not need to comply with GMDSS radio equipment carriage requirements, but will increasingly use it, because that causes an important increase of the safety at sea. Some countries have incorporated GMDSS radio equipment carriage requirements into their domestic marine legislation that is valid for non SOLAS vessels under their flag.

Short Range Certificate - Just as every driver needs a licence to drive a car, operators of marine radios also require a licence. The person operating VHF radio system sailing in GMDSS Sea Area A1 must be qualified to a minimum standard. This standard is the GMDSS SRC.

Coordinated Universal Time - It is a high-precision atomic time standard. Time zones around the world are expressed as positive or negative offsets from UTC. Local time is UTC plus the time zone offset for that location, plus an offset (typically +1) for daylight saving time, if in effect.

VHF Channel - The marine frequency band for VHF radio communication, extending between 156 MHz and 174 MHz, contains 57 individual VHF CH (channels) numbered consecutively from VHF CH 1 to VHF CH 28 and from VHF CH 60 to VHF CH 88.

is a transmitting-receiving system, which allows the operator to either transmit or receive information on the marine VHF (Very High Frequency) band

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

World Wide Navigation Warning Service - It is a co-ordinated global service for the promulgation of navigational warnings. In GMDSS Sea Area A1 and A2 they are broadcasted via NAVTEX system, and outside given areas via SafetyNET system.
