2. GMDSS ~~~~  Regulations and Rules

GMDSS is a combination of regulations and rules for shipping and radio communication.
2.1.1 Safety Of Life At Sea SOLAS

The SOLAS Convention is concerning the safety of merchant ships. It was adopted in 1920, in response to the Titanic disaster 1914. In1988 Chapter IV radiocommunication of the Safety Of Life At Sea SOLAS convention incorporates GMDSS. SOLAS was adopted 1960 by the International Maritime Organisation IMO.

The IMO is a specialized agency of the United Nations UN and based
in London.
2.1.2 Radio Regulations RR

by a contracting government. 30nm from coast
2.2.2 A2 - Medium Frequency MF
An area within radiotelephone coverage of at least one MF coast
station in which continous DSC alerting is available, as may by de ned
by a contracting government (excluding A1). 150nm from coast
