Certification Banner


The GMDSS General Operator's Certificate qualifies the holder to operate any suitably licensed marine radiotelephony and satellite mobile earth station.

The GMDSS General Operator's Certificate is an internationally recognised document which qualifies the holder to operate any maritime communications terminal to be found on GMDSS fitted vessels.

We are MCA approved to run GOC and ROC courses and have run over 300 GMDSS courses to date with a better than 90% first time pass rate. 

All our instructors are ex Coast Station Radio Officers and GMDSS Examiners.  All teach at other major nautical training establishments.

Entry Requirements Banner


There are three requirements for entry in a GMDSS course.

The candidate must be fluent in both written and spoken English.

They must be able to use the Phonetic Alphabet.

They must be familiar with the layout of a computer keyboard and will be required to type messages into a computer system at a rate of 50 characters per minute about 1 character per second.

Certain pre-course reading is recommended. See the "Further Reading" paragraph at the bottom of this page.

Intake Limitations Banner



The number of places available on the course is limited to twelve.

The course duration is seven days with the examination taking place over most of the eighth day.

Further Reading Banner


We recommend "GMDSS: A Users Handbook" by Denise Brehaut. Published by Adlard Coles Nautical. This is a very good course manual and provides first class pre course reading.

In addition the Admiralty List of Radio Signals (ALRS) Volume 5 (GMDSS) will provide an excellent reference source to the GMDSS.
