This Commonwealth of Dominica approved course allows you to complete your GMDSS Radio Operator course online! NEMO°’s GMDSS Radio Operator Course combines online simulations, animations, helpful explanations, quizzes and final exam to make your training experience engaging and comprehensive. You will explore the functionality and use of all GMDSS components ranging from daily communication to emergency situations using our suite of HALO° simulators. All text passages include an audio component to assist ESL students. Upon completion of the course, you will have access to your course completion certificate as a record of your training.

This course covers required training and competences in Table A-IV/2 of the STCW Code for GMDSS Radio Operators.

Upon successful completion of this course and passing the prescribed examination, a trainee should be able to:

  1. Efficiently operate GMDSS equipment required in sea area A1, A2, A3,  and A4.
  2. Fulfill primary radio communications responsibility during distress, urgency, safety and routine incidents.

Given the number of serious problems experienced in the GMDSS resulting from numerous, often accidental, false distress alerts, training will be provided to ensure the awareness and avoidance of unintentional transmission of false distress alerts, and the procedures which mitigate the effects of false distress alerts following unintentional transmission.



  • All exams can be taken online through HALO° Exams. You will receive 3 attempts for your exam. If you fail all 3 attempts, you must pay a retake fee of $50.00.

This fully online course can be taken at your own pace.  Recommended equipment outside of any required materials identified in the course:  computer and web camera.
