How do you monitor and evaluate the performance and reliability of GMDSS equipment and networks?

1 Check the functionality of GMDSS equipment

Before you start a voyage, you should check the functionality of all GMDSS equipment on board, such as VHF, MF/HF, and satellite radios, EPIRBs, SARTs, NAVTEX, and INMARSAT terminals. You should also ensure that you have adequate power supply, backup batteries, and antennas for each device. You should follow the manufacturer's instructions and maintenance guidelines for each equipment, and report any defects or malfunctions to the appropriate authorities. You should also keep a log of all tests and inspections of GMDSS equipment.

2 Monitor the GMDSS networks

During your voyage, you should monitor the GMDSS networks that are relevant to your area of operation and the type of communication you need. You should select the appropriate frequency or channel for each network, and adjust the power and modulation settings as needed. You should also avoid interference and congestion on the networks, and respect the priority and protocol of different types of messages. You should keep a log of all messages sent and received on the GMDSS networks.

3 Coordinate with MRCCs and MRCs

In case of an emergency or a situation that requires assistance, you should coordinate with the nearest MRCC or MRC, depending on the nature and location of the incident. You should follow the standard procedures for sending distress, urgency, or safety messages, and provide accurate and relevant information about your vessel, position, situation, and assistance required. You should also acknowledge and comply with any instructions or requests from the MRCC or MRC, and keep them updated on the status of the incident. You should also cooperate with other vessels or stations that are involved in the search and rescue operation.

4 Evaluate the performance and reliability of GMDSS equipment and networks

After your voyage, you should evaluate the performance and reliability of GMDSS equipment and networks, and identify any issues or problems that occurred during the voyage. You should review the logs of GMDSS equipment tests, inspections, messages, and incidents, and analyze the data for any trends, patterns, or anomalies. You should also solicit feedback from other GMDSS operators, MRCCs, MRCs, and authorities on the quality and effectiveness of your communication. You should then report any findings or recommendations for improvement to the relevant parties, and implement any corrective actions or preventive measures as needed.
