GMDSS is essential for maritime safety, enabling distress alerting, search and rescue coordination, and general communications. Regular surveys are mandated by IMO SOLAS regulations to verify that your radio equipment functions optimally in emergencies. Our services help prevent downtime, ensure regulatory compliance, and enhance operational efficiency. With a focus on NSR Marine’s innovative and MED-approved equipment, we offer support for systems that are robust, user-friendly, and globally certified.
