Evolution of testers for GMDSS radio equipment

Category: General

The protection of human life at sea has reached a new level over the past three decades, - since 1992, the phased implementation of the GMDSS (the Global Maritime Distress and Safety System), developed by International Maritime Organization (IMO), began.
