The Global Maritime distress and Safety System (GMDSS) is becoming the all-embracing term for communication and data transfer between ship and shore, and ship and ship. It's a highly automated system of terrestrial satellite communications technology whose primary role is to maintain safety of life at sea. Within the next five years all vessels over 300 tonnes will be required to carry GMDSS equipment. The seafaring nations of the world have together established the rules and regulations for good working practices within the system, and every serving and future navigating officer will be required to hold the GMDSS General Operator's Certificate. GMDSS for Navigators brings together in one publication the knowledge required by anyone who wants to become a qualified and competent operator of GMDSS communications equipment. It should prove to be the accepted universal reference for GMDSS training.In series connection, the voltages add up arithmetically ie. two 12 volt batteries in series give an output of 24 volts. 2) Parallel connection, when positive is connected to positive, and negative to negative.
