This thesis provides a comprehensive investigation of the evolution of electronic instruments in maritime communication, looking back at ancient methods such as visual signals, acoustic signals and carrier pigeons. It delves into early telecommunications developments, such as the radio direction finder and gyro compass, which led to the revolutionary discovery of radar. At the same time there is an analysis of radio communication technologies, including very high, high and medium frequency bands as well as the NAVTEX system.
In addition, satellite communication systems are specified, in terms of their types, design and operation, with an emphasis on INMARSAT, and VSAT technologies. The purpose of the INMARSAT system, historical background and satellite infrastructure as well as the INMARSAT-C system are explored, alongside consideration of VSAT systems, their access to satellites and their application to maritime operations.
Finally, this thesis deals with emerging technologies and challenges in maritime communication, specifically the Starlink project and its relevance to maritime operations. It then delves into the field of Cyber Security in shipping, identifying risks and outlining preventative measures and training strategies to effectively block threats. Through this comprehensive analysis, the thesis contributes to a deeper understanding of the past, present and future of technologies developed for maritime communications and their impact on the shipping industry.
