Abstract. This paper looks at the retrospective aspects of the technological development of maritime communications. It focuses on marine satellite applications and emphasizes modern demand for high speeds and broad bandwidth. Much of the current maritime communication systems are largely based on previous generations of ship-to-shore radios and have a relatively narrow bandwidth for digital communications and communications. The cost of bandwidth for satellite networks is still high due to the cost of decommissioning satellites as well as the stabilizers d for existing onboard antennas. On the other hand, the hereditary radio system uses low bandwidth and is unable to support applications requiring high data rates. Unlike terrestrial networks, advances in marine networks are lagging behind ground. As technology advances and the latest generation of Inmarsat, Iridium and VSAT satellites, the use of mobile apps and devices on board vessels as well as onshore is becoming more and more accessible
