Today, the world is more connected than ever before, in part with help from commu-nication satellites. Usage of these systems is very simple, but to provide quality service from low Earth orbit several factors need to be considered. In this paper the addressed problems are focused on establishing and forwarding links between satellites and towards users, thus explaining problems of satellite network realization. Referring to use of satellite networks in maritime affairs, possibilities for new systems are created and further more increase usability of existing ones as well as improving the logistics chain. The paper briefly describes the problems that arise when establishing satellite connection while pos-sible solutions are listed. Furthermore, it is important to note that these solutions use avail-able resources and technology at the time they were envisaged; culminating with newest solution in last segment. In the end examples of existing and developing networks are II listed together with an example of satellite AIS that, with assistance from communication satellites, could greatly enhance maritime affairs. In conclusion examples of possible uses of system in maritime traffic are given most of which is left to the reader’s imagination.
