All ships make good use of the satellite transportation system to communicate external as well as internal data understanding on the sea. At that time, there is diverse kinds of information to communicate one another such as voice, letter, picture and video on the sea to sea, sea to ground. In addition, there are other means to share information like a sign, voice, message, picture and video shared between vessels and ground units. Although the ships utilized FDMA in the initial stage of the satellite procurement, MF/TDMA method is recently applied as means to transmit information. Both FDMA and MF/TDMA, however, are not the best means of data transmission as the number of bandwidth is limited for both methods. Thus, in order to provide a solution for this problem and to see how the amount of transmission increases, a research on applying MF-TDMA + SCPC has been conducted for the Navy’s satellite communication system for the efficiency of the satellite network within the original frequency bandwidth will be maximized through the application of digital transformation methods and Roll OFF Factor as a means of data transmission.
