1. Introduction
The Korea Meteorological Administration(KMA) has started marine weather broadcast service by GK2A satellite from 2020, which provides high-quality digital marine weather information to ships operating at sea. The KMA‘s marine weather broadcast service(MWSB) is a cutting-edge service that uses GK2A, it is the world’s only public satellite service dedicated to providing weather information free of charge with an aim of ensuring the safety of ships. Marine weather satellite broadcasting services can broadcast a lot of meteorological information such as color images, voice, and text message to ships.

Among the data provided by marine weather satellite broadcasting, marine emergency disaster information was currently provided to domestic users, but it is expanded to the Asia-Pacific region to provide marine weather information essential for maritime safety to areas with limited Internet communication as well as marine ships.
Users who wish to receive MWSB service should equip Small-scale Data Utilization Station(SDUS). If users equip SDUS, users can check MWSB service through smartphones, tablets and large monitors. SDUS specification is as follows (see Figure 2).
