GMDSS General Operator's Certificate (GOC) Practice Exam

In GMDSS, a land earth station (LES) is the shore-based link that connects the satellite portion of the maritime distress and safety system to the land networks. Each country operates LES facilities, and the LES location names are tied to the country that owns or operates them. Yamaguchi is a city in Japan, so the LES location identified as Yamaguchi indicates Japan. The other country options would have their LES located within their own borders, not in Japan. So the country associated with Yamaguchi as an LES location is Japan.
