Which CES should a GMDSS Radio Operator select if his/her vessel is off the Pacific Coast of the United States?

Correct Answer: Option C — Santa Paula

Coast Earth Stations (CES) act as the gateway between the satellite and the terrestrial network. For vessels operating in the Pacific Ocean Region, the Santa Paula CES in California is the designated station for routing Inmarsat-C traffic, ensuring efficient connectivity to the public switched network for US-based maritime operations.
