Ships using the US Federal Communications Commission (FCC) as an Inmarsat accounting authority will be obliged to find an alternative after The FCC released a Public Notice announcing a transition and outreach plan to facilitate its withdrawal as an accounting authority in the United States in the maritime mobile and maritime mobile satellite services.
Customers currently subscribed to US01 must select a new accounting authority. The FCC announced that it will stop performing the functions of an accounting authority for international maritime mobile communications on April 22, 2020. Users who have relied on the FCC as an accounting authority need to affirmatively select a different accounting authority prior to that date.
Those using Inmarsat-C terminals under the Global Maritime Distress and Safety System (GMDSS), Long Range Identification and Tracking, and Ship Security and Alert System that have selected AAIC US01 when the terminal was commissioned will be affected by this change. Such terminals attempting to transmit after this date will immediately become barred. Affected GMDSS terminals will still be capable of transmitting a distress alert.
Those affected by the decision are advised to visit the International Telecommunication Union’s website https://www.itu.int/mmsapp/AccountingAuthority/list for available alternative accounting authorities.
