Maritime Communications

In this document, the Federal Communications Commission (Commission or FCC) adopts additional measures for domestic implementation of Automatic Identification Systems (AIS), an advanced marine vessel tracking and navigation technology that can significantly enhance our Nation's homeland security as well as maritime safety. Specifically, in the Second Report and Order in WT Docket No. 04-344, the Commission designates maritime VHF Channel 87B (161.975 MHz) for exclusive AIS use throughout the Nation, while providing a replacement channel for those geographic licensees that are currently authorized to use Channel 87B in an inland VHF Public Coast (VPC) service area (VPCSA); determines that only Federal Government (Federal) entities should have authority to operate AIS base stations, obviating any present need for the Commission to adopt licensing, operational, or equipment certification rules for such stations; and requires that Class B AIS shipborne devices--which have somewhat reduced functionality vis-[agrave]-vis the Class A devices that are carried by vessels required by law to carry AIS equipment, and are intended primarily for voluntary carriage by recreational and other non- compulsory vessels--comply with the international standard for such equipment, while also mandating additional safeguards to better ensure the accuracy of AIS data transmitted from Class B devices. These measures will facilitate the establishment of an efficient and effective domestic AIS network, and will optimize the navigational and homeland security benefits that AIS offers.
