em-trak B954 Class B AIS Transceiver - 5W SOTDMA w/WiFi, Bluetooth, & VHF Antenna Splitter

The em-trak B954 Class B AIS Transceiver is a professional-grade maritime vessel tracking system designed for commercial and recreational boaters who require Coast Guard compliance and real-time position reporting. Built around Automatic Identification System (AIS) technology, this 5W SOTDMA unit broadcasts your vessel's location, course, and speed to other equipped vessels and shore-based monitoring stations, providing critical situational awareness for collision avoidance and search-and-rescue operations. Whether you operate in congested shipping lanes, coastal waters, or open ocean, this transceiver integrates essential safety intelligence directly into your navigation workflow.

The B954 employs SOTDMA (Self-Organized Time Division Multiple Access) technology to manage VHF frequency sharing, ensuring reliable transmission even in high-traffic maritime zones without interference or collision. Its 5-watt transmission power delivers adequate range for coastal operations and VHF propagation conditions. The unit features integrated WiFi and Bluetooth connectivity, allowing operators to access AIS data and vessel information remotely via compatible mobile devices and chartplotting software. The included VHF antenna splitter enables seamless integration with existing VHF radio installations, eliminating the need for dual antennas and reducing topside clutter. At just 1.8 pounds and measuring 7 x 6 x 7 inches, the compact form factor fits easily in electronics enclosures or mounting brackets aboard vessels of any size.

This transceiver is ideal for professional mariners, commercial fishing operators, and safety-conscious recreational boaters who prioritize regulatory compliance and crew protection. It benefits anyone navigating congested waterways, conducting offshore operations, or operating in areas where vessel tracking enhances emergency response capabilities. Installation requires FCC programming by a qualified technician to activate your MMSI (Maritime Mobile Service Identity) number, a mandatory step for all Class B AIS units sold in the United States. Compatible with standard marine VHF antenna systems and modern chartplotting platforms, the B954 integrates smoothly into existing vessel electronics without requiring system overhauls.
