em-trak B200 Class B AIS Transceiver - 5W SOTDMA w/Battery Backup

The em-trak B200 Class B AIS Transceiver is a 5W SOTDMA vessel monitoring system designed to meet FCC requirements for automatic identification and safety reporting on the water. Unlike Class A systems, the B200 delivers essential AIS functionality at a power level suitable for recreational vessels, fishing boats, and smaller commercial operations where full Class A installation is unnecessary. The integrated battery backup ensures continuous operation during shore power loss, a critical safety feature for extended periods at anchor or during emergency situations.

The 5-watt SOTDMA (Self-Organized Time Division Multiple Access) architecture provides reliable position and voyage data transmission across VHF marine frequencies without requiring external time synchronization. Battery backup maintains core AIS functionality when primary vessel power is compromised, extending operational safety margins during emergencies or remote anchorages. Compact dimensions and light weight make integration straightforward on vessels where space and weight distribution matter—critical considerations for fishing boats, research vessels, and commercial transport operations operating in regulated waters where AIS carriage is mandated or strongly recommended.

The B200 is engineered for operators who require verified AIS transmission compliance without the cost and complexity of larger Class A systems. Recreational and commercial vessel operators, fishing fleet managers, and maritime safety professionals rely on Class B transceivers to maintain situational awareness in congested shipping lanes, coastal waters, and international zones where vessel identification reduces collision risk and improves rescue response times. FCC programming is required at purchase—units must be configured by a qualified technician with valid MMSI registration or FCC Ship Station License to ensure legal operation and proper network integration.
