AIS Transponder · Navigation & Bridge Equipment
Em-trak B954 is a Automatic Identification System transponder. It is normally installed on the bridge with interfaces to GNSS, heading, speed and other navigation sensors and with dedicated VHF antennas. Its primary purpose is to transmit and receive vessel identity, position, course, speed and voyage-related data for traffic awareness and regulatory reporting. Compared with ordinary VHF radio, AIS exchanges structured digital navigation data automatically and depends on several external sensor and data interfaces. For exact ratings, dimensions, settings, materials, connection details, and variant-specific limits, refer to the manufacturer documentation for the exact figure.
What our service work and the manufacturer documentation say about keeping this model running.
Verify own-ship static and voyage data, sensor inputs, antenna condition, alarms and target reception. Compare transmitted information with approved vessel particulars and bridge sensors. Check interfaces to ECDIS, radar or pilot plugs where fitted. Radio performance testing and configuration changes must follow approved service procedures.
Carry fuses, approved power-supply parts, antenna connectors, interface cables and selected display or control components as supported by the manufacturer; maintain current configuration and vessel-data records.
