It uses SOTDMA (Self-Organising Time Division Multiple Access) technology with a 5W transmission power, offering improved range and reliability compared to 2W CSTDMA Class B transponders, ensuring your position is clearly visible to other vessels and coastal stations.\u003c\/p\u003e\n\n\u003ch3\u003eConnectivity and System Integration\u003c\/h3\u003e\n\u003cp\u003eThe B954 stands out for its extended connectivity, integrating Wi-Fi, Bluetooth, and a VHF antenna splitter. It features NMEA 0183 interfaces (two ports, one high-speed at 38,400 baud and one low-speed at 4,800 baud), NMEA 2000, and USB, enabling seamless interconnection with all modern navigation equipment, from chartplotters to mobile applications. All converted NMEA PGNs are multiplexed to all NMEA 0183, USB, Wi-Fi, and Bluetooth outputs.\u003c\/p\u003e\n\n\u003ch3\u003eGPS and VHF Performance\u003c\/h3\u003e\n\u003cp\u003eThis transponder is equipped with a 72-channel integrated GPS receiver compliant with IEC 61108-1, compatible with L1 GPS (1575.42 MHz), GLONASS (1597.1–1609.5 MHz), Galileo (1575.42 MHz), and BeiDou (1561.098 MHz) bands, ensuring rapid acquisition and precise positioning. Its VHF transceiver includes one transmitter and two receivers (shared between AIS and DSC) operating on frequencies from 156.025 to 162.025 MHz in 25 kHz increments. The SOTDMA output power is 37 dBm ± 1.5 dB.\u003c\/p\u003e\n\n\u003ch3\u003eRobust Design and Technical Specifications\u003c\/h3\u003e\n\u003cp\u003eThe B954 is designed to withstand the most demanding marine environments, being water- and weather-resistant (certified IPx6 and IPx7). Its compact dimensions of 149 x 118 x 47 mm (Length x Width x Height) and weight of 345 g (for models with integrated splitter) facilitate installation. It operates on a DC 12–24 V input voltage (9.6–31.2 V maximum) with an average power consumption of 280 mA \/ 3.35 W at 12 V and a peak current of 2.5 A. The operating temperature range is from -25°C to +55°C.\u003c\/p\u003e","brand":"EM-Trak","offers":[{"title":"Default Title","offer_id":57648361341268,"sku":"MCT-EMTR-B954","price":1375.07,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0988\/3274\/4788\/files\/1073ky27_MCT-EMTR-B954-MCT-EMTR-B954-official.png?v=1792155473","url":"https:\/\/skysat.fr\/en\/products\/em-trak-b954-transpondeur-ais-classe-b-sotdma-5w-wifi-bluetooth-splitter","provider":"Skysat","version":"1.0","type":"link"}
