It features a powerful 5W SOTDMA transmission, enabling you to detect and be detected by more AIS targets at maximum range while maintaining low power consumption. Its integrated VHF antenna splitter allows seamless sharing of your existing VHF antenna without any performance loss, making installation straightforward and efficient. The built-in GPS receiver provides accurate positioning data, with support for multiple GNSS systems including GPS, GLONASS, BeiDou, and Galileo, ensuring quick and precise location fixes even from a cold start in approximately 26 seconds. This device complies with international standards such as IEC 62287-2 and ITU-R M.1371.5, and is certified for use in the US, Canada, and Europe, including US Coast Guard requirements. Its rugged IPx6 and IPx7 ratings guarantee water, pressure spray, and damp proof performance, suitable for challenging marine environments. The B953’s design features a FLEXI-FIT bracket system for easy installation, protected against vibration, shock, and extreme temperatures, making it ideal for a variety of vessel types. Connectivity options include NMEA 0183, NMEA 2000, and USB interfaces, providing seamless integration with chart plotters and PC systems for real-time data sharing and monitoring. The transceiver also incorporates intelligent health and performance monitoring, a silent mode for transmit-off operation, and built-in surge protection for enhanced reliability. Its small footprint and low power consumption make it suitable for space-constrained installations, while its multiple data interfaces ensure compatibility with existing marine electronics. The package includes the transceiver, power and data cable, accessory cable, FLEXI-FIT mounting bracket, screws, and optional fixing tape. Whether outfitting a commercial vessel or a recreational boat, the em-trak B953 delivers high-performance AIS capabilities with easy installation and reliable operation in demanding marine conditions.\u003c\/p\u003e\u003cp\u003e\u003cb\u003eFeatures:\u003c\/b\u003e\u003c\/p\u003e\u003cul\u003e\u003cli\u003eCertified AIS Class B 5W SOTDMA for reliable vessel identification\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eIntegrated VHF antenna splitter for seamless antenna sharing\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eGlobal certification including USCG, FCC, Canada, and Europe standards\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eAdvanced SRT-AIS transceiver engine for superior performance\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eFLEXI-FIT bracket system for quick and secure mounting\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eBuilt-in high-performance GPS receiver supporting multiple GNSS systems\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eRugged IPx6 and IPx7 waterproof design for marine environments\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eCompact and lightweight construction for space-saving installation\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eUltra-low power consumption for efficient operation\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eGuaranteed interoperability with chart plotters and PCs via NMEA 0183, NMEA 2000, and USB\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eAutomated health and performance monitoring\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eSilent mode (transmit-off) for versatile operation\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eEnhanced RF shielding against electromagnetic interference\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eBuilt-in surge protection for electrical safety\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eFail-safe VHF radio operation ensuring continuous connectivity\u003c\/li\u003e\u003c\/ul\u003e","brand":"em-trak","offers":[{"title":"Default Title","offer_id":44441300140074,"sku":"98707","price":946.44,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0692\/2285\/8794\/files\/98707XL.jpg?v=1780939230","url":"https:\/\/atticusgoods.com\/products\/em-trak-b953-class-b-ais-transceiver-with-5w-sotdma-and-vhf-antenna-splitter","provider":"Atticus Goods","version":"1.0","type":"link"}
