It integrates SOTDMA 5W technology and a VHF antenna splitter, providing an advanced communication solution for various navigation setups.\n\u003c\/p\u003e\n\n\u003ch3\u003eAIS SOTDMA 5W technology\u003c\/h3\u003e\n\u003cp\u003e\n    The B953 uses SOTDMA (Self-Organising Time Division Multiple Access) technology with a 5W transmit power. This 37dBm ± 1.5 dB output power ensures transmission priority on AIS channels, extended range, and more frequent position updates compared to CSTDMA Class B transponders. The transponder operates on a frequency range of 156.025 to 162.025 MHz in 25 kHz increments, with a 25 kHz channel bandwidth and 25 kHz GMSK modulation modes (AIS, TX and RX). The data rate is 9600 b\/s ± 50 ppm (GMSK), and the receiver sensitivity is better than -107 dBm at 20 % PER.\n\u003c\/p\u003e\n\n\u003ch3\u003eGPS receiver and connectivity\u003c\/h3\u003e\n\u003cp\u003e\n    This transponder includes a 72-channel GPS receiver compliant with IEC 61108-1, compatible with L1 GPS (1575.42 MHz), L1 GLONASS (1597.1–1609.5 MHz), E1 Galileo (1575.42 MHz), and B1 BeiDou (1561.098 MHz) bands. For integration with navigation systems, the B953 features multiple interfaces: NMEA 2000 (LEN=1), two NMEA 0183 ports (one high-speed at 38,400 baud and one low-speed at 4,800 baud), and a USB port. It includes an integrated VHF antenna splitter, allowing a single VHF antenna to be used for both AIS and VHF radio.\n\u003c\/p\u003e\n\n\u003ch3\u003eDesign and technical specifications\u003c\/h3\u003e\n\u003cp\u003e\n    The B953 is designed to withstand marine environments, with IPx6 and IPx7 ratings making it resistant to water and weather. It operates within a temperature range of -25°C to +55°C. Its dimensions are 149 x 118 x 47 mm (L x W x H), and it weighs 345 g. The device is powered by a 12 to 24V DC supply (9.6–31.2V maximum), with an average power consumption of 245 mA \/ 2.95 W at 12V and a peak current of 2.5 A. Installation is simplified with an included FLEXI-FIT mount, and configuration can be performed via PC using the proAIS2 tool.\n\u003c\/p\u003e","brand":"EM-Trak","offers":[{"title":"Default Title","offer_id":57646072693076,"sku":"MCT-EMTR-B953","price":824.5,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0988\/3274\/4788\/files\/df1u2hlw_MCT-EMTR-B953-MCT-EMTR-B953-official.png?v=1792143888","url":"https:\/\/skysat.fr\/en-bh\/products\/em-trak-b953-transpondeur-ais-classe-b-sotdma-5w-splitter","provider":"Skysat","version":"1.0","type":"link"}
