Overview
About this product
The AMEC B620 is a Class B CS AIS transceiver built around a 72-channel multi-constellation GNSS receiver (GPS, Galileo, BeiDou, GLONASS) with 2.5m horizontal accuracy and a 30-second cold-start time to first fix. It transmits at 2 Watts (+33 dBm) using CSTDMA channel access across the 156.025 to 162.025MHz VHF band, with AIS receive sensitivity better than -111 dBm at 20% PER, and outputs data over two bi-directional NMEA 0183 ports, an NMEA 2000 connection (LEN=1) and a USB-C virtual COM port. Housed in a 151 x 129 x 50 mm, 400g enclosure, it is IP68 rated for waterproofing and dust resistance, operates from -25C to +55C, and complies with IEC 62287-1, IEC 61108-1 and IEC 60945 standards.
