Beitian BE-27D GNSS Mushroom Receiver RS-232 DB9 Marine

Overview

The Beitian BE-27D GNSS receiver module is a multi-constellation, single-frequency GNSS mushroom head receiver designed for marine positioning and other navigation equipment. It integrates an antenna module and uses the M10050 chip, supporting GPS L1 C/A, BDS B1I/B1C, Galileo E1B/C, QZSS L1 C/A, and SBAS L1 C/A (WAAS, EGNOS, MSAS, GAGAN). Data output is provided via an RS-232 serial interface and supports NMEA and UBX protocols.
