Overview
The Beitian BE-59D is a GNSS positioning antenna/receiver with serial data output for marine, agriculture equipment, and industrial positioning applications. It uses the M10050 chip and supports multiple baud rates and NMEA/UBX output for integration with controllers, computers, and other serial host devices.
Key Features
- Multi-system combined positioning: GPS, BDS, GALILEO, SBAS, QZSS
- Serial output level: RS-232 level
- Protocols: NMEA, UBX
- Configurable update rate: 0.25Hz to 18Hz (default 1Hz)
- With FLASH (configuration can be changed)
- IP67 waterproof grade
- Magnetic bottom mounting
- Multiple connection methods available by model selection (DB9, USB, 4-wire)

Details

Select the variant that matches your host interface and supply level (DB9 RS‑232, USB, or 4‑wire TTL options).

Firmware and output settings can be adjusted for integration needs, including baud rate and NMEA/UBX output.

Multi-constellation reception (GPS/BDS/Galileo/SBAS/QZSS) supports stable positioning for marine, agriculture, and industrial use.

Serial data output is designed for direct connection to controllers, PCs, and other serial host devices.

Standard NMEA-0183 sentences (GGA, GSA, GSV, RMC, VTG and more) provide time, location, speed, and satellite details.

Test results summarize sensitivity, accuracy, start time, and low power consumption characteristics.

Physical size and key electrical specs are provided for enclosure planning and system design.

DB9 pin definitions and mechanical dimensions help confirm wiring, mounting, and cable routing before installation.

Common deployments include vessel navigation, fleet/logistics tracking, and port or yard vehicles.
