BeiDou GNSS module A40s

GLONASSGALILEOGPS

Product overview
The A40s is a compact GNSS positioning module designed for high-precision integration in industrial and mobile systems. It supports multi-constellation reception and RTK workflows to enable centimeter‑level positioning when used with correction sources.

Key features

• Multi-constellation GNSS (GPS, GLONASS, Galileo, BeiDou support)
• RTK-ready with support for correction inputs (RTCM)
• Centimeter‑level positioning in RTK mode; decimeter accuracy with SBAS/standard GNSS
• High update rate and low latency suitable for dynamic platforms
• Flexible interfaces (UART, USB, I2C, SPI — configurable)
• Compact form factor and low power consumption for OEM integration

Applications

• Surveying and geospatial equipment
• UAV / drone navigation and mapping
• Autonomous vehicles and ADAS
• Precision agriculture and machine control
