M20D/M21D

GNSS/INS High-precision Positioning and Heading Module 

Based on Alice, the automotive-grade GNSS SoC from Bynav, M20D/M21D feature high-precision measurement engine, navigation engine and functional safety engine and are capable of providing consistent, real-time and reliable high-precision position and heading in hash environments of signal jamming and GNSS denial, etc.

 

Specifications and Guides

GNSS/INS Module

It is capable of providing continuous, real-time and reliable high-precision position in harsh environments where satellite signals are interfered or blocked. Featuring high integration, high performance, low power consumption and small size, the modules can be applied in automatic driving, advanced driver assistance, lane-level navigation, drones, intelligent robots, precision agriculture, surveying, mapping, etc.
