X1 Series

GNSS/INS Combined Navigation System

X1 is a combination of the GNSS high-precision board and IMU with support for dual-antenna high-precision positioning and heading. It is optimized for automotive applications, capable of dealing with such scenarios where satellite signals are interfered or blocked, so it can provide stable, continuous and reliable high-precision position and attitudes for smart cars.
