X2 Automotive-Grade Positioning Unit

X2 optimally combines high-accuracy, low bandwidth GNSS measurements with high bandwidth IMU measurements with to provide high-accuracy, low latency position, velocity, and attitude measurements.
Developed and optimized mainly for in-vehicle applications scenarios in urban canyon, especially when in complex urban environment where the satellite signal is lost, X2 can still provide continuous and uninterrupted high-precision positioning services. 

 

Highly Integrated 3-Channel Multi-Mode Multi-Frequency GNSS RFIC

Track up to 320 channels simultaneously and support BDS-3 signals.
