Introduction

Based on Alice, a new generation of high-performance automotive-grade GNSS SOC chip in 22nm process from Bynav Technology, the C2 GNSS high-precision positioning and heading board has a built-in high-precision measurement engine and navigation engine, which can effectively cope with harsh environments such as satellite signal interference and loss, and quickly get the accurate relative position of dual antennas and the angle (azimuth) between the baseline of dual antennas and true north. At the same time, by receiving the differential data of the base station, real-time carrier phase differential positioning (RTK) can be realized, providing continuous, real-time, and credible high-precision position and attitude for the vehicle.
