Abstract: With the popularization and development of advanced driver assistance system (ADAS) related applications such as vehicle-to-everything, the role of automotive high-precision positioning systems has become increasingly critical. Only by ensuring the accuracy of vehicle positioning can we ensure the accuracy of many ADAS and intelligent driving related scenarios. This paper proposes a complete end-of-line testing scheme for the current mainstream automotive highprecision positioning system, which can cover the core functions of the system (real time kinematic and inertial navigation system) while checking its potential problems in time, thereby effectively improving the reliability of the automotive high-precision positioning system after mass production.
