SNC100C-B0 integrated navigation system has high-performance MEMS gyro and accelerometer. This system can receive internal GNSS data, realize multi-sensor fusion and integrated navigation algorithm. When GNSS is invalid, the position, speed and attitude of inertial solution can be output, and certain navigation accuracy can be maintained in a short time. In the integrated navigation, it can output the original post-processing information for NovAtel's IE post-processing software.
