The SNC100C-BO integrated navigation system is equipped with high-performance MEMS gyroscopes and accelerometers, capable of receiving internal GNSS data to achieve multi-sensor fusion and integrated navigation calculation algorithms. When GNSS is unavailable, it outputs inertial calculated position, speed, and heading information, maintaining a certain level of navigation accuracy for a short period. During integrated navigation, it can output raw data for post-processing by NovAtel's IE post-processing software.
