High Precision Tri-axial MEMS Gyroscope Module based on Redundant Implementation and Sensor Fusion

Aiming at the typical orthogonal configuration scheme (twelve sensors are orthogonal), the project implementation. With the redundant system and small guide system Navigation computer are linked together, complement a complete micro-miniature redundant strap-down inertial navigation system. Studied the system of fault detection, fault isolation and the system reconstruction technology, and use direct comparison measurement method and the weighted least squares method respectively as the fault detection and system reconstruction project implementation plan, implement the redundant in the system of IMU data collection, fault detection, identification, isolation and system reconfiguration, solving a series of functions such as navigation parameters.
