Fault Detection of Strap-down Inertial Navigation System Based on SVD
Abstract：Gyroscope is the core component of the inertial navigation system.In view of the characteristics of optical fiber gyroscope＇s signal,the Singular Value Decomposition（SVD） method was applied into the fault occurrence.The experiment proves that the SVD method can not only detect the single gyroscope fault occurrence,but also effectively detect two-gyroscope＇s simultaneous fault,which can enhance the system security.The six single-degree-of-freedom gyroscopes are studied.By reasonably arranging the detection point,the on-line detection for the state of system＇s key parts was realized.The simulation results prove that this method is feasible and can also improve the precision and reliability of the system.
