Observability Analysis of Four-position Alignment for Laser Gyroscope Strap-down Inertial Navigation System

摘要：

In this paper, A laser gyroscope strap-down inertial navigation system (SDINS) error model with 12 system state parameters is derived, and the observability of SDINS is discussed by observability analysis of piece-wise constant system (PWCS) and observable degree analysis method based on the singular value decomposition (SVD). It is demonstrated that fourposition alignment can make the system completely observable, and all the system state parameters can be estimated by Kalman filter. The simulation indicates the efficiency of the analysis results.
