Modeling and semi-physical simulation of in-flight alignment for MIMU under large heading error

  • The micro inertial measurement unit (MIMU) in micro unpiloted aerial vehicles initial alignment time is short, so in-flight alignment for MIMU is worked under large heading error with the global positioning system (GPS) assistant. Aimed at the requirement of high estimation precision and real time,a linear model with large heading error is introduced by regarding nonlinear vector as state vector, and adaptive Kalman filter (AKF) base on this linear model is used for MIMU in-flight alignment. The semi-physical simulation results show that this method has better precision than extended Kalman filter (EKF) with nonlinear model, and the heading error descends very quickly from 60° to around 2°. Furthermore, AKF need less computation time than EKF, only 67% of EKF.
