| Abstract: | In order to achieve aircraft in-flight alignment(IFA) with large heading error,a linear error model with large heading error is developed.The linear error model with large heading error is derived in detail,and the Kalman Filter model was designed.Digital simulation results indicate that the leaner large heading angle error model,which is applied in aircraft IFA,is effective for large heading angle error.The aircraft maneuver schemes for large heading angle error are suggested,and several engineering advices are given in the end. |
