Application Of A New Type Of Linear Vibration Table To InsPlatform Drift Error Model Parameter Separation

摘要

A new type of linear vibrationrntable is brought forward, whose applicationrnto INS error model parameter separation isrninvestigated. The application of the ExtendedrnKalman Filter(EKF) to identify INS platformrndrift error coefficients under the condition ofrnideal and nonideal linear vibration isrnpresented. And a multi-position testingrnscheme is designed which can obtainrnsatisfying estimation results as the amplitudernof linear vibration is constrained.
