Inthiswork,afastandaccuratestationaryalignmentmethodforstrapdowninertialnavigationsystem(SINS)isproposed.IthasbeendemonstratedthatthestationaryalignmentofSINScanbeimprovedbyemployingthemultipositiontechnique,butthealignmenttimeoftheazimutherrorisrelativelylonger.Overhere,thetwo-positionalignmentprincipleispresented.OnthebasisofthisSINSerrormodel,afastestimationalgorithmoftheazimutherrorfortheinitialalignmentofSINSonstationarybaseisderivedfullyfromthehorizontalvelocityoutputsandtheoutputrates,andthenovelazimutherrorestimationalgorithmisusedforthetwo-positionalignment.Consequently,thespeedandaccuracyoftheSINS'sinitialalignmentisenhancedgreatly.Thecomputersimulationresultsillustratetheefficiencyofthisalignmentmethod.
