Abstract: Currently,theresearchandapplicationhasbeenquitematureonrotatingmodulationtechnologyofnavigationbasedonhighprecisiongyroscope.TherotatingmodulationtechnologywasintroducedtorealizehighprecisionapplicationofthelowprecisionMEMSgyroscope.Accordingtothetheoreticalanalysisandsimulationofnavigationerrorwithrotatingmodulationornot,theeffectsondifferentprecisiongyroscopewerecomparedunderthesamecondition.Aswell,thefactorsthatinfluencedthemodulationresultwasanalyzedindetail.Itturnsoutthat,comparedtohighprecisiongyroscope,therotationmodulationeffectoflowprecisionMEMSgyroscopeismoreobviousinthesamecondition,andmorethan30%navigationerrorisreducedinthe100sduetorotation.Inaddition,developinghighprecisionrotatingmodulationturntableisalsooneofthekeytechnologiesofimprovingtheaccuracyoftheMEMSgyroscoperotationmodulation.
Key words: rotatingmodulation, MEMSgyroscope, modulationturntable, navigationerror, modulationrateerror
