Research on the error self-correction of MEMS inertial navigation system

SUN Wei;DING Wei;XU Aigong;YAN Huifang;LI Ruibao;School of Geomatics,Liaoning Technical University;  
According to the current MEMS inertial devices' large drift error,the error self-compensation method without any other suggestions was proposed in this paper.The rotating modulation technology was used to average the device bias.The error characteristics of scale factor and installation were analyzed.The practical performance of error self-correct method was verified on high precision test turntable.Experimental results show effectiveness of error rotating modulation to improve the navigation precision of MEMS inertial system.This research can provide theory study and engineering application reference for independent work of MEMS inertial navigation system.
