Due to the poor bias repeatability and large random noise of a micro electro mechanical system (MEMS). the Allan variance was used to analyze the random angle walk of MEMS. The information fusion algorithm of array gyro was designed by using Allan variance identification value and weighted least square method. which could effectively reduce the random angle walk and respond to the tru... https://allfixelectricales.shop/product-category/lighter-socket-power-adaptor/
