Based on the indepth study of the positioning principle and algorithm of UWB and low cost MEMS,a UWB assisted MEMS location algorithm is proposed to suppress the divergence of MEMS and improve the positioning accuracy.The fusion location algorithm is designed and the indoor positioning technology based on MEMS/UWB is completed.Finally,within the total distance of 253.4 meters in the experiment,the MEMS positioning error is less than 0.61 meters,and the MEMS/UWB fusion positioning error is less than 0.07 met...
