Abstract

In order to meet requirements of three-dimensional (3D) indoor positioning in the environment with multipath interference and non-line-of-sight (NLOS) errors, this paper improves setting rules of trusted factors about ultra wide band(UWB) and the inertial navigation system(INS) to the indoor positioning algorithm, realizing confidence factors' dynamic calibration. A method to restrain NLOS errors is proposed, and the fitting method is used to smooth singular points in the track. An actual system is built to verify the improved performance of this algorithm. The actual tests show that the algorithm can effectively improve the 3 dimensional positioning accuracy, positioning error can be controlled within 20cm.
