Improved performance of a low-cost PDR system through sensor calibration and analysis

This paper proposes improvement for performance of a low-cost Pedestrian Dead-Reckoning(PDR) System through calibration and analysis of sensor. It is applied that PDR System for estimating pedestrian´s position in the area not being able to be received. also sensor´s error is removed by using angle compensation technique and performance of system is improved by analysis of PDR system. Consequently, position of pedestrian is estimated by applying the improved value of sensor and result of angle analysis to PDR system. Experiments were conducted to verify the proposed system. Experimental results within 2% of range error, RMS position error of less than 3% showed superior performance.
