PROBLEM TO BE SOLVED: To improve positioning accuracy by performing correction corresponding to a radio wave propagation environment without providing a new wireless apparatus separately. SOLUTION: This system has moving stations 10A-D related to employees P1-4, a plurality of base stations 12A-D, and a positioning server 14 for performing positioning processing of the moving station 10. The positioning server 14 calculates a correction value for correcting a positioning processing result corresponding to accumulation with time of position data of the moving stations 10A-D by the positioning processing, and after calculation of the correction value, corrects position data of a newly-positioned moving station 10A-D based on the correction value.
