PROBLEM TO BE SOLVED: To provide a technology for highly precisely detecting an azimuth on the basis of geomagnetism.SOLUTION: A point information transmitter (20) is disposed at a predetermined location, and transmits point information containing at least magnetism correction information, which is used to correct a deflection in geomagnetism occurring at the location. A wireless positioning terminal (10) includes correction means (15) that corrects an azimuth, which is detected based on the geomagnetism by azimuth detection means (34), on the basis of the magnetism correction information contained in the point information received from the point information transmitter.SELECTED DRAWING: Figure 1
