Kind Code:
A1
Abstract:
[Problem] To provide a position measurement device capable of accurately detecting the position of a target within a wide measurement area. [Solution] A mobile station M is moved close to a mobile terminal 20 that is a target. In ST1, the absolute position of the mobile station M within absolute coordinates (Abs) set in a measurement area is calculated. In ST2, the relative position of the mobile terminal 20 within relative coordinates (Rel) set by the mobile station M is detected. In ST3, the orientation of the mobile station M in the absolute coordinates (Abs) is detected. In ST4, the relative coordinates (Rel) are rotated. In ST5, the absolute position of the mobile terminal 20 in the absolute coordinates (Abs) is specified.
