The estimation unit 32 estimates, from second time-series data, a state of the radio field intensity at a position of an apparatus 20. An estimation unit 33 estimates a state of the radio field intensity at each point in a target space by using the position of each apparatus 10 and the state of the radio field intensity thereof. An estimation unit 34 compares the state at each point with the state at the position of the apparatus 20 and thereby estimates the position of the apparatus 20. An estimation unit 35 estimates a position state of the apparatus 20 based on time-series data of the position of the apparatus 20.
