Abstract
A position detecting system includes receivers and a control unit. The four receivers are attached at positions different from one another in the circumferential direction of a pillar extending in the vertical direction. Each of first areas, which expands in the circumferential direction of the pillar, is an area in which the corresponding three receivers among the receivers receive radio waves from a transmitter directly, and is an area in which the remaining one receiver does not receive radio waves from the transmitter directly. Each of second areas is an area in which the corresponding two receivers among the receivers receive radio waves from the transmitter directly, and is an area in which the remaining two receivers do not receive radio waves from the transmitter directly. The control unit calculates the position of the transmitter by using different position computational algorithms for the first areas and the second areas.
