Abstract
A position measuring system includes s server and radio wave emitting stations positioned at different locations across a position measuring area. A storage device stores, for each of the plurality of radio wave emitting stations, a beacon identifier that uniquely identifies the radio wave emitting station and a first threshold time. A processor receives, from a portable device, reception information including a reception time indicating when the portable device received a signal from one of the radio wave emitting stations. The processor determines, based on the received signal strength identifier, a position of the reception station in the position measuring area. The processor determines an operation state of the radio wave emitting station corresponding to the received signal. A display device displays information indicating the determined operation state of each of the plurality of radio wave emitting stations.
