Disclosed are a signal transmission device for measuring a position, an indoor positioning method using the same, and a device performing the same. The indoor positioning method using the signal transmission device for measuring a position comprises: a step where air generated in an air generation means is supplied to a plurality of sound or ultrasound generation means through a discharge hole formed on an air supply means; a step where an indoor positioning apparatus receives sound and ultrasound waves, having different frequencies and generated in the sound and ultrasound means; and a step where a position of an indoor positioning reception object is measured based on the intensity and frequency of the received sound and ultrasound waves. Therefore, the indoor positioning technology can reduce the cost of constructing infrastructure for measuring an indoor location and increase the accuracy of indoor positioning. |
