This paper describes a distance measurement device for 3-dimensional indoor positioning system under the daily-life environment. By considering penetration for objects and tolerance for noises, we adopted to measure time-of-flight of spread spectrum (SS) radio at 2.4 [GHz] frequency. Since the velocity of the radio wave is about 3×108 [m/s], we utilized a high precision time measurement LSI for measuring the round-trip time of the radio wave between the measurement point and the reference point. The experimental results showed that the proportionality relation between the round-trip time and the distance was observed. By setting up three reference points in the room, 3-dimensional position measurement experiment was performed. The error of 3-dimensional position which was calculated by using the measured three distances was about 0.36 [m] . It was also confirmed that the distances could be measured if obstacles like woods or acrylic boards existed between the measured point and the reference point.
