Abstract
Proposed is a position measuring device configured to measure a position (distance) by combining a TWR positioning method and a PDOA positioning method. The proposed position measuring device: outputs positioning signals at set time intervals; receives response signals for the positioning signals; measures the distance between a plurality of diversity antennas and an object on the basis of the respective positioning signals and response signals transmitted and received by the diversity antennas; and measures the distance to the object on the basis of the measurement values of the distances between the plurality of diversity antennas and the object.
