Method and apparatus for measuring position using radio communication

PURPOSE: A positioning method using wireless communication and an apparatus thereof are provided to improve accuracy of the calculated specific position. CONSTITUTION: A positioning apparatus (20) includes a checking unit (210) and a calculation unit (220). The checking unit checks a first reference position, a second reference position and a third reference position. The calculation unit calculates distance D1-D3 between the first, the second and the third reference position and a specific position by distance measurement method using wireless communication, and calculates positions of intersection points of a first, a second and a third circle constituted with points separated as distant as D1-D3 from the first, the second and the third reference position by using a trigonometric function. The checking unit calculates position of an intersection point of a first straight line passing two intersection points of the first circle and the second circle, a second straight line passing two intersection points of the second circle and the third circle, and a third straight line passing two intersection points of the first circle and the third circle from the position of the intersection points by using a straight line equation. The checking unit calculates the specific position by using the position of the first, the second and the third straight line.
