This paper proposes an indoor positioning method using geomagnetic field with less spatial movement and discusses its positioning performance. In the proposed method, the user holds a geomagnetic sensor, which is often mounted on common smartphones, with his/her arm extended and turns around 360 degrees at his/her current position without walking which is required for traditional methods. The obtained sequence of change in geomagnetic field is used for acquiring the current position. A series of experiments is conducted on positioning accuracy and the results show that the proposed method works with a positioning error of 3.4 m on average and it also demonstrates the best CDF with the positioning error less than about 1.3 m.
