description An apparatus (110) comprises: a magnetic target (120) for generating a magnetic field that is uniform and concentric about a central axis of the magnetic target (120); an array (130) of three-axis digital magnetic compasses for sensing the magnetic field; and a processor (140) for finding intersection points of vectors from the compasses (210) to the magnetic target (120). The vectors lie in a global X-Y plane that is normal to the central axis. Each vector indicates a direction of sensed magnetic field from one of the compasses (210) to the magnetic target (120). 장치(110)는, 마그네틱 타겟(120)의 중심축 둘레로 동심이면서 균일한 자기장을 생성하기 위한 마그네틱 타겟(120); 자기장을 센싱하기 위한 3축 디지털 자기 나침반들의 어레이(130); 및 나침반들(210)에서부터 타겟(120)까지의 벡터들의 교차 포인트들을 알아내기 위한 프로세서(140);를 포함한다. 벡터들은 중심축에 수직인 글로벌 XY 평면 내에 존재한다. 각각의 벡터는 나침반들(210) 중의 하나에서부터 마그네틱 타겟(120)까지의 센싱된 자기장의 방향을 나타낸다.
