一种磁场传感器与使用该磁场传感器的电子罗盘
摘要：
一种磁场传感器与使用该磁场传感器的电子罗盘，此磁场传感器用以传感于一第一参考坐标系上各坐标轴的磁场分量，且第一参考坐标系是与该磁场传感器相关联。其中，当磁场传感器在该第一参考坐标系上其中一坐标轴A的灵敏度不同于其他坐标轴上的灵敏度时，该坐标轴A上的磁场分量Am可用以下的方程式进行修正：Am＝Am(n-1)×(Wa-1)/Wa+Am(n)×1/Wa……(A)其中，Am(n)是指当下所量测到的沿着该坐标轴A的磁场分量，Am(n-1)是指前一次所量测或计算的沿着该坐标轴A的磁场分量，Wa则为一权重值。本发明有益效果是可取得较精确的磁场分量Am，这样一来电子罗盘便可取得较精确的俯仰角、滚转角、或偏航角。
摘要（英）：

A magnetic sensor and the electronic compass using the same are provided. The magnetic sensor is configured to sense magnetic components along each axis of a first reference coordinate system, and the first reference coordinate system is associated with the magnetic sensors. When a sensitivity of the magnetic sensor for an axis A of the first reference coordinate system is different from a sensitivity for another axis, the magnetic component Am along the axis A is corrected using the following equation: Am=Am(n-1)(Wa-1)/Wa+Am(n)1/Wa (A) Therefore, Am(n) designates a current measured magnetic component along the axis A, Am(n-1) designates a previous measured or calculated magnetic component along the axis A, and Wa is a weight value.
