摘要： There are provided a method and apparatus for determining a geomagnetic field by using a compass and a method and apparatus for determining an azimuth angle of a moving object using the method and apparatus for determining a geomagnetic field. The method of determining a geomagnetic field by using a compass includes defining an allowable magnetic field range used to determine a valid geomagnetic region; calculating a magnitude of a magnetic field in a geomagnetic-field validity test region by using a compass; and if the magnitude of the magnetic field is within the allowable magnetic field range, determining that the geomagnetic-field validity test region is the valid geomagnetic region, and if not, determining that there is applied an external magnetic field disturbance. Accordingly, since an error of an azimuth angle of the compass due to an external magnetic field disturbance can be determined, it is possible to accurately detect a valid azimuth angle of the compass. In addition, since an allowable magnetic field range is determined based on a variation of magnetic field detected by a compass rather than a conventional method that simply compares a magnetic field and a geomagnetic field, it is possible to accurately determine the geomagnetic field.
摘要翻译：提供了一种使用罗盘确定地磁场的方法和装置，以及使用用于确定地磁场的方法和装置来确定运动物体的方位角的方法和装置。通过使用罗盘确定地磁场的方法包括定义用于确定有效地磁区域的允许磁场范围; 通过使用罗盘计算地磁场有效性测试区域的磁场强度; 并且如果磁场的大小在允许的磁场范围内，则确定地磁场有效性测试区域是有效的地磁区域，如果不是，则确定施加了外部磁场干扰。因此，由于可以确定由于外部磁场扰动引起的罗盘的方位角的误差，因此能够精确地检测出罗盘的有效的方位角。此外，由于根据由罗盘检测的磁场的变化来确定容许磁场范围，而不是简单地比较磁场和地磁场的常规方法，因此可以精确地确定地磁场。

摘要： A differential solenoidal magnetic field sensing device is a magnetic field sensor fabricated on a microscopic scale and is constructed by two soft magnetic film cores laminated on a semiconductor substrate, an excitation of the soft magnetic film cores, and a magnetic flux variation detecting coil formed of a spirally wound metal film pattern. Since two soft magnetic film cores constitutes closed magnetic paths, leakage of magnetic flux can be minimized. Also, the magnetic sensing device is a differential type sensor, the combination of driving signals can be offset. That is to say, the magnetic field sensing device is constructed such that two soft magnetic film cores are laminated and are formed lengthwise in the direction of a detection axis to reduce anti-magnetic field components, and the excitation coil wound around the two soft magnetic film cores and the magnetic flux variation detecting coil for obtaining the sum of magnetic flux variations generated in the soft magnetic film cores are alternately wound turn by turn around the soft magnetic film cores.
