基于磁阻传感器的地磁数据采集装置

摘要

Traditional attitude measurement method applies gyro,accelerometer or combined with GPS to acquire data of carrier parameters,but due to high cost,limitation of precision and structure level of device,it can't meet the complex operational environment now.Put forward using 3-axis magnetic resistance sensor to collect the three-dimensional magnetic field strength of the earth,and through amplifying,processing,eventually get ideal geomagnetic data.Through experimental test,ideal geomagnetic signal can be by achieved acquisition device.%传统的姿态测量方法一般应用陀螺、加速度计或者与GPS组合对载体参数进行数据采集,但是由于成本高、器件精度与结构水平的限制,现在已经无法满足现在复杂的作战环境.提出应用三维磁阻传感器采集地球磁场三维磁场强度,然后经过放大、处理,最终得到理想的地磁数据.经过实验测试,采集装置能够获得理想的地磁信号.
