摘要:	本研究開發設計一個低成本，可程式，高解析，具有高便利性的個人電腦人機介面。磁力校正艙提供閉迴路/開迴路、固定磁場或模擬飛試動態變化之磁場以供磁力計校正使用。本論文提供此一磁力校正艙的機構設計，電路設計，以及軟體設計。同時也提供實測靜態及動態測試數據、實際驗證。本磁力艙解析度可達到0.19nT、動態範圍涵蓋±100000nT、線性度偏差0.005%、磁場設定的變化率可達100Hz、磁場設定調整之後所需的穩定時間為1m sec。 This research developed a magnetic calibration chamber which is low-cost, high-resolution, easy to use, and with PC-Based Human-machine interface(HMI). Magnetic calibration chamber provides closed loop / open loop, fixed magnetic field or in-flight scenario simulation of the magnetic field for magnetometer calibration. This thesis provides such a magnetic calibration chamber mechanical design, circuit design and software design. It also provides experimental static and dynamic test data and actual verification. The performance of the system is resolution of 0.19nT、dynamic range of ±100000nT with linearity deviation of 0.005%、the maximum update rate of the magnetic field setting 100Hz of magnetic field change、 the settling time 1m sec of magnetic field setting change.
