| Summary: | 碩士 === 國立中央大學 === 光機電工程研究所 === 99 === 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.
