本研究開發一個能讓衛星在地面上,模擬太空中磁場變化的磁場模擬艙。磁場模擬艙,要能抵銷機構誤差所造成的雜訊,還能抵抗外來環境磁場變化所帶來的干擾。模擬衛星磁場歷程部分,.要能自行設定軌道並取得該軌道磁場歷程。此外,雖然模擬艙內衛星為固定,亦要盡可能模擬衛星在太空中各種可能的姿態,以期重製磁場的旋轉等變化,令模擬磁場環境能更貼近真實的太空磁場變化。;This study is to develop a magnetic field simulator,which satellites can measure the Earth magnetic field in space.This simulator can not only eliminate the noise caused by the mechancal error but also resist the disturbances caused by the space environment field. When a code is written to acquire the magnetic field data along the orbit, it should output giving a Satellite magnetic field data along the Satellite path.Although the satellite is physically in the simulator,the magntic field of various satellite atitudes in space should be simulated
