Herein, ground calibration experiments were performed to determine the sensitivity for all components and the angles (alignment) between the measurement axes of the magnetic field experiment (MGF) onboard Arase satellite. We can well determine the sensitivities within 0.07 % error and the alignment within 90 +/- 1 deg with - 0.03deg accuracy. Also, the temperature dependences of the offset and sensitivity were examined. Results revealed that the relative sensitivity to the room temperature can be fit with a linear regression line. The offsets exhibited systematical dependences on temperatures. Between March 13, 2017 and April 30, 2018, when MGF with an 8000-nT range mostly measured ambient magnetic field in orbit at -10 C-0 C, the linearity of sensitivity and offset with a standard error of less than 0.00023 and less than 0.67 nT, respectively, was determined. The measured sensitivity, alignment, and offset were used to measure the magnetic field with high accuracy, thereby meeting the MGF capability and performance requirement of the field intensity less than 5 nT and the field direction error less than 1 deg.
