[PEM16-P05] Ground calibration experiments of Magnetic field experiment on the ERG satellite
Keywords:ERG satellite, Magnetic Filed experiment
We have been performed in order to determine the sensitivity and alignment via ground calibration experiments. From response of MGF-S to known applied magnetic field, we determined the sensitivity of each axis and found that the error of the sensitivity is less than 0.06%. The axis of the sensor is orthogonal to each other within 0.95 degrees. The estimated error of alignment is within 0.07 degrees. We also have examined the temperature dependence of the sensitivity and offset. The sensitivities relative to the room temperature have linearity with the standard error less than 0.0016, while the offset of the sensors have no clear linearity but reproducibility against temperature. From these ground examinations, the determination accuracies of the amplitude and direction of the magnetic field observed by the MGF will satisfy the science requirements for the Arase observations. In this presentation, we will also evaluate and show measurement error of MGF-S along the Arase orbit.
