As one of the objectives for China’s First Mars Exploration Mission (CMM-1), the magnetic field in Mars’ near space will be measured by the Magnetometer onboard of the Orbiter (MAG-O), which consists of two fluxgate sensors and one electronic box. We conducted pre-flight calibration test to determine the temperature dependent offset and the correction matrix, which composed of sensitivities and non-orthogonality parameters. Two sets of ground validation experiments were also executed under limited condition to confirm the consistency and mutual interference of the two sensors, respectively. The results show that MAG-O meets the requirements of CMM-1 mission. This paper will introduce the procedure and results of pre-flight calibration and validation test.
