BepiColombo MPO-MAG Calibrated Data

This collection contains calibrated magnetic field vector data and housekeeping data obtained by the MPO-MAG magnetometer aboard the BepiColombo MPO s/c. All field values are ground calibrated data in nanotesla and all housekeeping data are transformed to physical units. Files are separated by mission phases, housekeeping and science data, and sensors. The magnetic field is given in unit reference frame (urf), spacecraft coordinates (scf), or indicated celestial coordinates (e.g. ECLIPJ2000: e2k). These data were calculated using the results of the ground calibration only. This means that temperature dependent sensitivities, misalignment, and offsets of the instrument are taken into account. However, all s/c effects like time dependent disturbances by the s/c magnetic field are not eliminated yet. Only a stepwise constant estimate of the s/c field is subtracted using the static_offset calibration files. For proper scientific research derived data should be used once available. See EAICD for structure, filename conventions and further details. See Calibration_Report for questions concerning the calibration.

本数据集收录了由贝皮科伦坡（BepiColombo）任务水星行星轨道器（MPO）航天器（spacecraft, s/c）搭载的MPO-MAG磁强计获取的标定后磁场矢量数据与工程内务数据（housekeeping data）。所有磁场数值均为经地面标定的纳特斯拉（nanotesla, nT）量级数据，所有工程内务数据均已转换为标准物理单位。数据集文件按任务阶段、工程与科学数据类别以及传感器类型进行分类存储。磁场数据可采用单位参考坐标系（Unit Reference Frame, URF）、航天器本体坐标系（Spacecraft Coordinates, SCF）或指定天球坐标系（如ECLIPJ2000：e2k）提供。本数据集仅基于地面标定结果计算生成，这意味着已校正仪器随温度变化的灵敏度、安装失准与偏移误差。但航天器自身带来的各类影响尚未完全消除，例如航天器磁场随时间变化产生的干扰信号。仅通过静态偏移（static_offset）标定文件，对航天器磁场的阶梯式恒定估值进行了扣除处理。若需开展严谨的科学研究，建议待官方发布衍生数据后再行使用。有关数据集结构、文件命名规范及更多细节，请参阅EAICD文档；有关标定相关的疑问，请查阅《Calibration_Report》标定报告文档。

背景与挑战

背景概述

该数据集来自欧洲空间局的BepiColombo任务，包含MPO轨道器上MPO-MAG磁力计获取的校准磁场矢量数据和辅助数据，数据经过地面校准处理，适用于科学初步研究，时间覆盖从2018年10月到2028年12月。数据集特点包括按任务阶段和传感器分类存储，但未完全消除航天器磁场影响，建议后续使用衍生数据进行深入分析。
