【摘要】 介绍了萤火一号(YH-1)火星探测器磁强计的标定方法及测试结果。根据磁通门磁强计的特点和本次任务的特殊性,为磁强计设计了灵敏度、线性度、噪声、稳定度、温度特性标定试验,给出了试验环境的构建和基本步骤,以及相关试验技术方法。试验结果表明:仪器在±256nT的磁场探测量程范围内,可实现分辨率0.01nT,噪声控制在0.01nT/Hz0.5(1Hz处),可为YH-1科学探测任务完成提供有效的探测载荷。更多还原

【Abstract】 The calibration technology and test result of the fluxgate magnetometer for YH-1 Mars probe were introduced in this paper.According to the feature of this mission,a calibration experiment of sensitivity,linearity,noise,stability and temperature feature for fluxgate magnetometer were designed.The constitution and basic steps of experiment environment,system,and experiment technology method were given out.The experiment results showed that the instrument would provide 0.01nT resolution ratio and less than 0.01nT/Hz0.5 at 1 Hz noise in range of±256nT,which could provide the performance good enough to achieve YH-1mission.更多还原
