中国地震电磁卫星（CSES）部署了三个有效载荷来探测电离层的电磁环境。三轴磁通门磁强计（FGM）作为高精度磁强计（HPM）的一部分，测量从直流（DC）到15赫兹的频率范围内的地球磁场矢量。三轴搜索线圈磁强计（SCM）检测频率从几Hz到20 kHz的交流（AC）相关磁场，电场探测器（EFD）测量DC到3.5 MHz宽频段的空间电场。本工作主要对三种载荷在重叠探测频率范围内的一致性进行交叉校准，并首先对CSES的定时系统和EFD与SCM的采样时间差进行评估。提出了一种EFD与单片机波形数据采样时间同步的方法。以磁转矩（MT）信号为参考，验证了FGM和单片机在超低频范围内的一致性。一个自然的准周期电磁波事件验证了单片机和EFD在极低频和甚低频（ELF/VLF）频段的一致性。这项交叉标定工作有助于提升CSES的数据质量，并为近地轨道卫星类似的电磁探测解决方案提供有价值的见解。
The China Seismo-Electromagnetic Satellite (CSES) deploys three payloads to detect the electromagnetic environment in the ionosphere. The tri-axial fluxgate magnetometers (FGM), as part of the high precision magnetometer (HPM), measures the Earth magnetic vector field in a frequency range from direct current (DC) to 15 Hz. The tri-axial search coil magnetometer (SCM) detects the alternating current (AC) related magnetic field in a frequency range from several Hz to 20 kHz, and the electric field detector (EFD) measures the spatial electric field in a broad frequency band from DC to 3.5 MHz. This work mainly cross-calibrates the consistency of these three payloads in their overlapped detection frequency range and firstly evaluates CSES’s timing system and the sampling time differences between EFD and SCM. A sampling time synchronization method for EFD and SCM waveform data is put forward. The consistency between FGM and SCM in the ultra-low-frequency (ULF) range is validated by using the magnetic torque (MT) signal as a reference. A natural quasiperiodic electromagnetic wave event verifies SCM and EFD’s consistency in extremely low-frequency and very low-frequency (ELF/VLF) bands. This cross-calibration work is helpful to upgrade the data quality of CSES and brings valuable insights to similar electromagnetic detection solutions by low earth orbit satellites.
