“…As the first space‐based platform in China for both earthquake observation and geophysical field measurement, the China Seismo‐Electromagnetic Satellite (CSES; also called ZHANGHENG‐1), was launched successfully on February 2, 2018. Ten days later, it began its global observation (Shen XH et al, ). During its five‐year mission, it will provide nearly continuous data of natural electromagnetic (EM) field waveforms and spectra, in situ plasma parameters, electron density profiles and tomography, and energetic particle flux and energy spectra.…”

Four levels of the data from the search coil magnetometer (SCM) onboard the China Seismo‐Electromagnetic Satellite (CSES) are defined and described. The data in different levels all contain three components of the waveform and/or spectrum of the induced magnetic field around the orbit in the frequency range of 10 Hz to 20 kHz; these are divided into an ultra‐low‐frequency band (ULF, 10–200 Hz), an extremely low frequency band (ELF, 200–2200 Hz), and a very low frequency band (VLF, 1.8–20 kHz). Examples of data products for Level‐2, Level‐3, and Level‐4 are presented. The initial results obtained in the commission test phase demonstrated that the SCM was in a normal operational status and that the data are of high enough quality to reliably capture most space weather events related to low‐frequency geomagnetic disturbances.

The High Precision Magnetometer (HPM) on board the China Seismo‐Electromagnetic Satellite (CSES) allows highly accurate measurement of the geomagnetic field; it includes FGM (Fluxgate Magnetometer) and CDSM (Coupled Dark State Magnetometer) probes. This article introduces the main processing method, algorithm, and processing procedure of the HPM data. First, the FGM and CDSM probes are calibrated according to ground sensor data. Then the FGM linear parameters can be corrected in orbit, by applying the absolute vector magnetic field correction algorithm from CDSM data. At the same time, the magnetic interference of the satellite is eliminated according to ground‐satellite magnetic test results. Finally, according to the characteristics of the magnetic field direction in the low latitude region, the transformation matrix between FGM probe and star sensor is calibrated in orbit to determine the correct direction of the magnetic field. Comparing the magnetic field data of CSES and SWARM satellites in five continuous geomagnetic quiet days, the difference in measurements of the vector magnetic field is about 10 nT, which is within the uncertainty interval of geomagnetic disturbance.
