China Seismo-Electromagnetic Satellite (CSES) is the first space-based electromagnetic platform of China’s stereo seismic monitoring system and the first satellite of China’s geophysical field exploration satellite program that will be used to obtain the in-situ structural parameters and their effects on Earth’s magnetic field, space electromagnetic wave field, and ionospheric plasma. According to the objective of CSES, the parameters of the satellite orbit, satellite platform, and payloads, including the satellite footprint, magnetic and charging cleanliness control and boom design, and the isoelectric potential on the platform surface, are analyzed and tested. On February 2, CSES was launched, and the commission test proved that the system works well. The entire team has overcome difficulties in the R&D phase. The platform and payload can work in orbit, and the preliminary test shows that the main function and performance meet the demand and index designed by the project.
