Ground-based comparative observation system in China Seismo-Electromagnetic Satellite mission

Considering satellite observation physical quantities and frequency-bands of China Seismo-Electromagnetic Satellite (CSES) as well as present situation of ground-based observation and comparative observation requirements in China, this paper proposed a design scheme for ground-based comparative observation system in CSES mission. According to the design scheme, three ground-based comparative observation systems Gufeng, Sitan and Pingcheng were established in Tianzhu area of Gansu Province, and preliminary observation data of electric field and magnetic field were obtained. The data analysis results show that the curves of electric field and magnetic field exhibit typical diurnal variation waveform with good synchronization and consistency, which can really reflect the intensities of electric and magnetic fields as well as their changes in a small region. Therefore, the result provides technical basis for satellite-ground joint observation and develop of stereo seismo-ionospheric monitoring system.
