Abstract: DEMETER (Detection of Electro-Magnetic Emissions Transmitted from Earthquake Regions) satellite, the first electromagnetic satellite specially aiming to earthquake monitoring in the world, was launched in 2004 by France, and ended in the end of 2010, with operating time of 6.5 years. The data along more than 30000 orbits were obtained, which provided a solid data foundation for the research in earthquake monitoring and ionospheric physics. Scientists in many countries carried out a number of earthquake application studies by using the data from this satellite, with hundreds of paper published, and pushed the research in seismo-electromagnetic satellite to a new peak. CSES (China Seismo-Electromagnetic Satellite), the first space satellite for geophysical field detection in China, was successfully launched on February 2, 2018. At present, its in-situ commission has been finished, and the satellite has been put into service, with the scientific data released to the public officially. Under this condition, it is important to summarize and retrospect the improvement and achievements in technology and science from DEMETER, in order to maximize the effectiveness of CSES, and transform the space electromagnetic detection to the operational run in earthquake investigation. The remarkable progresses from DEMETER satellite will be introduced in this paper, and the future development domains are suggested in space electromagnetic detection technology and scientific research combined with the characteristics in CSES satellite.
