Update of CSES Mission

China Seismo-Electromagnetic Test Satellite (CSES) mission, being one of the China National Geophysical Fields detecting satellite missions, was proposed in the beginning of 2003 and cooperated with Italian Limadou mission.

The main objectives of CSES are:1) global geomagnetical field, its temporal-spatial distribution acquirement and related scientific issues research, 2) Ionospheric plasma environment and ionospheric response to natural and artificial events both from above and below, and 3) research of the mechanisms among Lithosphere-Atmosphere-Ionosphere Coupling as well as integrate research on Earth System science. The main CSES observing content include: Geomagnetical Fields and low frequency EM waves, In-situ ionospheric parameters and Ionospheric plasma tomography.

In the beginning of 2018, the CSES-01 launched in orbit successfully, which is due to flying onboard for 5 years in a solar synchronization circle orbit and carrying on 8 payloads. Since the launching event, CSES-01 sounded nice performance in-orbit accompanying with a large amount of data acquired and preliminary processing and application.

In the end of April of 2018, CSES-02 proved by China government following the CNSA-ASI MoU on CSES-02 signed in the Later of March of 2019. According to the draft scheme, CSES-02 will fly on the same orbit with CSES-01 but additional 1 payload than the 1^st one. CSES-02 was planned to be launched before the end of 2021 and about 2years onboard overlap with CSES-01.
