On February 3, 2018, Zhangheng 1, the electromagnetic detection test satellite carried by the launch vehicle Long March 2, was successfully launched from the Jiuquan Satellite Launch Center. The satellite was named after the famous ancient Chinese astronomer Zhang Heng. It entered the intended sun-synchronous orbit. The success marks that China becomes one of the few countries owning the in-orbit geophysical field exploration satellite with high precision.
Zhangheng 1 is the first satellite launched according to China’s geophysical field exploration plan, and also the first space observation platform meant to be part of the integration of space, sky and earth of China’s seismic monitoring system, with the expectation of providing the country with valuable global geomagnetic field data for the first time.
