Abstract
In space environment, the charge will be collected on the surface of the spacecraft by the combination of the surrounding space plasma and photoelectric effect, forming a suspension potential different from the background plasma environment, that is, the surface charging phenomenon. The integrated monitoring system of plasma environment and surface charging includes 4 parts: omnidirectional electron spectrometer, omnidirectional ion spectrometer, surface potential probe and magnetometer. The main function is to detect the space plasma environment and the surface potential on the satellite, and to process, store and transmit the received signals. Ground testing and calibration have been done for all the four detectors, and the results agree well with the designed value.
