| Abstract: |
| Due to the particularity of GEO orbit space environment, temperature, irradiation electron energy, and environmental factors such as beam density will affect the charging and discharging effect of the orbital spacecraft solar array. To grasp the effect on solar array electrostatic discharge in GEO orbit space, with the solar array as the research object and based on the mechanism of solar array and its current research status, a solar array electrostatic discharge test circuit was designed. Experiment parameters and the test procedures of solar array electrostatic discharge were determined. The experimental study on the characteristics of solar array electrostatic discharge under the condition of certain electron energy and beam density was carried out, and the influence of environmental factors on solar array electrostatic discharge was obtained. The research shows that the electrostatic discharge frequency and discharge current amplitude are related to the ambient temperature. The higher the temperature is, the smaller the discharge frequency is, and the discharge current amplitude decreases accordingly. The main energy of the discharge current is concentrated in the frequency band below 10 MHz. The research results provide reference for the analysis of electrostatic discharge effect and protection design of spacecraft. |
