| Abstract: | Internal charging effect is one of the main causes of spacecraft flight fault. According to the requirement of the ground simulation experiment with respect to the internal charging effect, a charge measurement method based on the vibration capacitance method is proposed. The physical structure of the sensor and the signal processing circuit are designed. The prototype of the measuring instrument is developed, and calibrated by test. The test results show that the instrnment features high linearity, good accuracy, and stable performance. |
