低噪声位置测量是空间惯性传感器的基础，目前空间惯性传感器普遍采用电容式位置传感器。提出了一种电容传感器前端电噪声抑制的设计方案。在0.04 Hz以上频率下，获得了2×10−6pF/Hz 1/2的电容传感器样机，并讨论了进一步的改进。
Low noise position measurement is fundamental for space inertial sensors, and at present the capacitive position sensor is widely employed for space inertial sensors. The design for the possible suppression of the front-end electric noises for a capacitive sensor is presented. A prototype capacitive sensor with 2×10−6pF/Hz1/2at frequency above 0.04 Hz is achieved and further improvements are discussed.
