Abstract

Based on the working principle of the signal detection and servo feedback control of the electrostatic accelerometer, in this paper, the main electronic noise components affecting the measurements of the accelerometer are analyzed and the corresponding expressions are determined. The resolution of the designed electrostatic accelerometer is lower than 10 $^{- 9}$ m/s²/Hz $^{1 / 2}$ , which cannot be verified directly due to limitations imposed by the vibration of the ground environment. However, it can be evaluated indirectly by the testing of electronic noise under open-loop conditions. Through this process, the resolution of 3× 10 $^{- 9}$ m/s²/Hz $^{1 / 2}$ of the Taiji-1 inertial sensor was verified and found to be in agreement with results obtained in orbit.
