Calibration Technique of Torque Output Characteristic of High Dynamic Maneuvering Device on Spacecraft

This paper studies a torque measurement method and device for the torque output characteristics of the spacecraft maneuvering device based on the air-floating platform and explains the composition and the measurement principle under ideal conditions. The accuracy of the system is analyzed in combination with the sensor installation error. With the installation angle calibrated, system measurement error can be compensated. Finally, the effect of the installation angle compensation on the accuracy is checked with a simulation. The system measurement accuracy is better than 0.06Nm.
