“…The specific implementation of the swing force measurement method includes closed-loop and open-loop measurement methods. In the closed-loop measurement, the electromagnetic force is used to compensate for the effect of the thrust so that the measurement platform is in the random equilibrium and the electromagnetic force equals to the thrust [16]. The closed-loop measurement method can eliminate the interference of gravity and material rigidity on the measurement, and the measurement results are relatively more accurate.…”

“…Compared with the other two kinds of measurement methods, the target transfer measurement method is a non-contact indirect measurement, which can avoid the impact of measurement and control cable, thruster working noise, and vibration on the measurement results to a certain extent [5,13,16]. In addition, the target transfer measurement method has a simple structure and is easy to install and implement.…”

“…Accuracy is a measure of the error between the measured value and the true value of the measuring bench. For a high-performance measuring bench, it is not only required to be sensitive enough, the results have obvious repeatability, not affected by random errors, but also to ensure the measurement results [16]. In the measurement process, the system error is usually minimized to improve the measurement accuracy, and the accuracy needs to be calibrated through standard thrust and impulse.…”

Space micro-propulsion systems are increasingly considered an attractive option for station-keeping and drag-makeup purposes for the mass- and power-limited satellites due to their critical factors of simple design, small volume, and high specific impulse. These systems typically generate low-range thrust from nN to mN, and their impulses are less than mNs, making it difficult for conventional sensors to detect them directly. Consequently, the design of a special thrust stand is often necessary to measure these micro-propulsion systems. This chapter outlines recommended practices for the operation and calibration of three conventional measurement methods, along with the introduction of an impulse measurement stand developed at the National University of Defense Technology. The chapter presents the fundamentals, calibration method, and experimental results of the stand operation, while also analyzing error sources. Finally, the chapter discusses the demand and direction of micro-impulse measurement development.
