The Taiji Laboratory for Gravitational Wave Universe has developed a micro-thrust measurement system spe cifically for ground thrust measurement of a micro Hall thruster. The thrust measurement system’s core component is the thrust stand, which is designed based on a hanging pendulum topology and has undergone four generations of iterative optimization. This thrust measurement system is capable of measuring the thrust in the range of 0–100 μ N with a resolution better than 0.1 μ N. This study presents ground thrust measurements for a ground-optimized version of the micro Hall thruster on board the Taiji-1 satellite. The Taiji-1 micro Hall thruster is currently the lowest power level Hall thruster in orbit and has a unique physical design that allows it to operate without an external cathode. The thrust measurement results demonstrate that the ground-optimized thruster can provide continuous thrust modulation in the range of 0.94–104.67 μ N, with a resolution superior to 0.2 N. This research provides technical support for ground testing and iterative optimization of micro-thrusters for the Taiji gravitational wave detection mission.
