With a self-designed very-low-power arcjet thruster and thrust measurement devices, thrust performance, i.e., specific impulse and thrust efficiency, and IV Characteristic with ammonia propellant have been systematically measured and analyzed. Experimental results show that the arcjet thruster can stably operate at input power lower than 100 W when gas feeding rate is in the range of 150 mL/min to 450 mL/min, and the maximum specific impulse is close to 250 s.
