The invention relates to an aircraft-level ground test system for a spacecraft suspension potential control device. The aircraft-level ground test system is composed of an anode cover half-surrounding a hollow cathode, a hollow cathode emitter, a spacecraft, an aircraft vacuum test cabin, a bias power supply and a potential control discharge loop cable. The anode cap simultaneously realizes suspension potential difference simulation and plasma diffusion suppression functions of an aircraft relative to a far-end space plasma environment, and the bias power supply provides suspension potential difference simulation and discharge current. An aircraft suspension potential control discharge loop is formed by the bias power supply, the anode cap, the hollow cathode emitter, the aircraft cabin and the bias power supply. According to the system, on the basis that the suspension potential active control function and the performance simulation test requirement are met, the problem that the safety of outboard equipment of an aircraft is affected due to the fact that plasma generated by working of a hollow cathode diffuses in a vacuum test cabin is solved, and aircraft-level ground test verification of a suspension potential control device of a certain large manned spacecraft is achieved.
