The invention discloses a ground simulation zero-gravity test system suitable for unfolding an ultra-long light structure. The ground simulation zero-gravity test system comprises an X-direction follow-up execution mechanism, a Y-direction follow-up execution mechanism, a follow-up platform, a detection and control device, a gas-magnetic hybrid bearing, a suspension rope, a high-stability supporting frame and a light unfolding mechanism, wherein the high-stability supporting frame serves as a supporting body and is connected with the Y-direction follow-up execution mechanism. The lower part ofthe X-direction follow-up execution mechanism is connected with the Y-direction follow-up execution mechanism; the follow-up platform and the detection and control device are installed in the middleof the X-direction follow-up execution mechanism; the gas-magnetic hybrid bearing is attached to the follow-up platform through magnetic force; the lower end of the suspension rope is connected with the light unfolding mechanism; and the upper end of the suspension rope is connected with the gas-magnetic hybrid bearing. The unfolding characteristic requirements of large-range movement and low-friction follow-up of a light mechanism are met.
