The invention relates to a two-dimensional turntable for a ground satellite simulator, which is characterized in that a rolling frame is arranged in a driven frame, a cross shaft is arranged in the rolling frame, first bearings are arranged on two sides in the driven frame, and two ends of a first rotating shaft of the cross shaft respectively extend out of the rolling frame and then are supported by the first bearings; a first brake assembly for limiting rotation of the first rotating shaft is arranged in the driven frame, second bearings are arranged at the two ends of the rolling frame, the two ends of the second rotating shaft of the cross shaft are supported through the second bearings correspondingly, and a second brake assembly for limiting rotation of the second rotating shaft is arranged in one end of the rolling frame; a reset assembly is arranged on the mounting plate, a reset rod is arranged on the upper side of the rolling frame, penetrates through the mounting plate and is reset through the reset assembly, the satellite simulator is mounted on the rolling frame, and the driven frame is arranged in the equipment unit frame in a liftable mode. According to the structural design, the frictional resistance moment can be reduced, and simulation of rolling, yawing and the like of the satellite simulator can be well achieved.
