The two-axis turntable can meet the turning-over and rotation requirements of conventional satellites. However, the two-axis turntable does not have a height lifting adjustment function after the satellite turns over to a horizontal state. For the satellite with a large-volume envelope or a long-size external load single machine, after the satellite body or the external load single machine is turned to a horizontal state, the satellite body or the external load single machine is easy to collide and interfere with the two-axis turntable body, so that the satellite cannot finish turning operation by using the existing two-axis turntable.
