Active suspension type satellite antenna three-dimensional extension testing device

The invention provides an active suspension type satellite antenna three-dimensional extension testing device. The active suspension type satellite antenna three-dimensional extension testing device comprises a controller, a two-dimensional horizontal motion mechanism, a vertical constant-tension adjusting mechanism, an angle measuring mechanism, a support mechanism and a lifting mechanism. The support mechanism is connected with the lifting mechanism, the two-dimensional horizontal motion mechanism is connected with the lifting mechanism and the support mechanism, the vertical constant-tension adjusting mechanism is connected with the two-dimensional horizontal motion mechanism, the angle measuring mechanism is connected with a vertical constant-tension adjusting mechanism, and the controller controls the two-dimensional horizontal motion mechanism, the vertical constant-tension adjusting mechanism and the angle measuring mechanism. The active suspension type satellite antenna three-dimensional extension testing device has the advantages of being simple in structure, easy to operate, high in positioning precision and high in response speed and can meet the requirements of satellite antenna ground three-dimensional extension testing.
