A support structure for turret and slip ring mounting, designed to control the sighting device and target plate for alignment and measurement testing.

Used for boresight alignment verification and synchronization accuracy testing.

Serves as a reference target for boresight and alignment accuracy inspection.

Includes power supply unit, control module, and operation computer required for system operation.

Includes a capacitor module for power stabilization and absorption of back electromotive force (EMF), as well as a discharge resistor for controlled voltage release.

Provides power and data transmission between the turret slip ring and external equipment.

Installed to prevent unauthorized access during turret performance testing.

Protects the sighting device from external impact during both operation and standby conditions.
