Illuminating gun system and trajectory correction strategy thereof

The invention relates to a patrolling gun system and a trajectory correction strategy thereof. Comprising an unmanned aerial vehicle, a holder structure and a support-free firearm, the holder structure comprises a firearm clamp, a target information acquisition device, a pitch axis mechanism, a supporting mechanism, a yaw axis mechanism, a suspension mechanism and a firing mechanism. A shell throwing window of the support-free firearm is far away from a clamp, faces the ground and is fixed to a firearm clamp of a holder structure, the holder structure is connected with an unmanned aerial vehicle platform through a suspension mechanism, a pitch axis mechanism is arranged on the firearm clamp, a yaw axis mechanism is arranged on the pitch axis mechanism, and the suspension mechanism is arranged on the yaw axis mechanism; the supporting mechanism is arranged on the side face of the pitch axis mechanism and used for reducing the influence of recoil force on a steering engine output shaft of the pitch axis mechani
