The present application relates to the technical field of laser countermeasure equipment, and provides a laser countermeasure launching device, which comprises a platform, a laser launcher arranged above the platform, a sighting scope fixed to one side of the platform, and a correction structure fixed to the top end of the platform. The correction structure is arranged to, when an electric push rod drives a moving plate on one side above the platform to move through a connecting plate, make the moving plates on both sides above the platform move reversely under the action of a hinged rod and a movable plate, enhance the stability of the moving plate when moving under the action of a sliding seat, make the moving plate after moving drive a clamping seat to move reversely through a supporting seat, make the clamping seat after moving clamp one side of the laser launcher, and make the laser launcher centrally fixed left and right. Under the action of the clamping seat, the laser launcher is centrally fixed up and down, and then the center line of the laser launcher and the center line of the sighting scope are collinear, thereby completing parallel calibration of the optical axis and the visual axis, and ensuring that the laser hits the target accurately when aiming.

The present application relates to a kind of flexible solar wing for sun synchronous orbit satellite constellation and on-orbit control method, solar wing is flexible stacked structure, stack on satellite body in retracted state, solar wing includes oppositely arranged single wing, the single wing includes: substrate assembly, it is configured to carry out photoelectric conversion, the substrate assembly includes: rigid substrate and several flexible substrates;Unfolding mechanism, it is configured to provide unfolding stiffness for solar wing, to ensure that the flexible substrate keeps planar form;And unfolding motor, it is configured to drive the unfolding mechanism unfolding or folding, to realize the retraction or unfolding of solar wing;First solar wing driving mechanism and lifting mechanism are provided between oppositely arranged single wing.The present application is overall used flexible stacked structure form retraction envelope size small, light in weight, does not need additional use satellite attitude control system to carry out attitude adjustment and realizes sun tracking.
