  • Patent number: 9033231
    Abstract: Disclosed is an automatic correction apparatus for a trajectory of a projectile from a firearm of which a sight and a gun barrel are installed in parallel, the apparatus including: a distance measurer which is installed in parallel with the sight and measures distance from a target to be hit; a central processing unit which calculates a correction value for parallelization between the gun barrel and the sight so that a trajectory curve and the target can intersect with each other on the basis of the distance measured by the distance measurer; and a parallelization adjuster which connects the sight and the gun barrel and adjusts axial parallelization between a sight line of the sight and the gun barrel on the basis of the parallelization correction value calculated by the central processing unit. With this, the trajectory of the projectile is automatically corrected in accordance with the distance from the target, and thus quick and correct aiming and firing are possible.

  • Publication number: 20110288804
    Abstract: Disclosed are a sighting apparatus for a remote-control shooting system and a sighting alignment method using the same. The sighting apparatus for a remote-control shooting system including a firearm installed in a firearm platform rotatable in up, down, left and right directions, and an observation camera installed to be position-adjustable in at the firearm platform, the sighting apparatus includes: a sighting unit which is fastened to the firearm with a zeroing unit precisely up, down, left and right adjustable therebetween, and takes a first image as zeroed; and a controller which controls the firearm platform so that an sighting indicator (e.g., a line) of the first image taken by the sighting unit can be aligned with a target, and aims at the target.
