Cannon-launched guided projectiles (CLGP) are precision-guided munitions launched by howitzers, mortars, tank guns, and naval guns.
Those projectile main propulsion system is the initial kinetic shoot, directed as much as possible toward the target.
A secondary GPS or geocoordinates-based system then corrects the trajectory to increase target accuracy and fall closer to the target.
This system relies on electronic guidance and pre-programmed coordinates, submitted to the round before its launch.
