A Constantly Computed Impact Point (CCIP) is a calculation provided by a weapon's sighting system.
It is a predicted point of impact found from the launch platform's movement, the target's movement, gravity, projectile launch velocity, projectile drag, and other factors that can be entered.
The HUD crosshairs will move around dependent on where the computer predicts the selected rocket, bullet or bomb will hit.
This system is normally used in aircraft, other large vehicles, or large static weapons, but it is in principle possible for such a system to be miniaturized for a man-portable firearm or Unmanned Combat Aerial Vehicle (UCAV).
[1] The Continually Computed Release Point (CCRP) inverts the principle of CCIP.
