Industry:Military
Prediction of the point on the earth’s surface where a specific RV will impact, usually specified in terms of the circular error probable. The estimate includes the perturbing effects of the atmosphere and resultant uncertainties.
Industry:Military
A tube containing all the objects originating from launch sites and aimed at targets whose spacing is close enough to permit the tube around the object trajectories to be represented by a single trajectory in battle management computation.

Industry:Military
An indicator of the delivery accuracy of a weapon system, used as a factor in determining probable damage to a target. It is the radius of a circle within which half of a missile’s projectiles are expected to fall or there is a 50% probability that a single projectile shall impact.
