See also: point of impact

In the most basic counterbattery tracking of weapons fire, the point of origin (POO) is the set of geographical coordinates from which a weapon was launched. There are a number of refinements of the concept related, variously, to the means by which launch was detected, if the weapon was launched from the ground surface, and if the warhead is unitary or made up of submunitions.

Detection system[edit]

Countersniper[edit]

Other than surface launch[edit]

Submunitions=[edit]

C-RAM[edit]

Counter-rocket, artillery and mortar systems can use POO information to plan engagement geometry for interception of the projectile, and to predict the point of impact to give warning.
