range error

range error

[′rānj ‚er·ər]
(ordnance)
Difference between the range to the point of impact of a particular projectile and the range to the center of impact of a group of shots fired with the same data.

range error

As it pertains to armament delivery, it is the distance measured from the imaginary line drawn through the actual point of impact and the desired point of impact, both parallel and perpendicular to the direction of attack. Range error pertains to the distance along or parallel to the attack direction, whereas the distance across or perpendicular to the direction of attack is called the line error. See also circular error.

If the deer has an eight-inch-diameter kill zone, that leaves only three inches of margin for range errors.
Orbit errors are as small as 20 centimeters for routine images available within 1 day of collection, and range errors of well under 1 meter are verified: "We believe these claims because our test results show that TerraSAR-X SpotLight imagery has an overall ground accuracy of 1 meter and possibly even less, when projected to known elevations," states Ager.
