horizontal error


Also found in: Acronyms, Encyclopedia.

horizontal error

The error in range, deflection, or in radius, which a weapon may be expected to exceed as often as not. Horizontal error of weapons making a nearly vertical approach to the target is described in terms of circular error probable. Horizontal error of weapons producing elliptical dispersion pattern is expressed in terms of probable error. See also circular error probable; delivery error; deviation; dispersion error.

The IT data set included: acquisition time, acquisition start time, Iridium CEP radius, Iridium latitude, Iridium longitude, GPS fix time, GPS fix attempt, GPS latitude, GPS longitude, GPS horizontal error, activity count, receive time, repetition count, GPS satellite count, mortality and transmission error.
A shallower weapon trajectory would magnify this induced horizontal error.
To see the effect of practice on a pilot's ability to acquire the pathway, a separate analysis of vertical and horizontal error across trials was conducted.
However, because RMSE tends to inflate larger errors, and because the horizontal error in this experiment was approximately one order of magnitude greater than vertical error, mean absolute error (MAE) was chosen as the measure of horizontal tracking performance.
For example, if five points were deducted due to 5 horizontal errors, then 51 would be divided by 56 for a percent score of 91.
At the poles, where illumination rarely provides more than a glimpse of the topography below the crater peaks, we found systematic horizontal errors of hundreds of meters (hundreds of yards) as well.
