horizontal error from Test D.
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.
Despite this, the maximum
horizontal error calculated by the three GNSS/vehicle dynamic sensors integration algorithms was generally smaller than 10 m during the GNSS outage for 30 seconds.
Vertical error (deviation from 150 feet above ground level) and
horizontal error (lateral deviation from a path marked on the ground) were automatically recorded and were used to assess each participant's baseline ability to control the simulator.
