These are by no means the only factors that affect the accuracy of the
GPS system but they are often referred to in papers on this subject. A

exceed 12 m.
User Range Error (URE)
This is a parameter for the estimated error in range calculation due to
unknown factors. These include multipath, unmodelled atmospheric
effects, operator error and unpredictable orbital errors. The URE figure is
sent from SVs to GPS receivers and may be displayed in meters.
