Some of the interference factors cannot be definitely quantified (e.g. the current state of the atmosphere and it's influence on the signal runtime).
Still, these interferences equally effect neighboring points; thus, the relative positioning (the position of the points to each other) is far more precise than the absolute position (in the WGS 84). Here, “neighboring” means distances to about 100 km. The functional principle of DGPS is to quantify the deviation of the measured position to the actual coordinates on the earth's surface.
