Abstract : The error of position in the determination of a point in two or three dimensions was studied since the method of least squares was founded. Knowledge of the errors over an extended region is still today obtained through point wise calculation and interpolation, a process which is tedious and time consuming. A new approach is based on the concept of the error field determined by the ground instrumentation. Differential equations based on the method of measurement can be established and their solution allows a concise over-all description of the error characteristics of the measuring system. Examples of such error fields in the two dimensional case are given for different systems. (Author)
