LEAST-SQUARES FORMULA FOR ZERO ERROR OF ELECTROMAGNETIC DISTANCE MEASURING INSTRUMENTS

The zero error of electromagnetic distance measuring instruments is a near-constant systematic error, which has the same effect on measured distances. This paper presents a least-squares formula for this correction based on the division of a baseline into m subbaselines, and measuring all possible distances between marked points. Validity of the formulation is verified by 2 examples.
