    Abstract: PROBLEM TO BE SOLVED: To provide a more accurate position measurement system using a calibration which takes less time than a conventional calibration method.SOLUTION: A position measurement system includes a first part EG, a second part ES and a computational unit. The first part and the second part determine a position of a first member relative to a second member by providing a position signal representing a position of the first part relative to the second part. The computational unit comprises an input terminal for receiving the position signal. The computational unit is configured to, in use, apply a conversion to the position signal to obtain a signal representing a position of the first member relative to the second member, and apply an adjustment to the conversion to at least partly compensate for a drift of the first part or the second part or both. The adjustment is based on a predetermined drift characteristic of the first part or the second part or both respectively. The predetermined drift characteristic includes one or more base shapes of the first part and/or the second part.
