Process for the measurement of the absolute position of the movable, cyclic division mark carrier of an incremental position indicator or rotation indicator/resolver within and/or with regard to one of its divisional segments, periodically formed and/or delimited by the division marks on the carrier, with two scanning elements, stationarily arranged and addressing the division marks, which are positioned at such a distance from one another along the length or periphery of the segment that they deliver two sine- and cosine-like measurement signals which are evaluated on the basis of the arctangent function for position determination, by utilizing the values or components of a parameter vector identifying the measurement process, which is continuously redetermined during the measurement operation according to preset optimization criteria, for correction of the evaluation for disturbances and inaccuracies in the position indicator.
