Abstract

A locating system for determining a current position in an elevator shaft of an elevator system extending in a main extension direction includes a first distance sensor by which a first distance and a second distance, which second distance is perpendicular to the first distance, from a first reference element can be measured, as well as a tilt sensor by which a rotation about a horizontal first axis and a horizontal second axis perpendicular to the first axis can be measured, and a measuring system by which a position of the locating system can be determined in the main extension direction of the elevator shaft.
