An elevator system includes an elevator car, an elongate tension member operably connected to the elevator car and configured to move the elevator car, and an elevator car position measurement system. The elevator car position measurement system includes a pulse generator configured to transmit a pulse along the elongate tension member; and a detector unit configured to receive the pulse from the pulse generator after the pulse has been transmitted along a length of the elongate tension member and to record a time at which the pulse is received. One of the pulse generator and the detector unit is arranged to move within the hoistway dependent on a position of the elevator car within the hoistway, such that a length of the elongate tension member along which the pulse is transmitted changes dependent on a position of the elevator car within the hoistway.
