Abstract: This disclosure may generally relate to operations performed in a wellbore. More particularly, systems and methods may be provided for measuring the position of a tool and/or tubular string downhole. The present disclosure may be able to determine an accurate position change in a downhole tool without requiring surface equipment manipulation during measurement acquisition. A position measurement system may comprise a position measurement tool, wherein the position measurement tool comprises a sensor module and a telemetry module; and a marker, wherein the marker emits a signal measured by the sensor module.
