Summary:Systems and methods for tracking depth of a drill string. The method includes determining a measured elevation difference between a first position of a sensor and a second position of the sensor, based on measurements taken by an elevation measurement device, determining a calibration elevation difference between the first and second positions based on measurements taken by the sensor using markers positioned at predetermined elevations, and calibrating the elevation measurement device based at least partially on a relationship between the measured elevation difference and the calibration elevation difference.
