Method for optimizing a track position The invention relates to a method for optimizing a track position and for guiding a track-mounted track construction machine after a measuring drive with a track mounted track measuring carriage (A) having at least two wheel axles supported on a machine frame (21), a navigation unit, a device (7, 6, 9, 10) for pressing the wheels (1) against the rail (12) and an odometer (24) for measuring an arc length (s) of the rail (12). In order to create advantageous measuring conditions, a measuring drive is first carried out with the track-mounted track measuring car riage (A) equipped with an inertial navigation unit (INS, 5), the wheels (1) of which are pressed against the rails (12), wherein the length of the arc is meas ured with the odometer (24), the angular position (AL, AO, AG) of the inertial navigation unit (INS, IMU, 5) is measured against a Cartesian reference coordi nate system (x, y, z) and stored, and that after the measuring drive coordinate points (Pi) of the track (A, e, Pi) of the navigation unit (INS, 5) are calculated in space from the stored angular positions (A, AO, AO) by means of compensa tion calculation and from the thus optimized coordinate points (P) of the track(A, e, Pi) a locus image (1) is formed by zeroing the z-components and a longitudi nal section (2) by zeroing the x-components, after which a curve determined by means of mathematical connection functions is laid through the coordinate points (Pi).
