The invention relates to a compact position measuring device with which the spatial position of a mobile element (5) relative a base (1) can be measured in a simple manner. The position measuring device comprises a length measuring device (6) and a goniometer (7) for measuring the angle of the element (5) about two rotational axes. The beam path used to measure the angle extends between the mobile element (5) and the base (1).
