Position measuring device for measuring the relative pose of two objects, which are movable with respect to one another, in an advance direction and in further degrees of freedom (Y, Z, RX, RY, RZ), having a carrier body, which is elongate in the advance direction and has measurement graduations (T11-T26), and having a scanning assembly that is movable with respect thereto, having a plurality of scanning units (A11-A26) for scanning the measurement graduations (T11-T26), characterized in that at least three surfaces of the carrier body in each case carry a first measurement graduation (T11-T16) and a second measurement graduation (T21-T26), wherein the first measurement graduation (T11-T16) and the second measurement graduation (T21-T26) each have a succession of graduation lines and the graduation lines of the first measurement graduation (T11-T16) are inclined with respect to the graduation lines of the second measurement graduation (T21-T26); at least one of the scanning units (A11-A26) for scanning the respective measurement graduation (T11-T26) at a scanning site is assigned to each of the first measurement graduations (T11-T16) and each of the second measurement graduations (T21-T26), wherein said two scanning units (A11-A26) are each arranged such, and the graduation lines of the two measurement graduations (T11-T26) are inclined in each case with respect to one another such, that in each case two planes which are perpendicular to one of the surfaces of the carrier body and which each extend in the direction of the respective graduation lines of one of the measurement graduations (T11-T26) through the scanning sites of the two scanning units (A11-A26) respectively assigned to one of the surfaces have a common axis of intersection (S1-S6) and that the resultant three intersection axes (S1-S6) extend through a common point. a scanning assembly that is movable with respect thereto, having a plurality of scanning units (A11-A26) for scanning the measurement graduations (T11-T26), characterized in that at least three surfaces of the carrier body in each case carry a first measurement graduation (T11-T16) and a second measurement graduation (T21-T26), wherein the first measurement graduation (T11-T16) and the second measurement graduation (T21-T26) each have a succession of graduation lines and the graduation lines of the first measurement graduation (T11-T16) are inclined with respect to the graduation lines of the second measurement graduation (T21-T26); at least one of the scanning units (A11-A26) for scanning the respective measurement graduation (T11-T26) at a scanning site is assigned to each of the first measurement graduations (T11-T16) and each of the second measurement graduations (T21-T26), wherein said two scanning units (A11-A26) are each arranged such, and the graduation lines of the two measurement graduations (T11-T26) are inclined in each case with respect to one another such, that in each case two planes which are perpendicular to one of the surfaces of the carrier body and which each extend in the direction of the respective graduation lines of one of the measurement graduations (T11-T26) through the scanning sites of the two scanning units (A11-A26) respectively assigned to one of the surfaces have a common axis of intersection (S1-S6) and that the resultant three intersection axes (S1-S6) extend through a common point.
