ABSTRACT:
A tracking system is provided for tracking while determining the position of a point relative to a datum and includes a carriage (4) rotatably mounted on a frame (1) and which can rotate around a precision sphere (2). An interferometer (16) is mounted so as to rotate with the carriage (4), such that a mechanical center of rotation of the device and the measurement datum of the interferometer coincide at the same point.
