    Abstract: The present invention relates to a method for determining the spatial position of objects, in particular medical objects. First position data is acquired that describes a spatial position of an object in a first coordinate system. First transformation data is acquired that transforms the object's position from the first coordinate system to a second coordinate system. Based on the foregoing data, second position data is acquired that specifies the spatial position of the object in the second coordinate system. Second transformation data is acquired that transforms the object's position from the second coordinate system to an inertial coordinate system. Based on the second position data and the second transformation data, inertial position data is determined that specifies a position of the object in the inertial coordinate system.
