The invention relates to a method for providing dynamic state information for at least a part of a coordinate measuring machine, the coordinate measuring machine comprising a base, a probe head, a machine structure with structural components for linking the probe head to the base and at least one drive mechanism for providing movability of the probe head relative to the base. A dynamic model is defined with an actual set of state variables, the state variables being related to a set of physical properties of at least the part of the coordinate measuring machine and representing an actual state of at least the part of the coordinate measuring machine" and the actual state of at least the part of the coordinate measuring machine is derived by a calculation based on the dynamic model. According to the invention, a filtering process is executed with the dynamic model with deriving a set of prediction variables based on the state variables, the prediction variables describing an expected proximate state of at least the part of the coordinate measuring machine, measuring at least one of the state variables and determining a set of observables based on the measuring, deriving a set of successive state variables by comparing the set of prediction variables with the set of observables and updating the dynamic model using the set of successive state variables as the actual set of state variables. |
