ABSTRACT:
An exemplary navigation system uses a master navigation component at a first location with a first sensor in a vehicle and a slave navigation component with a second sensor at a second location that is a variable displacement to the first location due to physical deformation of the vehicle. Static and dynamic location components provide static and dynamic information of the displacement between the first and second locations. A flexural model based on the deformation characteristics calculates the dynamic displacement. An error estimator estimates errors in the navigation measurement data of the slave navigation component based on the displacement information. The master navigational component corrects the navigation measurement data of the slave navigation component based on the determined error, translates the corrected navigation measurement data of the slave navigation component into navigation measurement data in its coordinate system, and combines the output of the second sensor based on the corrected navigation measurement data with the output of the first sensor into a combined result.
