System for multiple navigation components
First Claim
1. An apparatus, comprising:
- a master navigation component that establishes a first coordinate system; and
one or more slave navigation components that determine navigation measurement data of the one or more slave navigation components each in their own secondary coordinate system;
wherein the one or more slave navigation components provide the navigation measurement data of the one or more slave components each in their own secondary coordinate system to the master navigation component;
wherein the master navigation component compares the navigation measurement data of the one or more slave components each in their own secondary coordinate system to navigation measurement data for the master navigation component in the first coordinate system;
wherein the master navigation component translates the navigation measurement data of the one or more slave navigation components in the second coordinate system into navigation measurement data of the one or more slave navigation components in the first coordinate system.

Abstract
An exemplary navigation system uses a master navigation component at a first location in a vehicle and a slave navigation component 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. An error estimator estimates errors in the navigational measurement data generated by the slave navigation component based on the navigational measurement data generated by the master navigation component and the displacement information provided by the static and dynamic location components. The master navigation component corrects the navigation measurement data of the slave navigation component based on the determined error and translates the corrected navigation measurement data of the slave navigation component into navigational measurement data in its coordinate system.
