Method and system for estimating vehicle body tilt

Vehicle body tilt, representing a difference between a vehicle body frame of reference and a wheel-base frame of reference, is determined by obtaining information from sensor assemblies for the vehicle body and for the wheel-base. Navigational solutions are generated for the sensor assemblies using motion sensor data from the assemblies and absolute navigational information. Correspondingly, vehicle body tilt is determined based at least in part on the vehicle body navigation solution and the wheel-base navigation solution.
