Abstract
Apparatus and associated methods relate to a vehicle attitude estimated as a function of predicted acceleration from the vehicle control system. In an illustrative example, a weighting module may dynamically combine IMU (Inertial Measurement Unit) with sensor motion data motion profile information from the vehicle control system. The weighting module may receive the predicted acceleration information via a data link with the vehicle control system. The dynamic weighting of inputs may be processed by an attitude estimator. An estimated attitude may be supplied to a display device, for example, to represent a real-time spatial orientation of the vehicle with respect to the gravity vector.
