Abstract
An apparatus and method are disclosed for enhancing a navigation solution of a portable device and a platform. Motion sensor data may be obtained corresponding to motion of the portable device, such that a first filter may be configured to output a navigation solution and at least one second filter may be configured to use the motion sensor data to generate at least one value. The at least one generated value may then be used with the first filter to enhance the navigation solution output by the first filter.
