Abstract
The present invention generally relates to systems and methods for determining precision vehicle orientation information. The system includes an inertial measurement unit having a chassis with a first interior surface, an inertial sensor assembly disposed within the chassis and having a first exterior surface, and integrated suspension elements mounted to the first interior surface and the first exterior surface. The integrated suspension elements include a first sensor that senses a displacement measurement of the inertial sensor assembly with respect to the chassis. The displacement measurement is used to determine an angular deflection.
