Abstract
A rotation rate sensor which uses a double ended tuning fork having a mounting base with only a single exclusive mounting surface. The mounting base is surrounded and centrally disposed within the body of the tuning fork. The mounting base is joined to the body by a suspension system which is also disposed within the body of the tuning fork. The tuning fork is mounted in the housing only at the single exclusive mounting surface.
