Abstract
An ionization contact potential difference gyroscope including a housing enclosing a first and second electrode with a gas, further including an ionization source capable of providing ions from the gas, and a contact potential difference measurement circuit that is capable of measuring an electrical signal related to the amount of ions striking at least one of the two surfaces. The measurement circuit of the present invention is capable of sensing the small amount of electrical current flowing as the electrons and ions strike one or both of the surfaces.
