Abstract
An inertial instruments uses a suspension structure that is exterior to and surrounds a cup shaped inertial mass which carries torquing magnets within the cup. Torquer coils are also located within the cup. In a preferred embodiment, axially magnetized disc magnets within the cup cooperate with toroidal torquer coils. In other embodiments segmented or bar magnets are used. The instrument can be used either as a gyroscope by coupling the suspension to a rotor, or as an accelerometer.
