Integrated Optics Inertial Navigation Sensor (IOINS)

In this proposal, we present a design for an Integrated Optics Inertial Navigation Sensor (IOINS) for use in a penetrating weapon. The proposed IOINS is based on a robust integrated optics glass-on-silicon waveguide architecture, hence it presents a more rugged, compact alternative to other technologies. Unlike other inertial navigation devices such as silicon micromachined inertial components, the IOINS enjoys the distinct advantage of continuous operation under high g forces without saturation. Thus, the IOINS can continue to navigate during extremely high impulse penetration. Moreover it is lightweight, compact, consumes a minimum of electrical power, and is potentially much more sensitive over a wider dynamic range than micromachined components. Its signal processing is simplified since it requires no crystal oscillator. In addition, the IOINS can be easily mass-produced at low cost to meet the performance specifications of a military inertial navigator. The outcome of this project will be a set of design specifications for the construction in Phase II of a prototype IOINS capable of inertial navigation in penetrating munitions.
