Radiation Hardened Controller

Reliable, capable, and radiation hardened control electronics are critical and needed for successful completion of postulated missile defense engagements. These electronics are used in motor controllers and divert and attitude control systems (DACS) for missile interceptors and space systems. The existing GBI Booster stage 2 and 3 TVCs, a.k.a. Electronics Control Unit (ECU), have not been hardened to HAENS and natural radiation environments. These controllers are critical for mission success since they drive electromechanical actuators used for pitch and yaw functions of stage 2 and 3 rocket nozzles. The successful completion of all 3 phases of this effort will result in a radiation hardened TVC design that will meet HAENS and natural radiation environment survivability requirements and show marked improvement in other performance parameters. The design approach will be used to reduce cost and extend utility across multiple electronic controller applications. During Phase 1, a prototype controller design will be upgraded to meet survivability requirements and a Phase 2 parts and prototype characterization plan will be developed.
