CIRUS
CIRUS-EX
A next-generation strategic-grade Fiber Optic Gyro (FOG) Inertial Reference Unit for spacecraft attitude control — four fully redundant gyros, rad-hard electronics, and dual-redundant interfaces built on more than 60 years of space heritage.
Four gyros, one integral chassis
Leveraging over sixty years of experience and proven performance in systems deployed in space, CIRUS is designed and qualified as the next-generation product of our heritage system. CIRUS and CIRUS-EX rate sensors deliver two different strategic grades of performance combined with the benefits of a compact, low-cost system in an integral chassis — four Fiber Optic Gyro (FOG) sensors operating in a fully redundant configuration for spacecraft attitude control, supporting DoD, NASA, and commercial missions.
