CIRUS-EX

Overview

L3 Technologies has been the premier supplier of mission-critical precision pointing and navigation systems since the early days of the U.S. space program. Leveraging over sixty years of experience and proven performance in systems deployed in space, we have designed and qualified the Compact Inertial Reference Unit for Space (CIRUS) as the next-generation product of our heritage system. The 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.

Both CIRUS and CIRUS-EX systems feature four Fiber Optic Gyro (FOG) sensors in a fully redundant configuration for spacecraft attitude control, supporting DoD, NASA and commercial missions.
