Compact Inertial Reference Units (IRU) for Space & Defense Missions. Ideal for military and space applications, the CIRUS (Compact Inertial Reference Unit for Space) &amp; CIRUS-EX IRUs are designed for strategic-grade performance in a compact, cost-effective package.The units integrate four Fiber Optic Gyro (FOG) sensors, and provide precise spacecraft attitude control, precision pointing for navigational accuracy, and platform stabilization.The units offer tailored telemetry formats to meet specific user requirements, with the IRUs’ dual-redundant serial interfaces (MIL-STD-1553 and RS-422) supporting flexible I/O rates.Key Features:
Dual Performance Grades: Achieves ARW &lt;100 μ°/√hr for exceptional precision.
Redundant Configuration: Four Fiber Optic Gyro (FOG) sensors with dual A/B electronics ensure high reliability and mission success.
Flexible Interfaces: Dual-redundant serial interfaces (MIL-STD-1553 and RS-422) support flexible I/O rates.
High-Reliability Electronics: Class S and Class K rad-hard components for robust performance in harsh conditions.
Power Flexibility: Individual power control for each sensor.
Thermal Management: User-selectable thermal set points for optimal operation in varying environments.
On-Station Commands: Capability to execute commands for enhanced situational awareness.
Versatile Mounting Options: Conductive and radiative vehicle-mount configurations.
Customizable Telemetry: Tailored telemetry formats to meet specific user requirements.
Applications:
Spacecraft Attitude Control: Ensures precise orientation and stability.
Precision Pointing and Navigation: Provides accurate guidance for defense and space missions.

The EMCORE CIRUS and CIRUS-EX are compact inertial reference units designed for strategic-grade spacecraft attitude control and precision pointing in military and space applications. Each unit integrates four fiber optic gyroscope sensors with dual A/B electronics for redundant operation, achieving angle random walk below 100 micro-degrees per root-hour in a cost-effective package suited for small satellites and defense space platforms.

Dual-redundant MIL-STD-1553 and RS-422 serial interfaces, Class S and Class K radiation-hardened components, user-selectable thermal set points, and individual sensor power control provide the flexibility and reliability required for long-duration space missions. CIRUS units are appropriate for spacecraft attitude determination and control systems, precision navigation payloads, and other defense space applications requiring compact, high-performance inertial sensing with on-orbit configurability.
