Advanced Inertial Reference Units for Space Applications
The CIRUS (Compact Inertial Reference Unit for Space) and its enhanced version, CIRUS-EX, provide high-precision attitude control, stabilization, and pointing capabilities tailored for aerospace and defense sectors. These units incorporate four Fiber Optic Gyroscope (FOG) sensors, ensuring complete redundancy for reliable performance.
Flexible Connectivity and Customization
Both models are equipped with dual-redundant serial interfaces, including MIL-STD-1553 and RS-422, allowing for adaptable input/output rates. Users can also customize the telemetry output format to suit specific interface requirements.
