CIRUS & CIRUX-EX

The CIRUS (Compact Inertial Reference Unit for Space) and CIRUS-EX deliver strategic-grade attitude control, platform stabilization and pointing for space and defense applications, integrating four FOG sensors with full redundancy.

The units feature dual-redundant serial interfaces (MIL-STD-1553 and RS-422) for flexible I/O rates, and telemetry output format can be customized for specific user interfaces.
