The Scalable SIRU™ family of products combines innovation and high reliability—with 100 percent mission success in more than 50 million on-orbit hours—for precision performance on space missions.
The LN-200S is a small, lightweight, highly reliable, state-of-the-art fiber-optic inertial measurement unit (IMU). The LN-200S comprises three solid-state fiber-optic gyros and three solid-state silicon Micro Electro-Mechanical Systems accelerometers in a compact package that measures velocity and angle changes in a coordinate system fixed relative to its case.
The LR-450 incorporates Northrop Grumman’s milli-HRG™ (mHRG™) Precision Space Gyroscope, which uses the same critical quartz components — high-Q resonator and inner electrode assembly — employed in Northrop Grumman’s proven hemispherical resonator gyroscope (HRG) technology. The HRG has achieved more than 70 million error-free hours in space missions.
