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.
