Abstract :
The Hemispherical Resonator Gyro (HRG) has proven itself to be an ultra-reliable technology for space application with over 30 million operation hours and 100% mission success. Northrop Grumman Advanced Navigation Systems is developing a small size and lightweight terrestrial inertial sensor assembly (ISA) based on the HRG approach. This ISA will be the core of future inertial measurement unit (IMU) and inertial navigation system (INS) product lines.
