Abstract

The solid-state Hemispherical Resonator Gyroscope (HRG) uniquely offers the benefits of small size, extremely long life, and ultrahigh reliability for spacecraft pointing and control application. The HRG also offers precision performance which can be scaled through control loop and electronics design tradeoffs. Delco Systems Operations has developed the HRG-based Space Inertial Reference Unit (SIRU), which has been designed to maximize the benefits of small size and high reliability and meet the medium grade performance of most spacecraft. The precision performance required for many imaging spacecraft has been achieved through selected modifications to the SIRU design. The result is a precision pointing IRU which maintains the inherent small-size, high reliability characteristics offered by the solid-state HRG. These attributes enable the weight reduction and life extension of precision imaging spacecraft. Modifications to the SIRU design for precision pointing applications have been implemented and characterized. These modifications and test results are described herein.
