Abstract:

The stability of the satellite-bone gyroscope combination will directly affect the measurement accuracy of attitude variation tested by an attitude and orbit control system.The factors of output zero-offset stability which affect the hemispherical resonator gyroscope unit are analyzed in this paper，and the mechanism of temperatures impact on output variation is studied，with the relevant solutions proposed.The engineering practice shows that these measures improve effectively the zero-bias stability of the hemispherical resonator gyroscope unit at lower costs.
