Aerospace Instrument-Making Annotation << Back A mathematical model of the temperature drift HRG Redkin S.P. In experimentally investigated the variation of the drift velocity of the hemispherical resonator gyroscope in the long run different corners of the elastic wave resonator and its resonance frequency. Shows a characteristic change π-periodically depending on the angle of the drift velocity of the elastic wave resonator in the long run. Provides a methodology to define a variable and constant components of the periodic dependence of the drift velocity. Defined exponential nature of the resonant frequency of the hemispherical resonator gyroscope in the run. The mathematical model of the hemispherical resonator gyro drift velocity for the changes in temperature of the resonator (the resonant frequency) and the angle of the elastic wave. Calculated the residual drift velocity hemispherical resonator gyro start using algorithmic compensation built on the basis of the developed mathematical model of the drift velocity. Key words: HRG, drift velocity HRG, elastic wave resonator, resonance frequency HRG, a mathematic model of the drift velocity, algorithmic compensation of the drift velocity.
