AbstractThe pre-production model of an integrating wave solid-state gyroscope with differentiation (WSG-IGD) has found out the following feature of change of the measured values (Ωизм) to constant angular speed set to the sample Ω [radian/second]. Function Ωизм(t) contains not sinusoidal periodic component, to the greatest which first harmonic correspond amplitude Ωим1≈0,0066 Ω and circular frequency ω≈1,09Ω . By the analysis it is established that feature is caused by a methodical periodic error of measurement of a corner of orientation of a standing wave in the resonator. Using this feature, the way of experimental definition of scale factor (K) WSG-IGD is developed and tested. On the given sample the measured factor has made K=0.2773. Recommendations about application of ways of definition of scale factor WSG-IGD are considered.
