The method of calibrating the dynamic error model coefficients of a strapdown gyro using the uniform angular velocity function of three-axis turntable was introduced.At first the relationship among the output of the calibrated gyro,error model coefficients and three uniform angular velocities exerted by three-axis turntable was calculated.Then harmonic amplitude vectors of the gyro output were achieved by Fourier analysis method while the different velocity ratios of the middle axis and the inner axis being given,the structure matrix and the information matrix were also gained.Finally the optimum three-axis velocities test plan using three-axis turntable is selected by determination values of the information matrix versus the outer axis velocity.

For analyzing the formation of additional errors, and setting up the error compensation model for dynamically tuned gyros(DTG) under compound overload-vibration environment, the finite element analysis software ANSYS was used, starting with structure analysis, for establishing the DTG's entity model and finite model, calculating the nutation frequency of DIG, and comparing them with experimental data, which verify the correctness of the models. The dynamic characteristic of DTGs under overload-vibration environment was analyzed, and the axial displacements of various nodes were acquired; and combining them with applied load, the DYG's drifting rotating velocity was obtained by calculating. In addition, the DTG's inherent frequency and correlative vibrating mould were acquired by modal analysis and calculating.
