| Abstract: | Fixing and adjustment errors of gyros in the photoelectronic stabilized platform impact the measuring accuracy of angular rate of the platform.The calculation method of the angular rate of the gyro stabilization platform is systematically studied in this paper.The emphasis is the calculation for the angular rate of the platform with cross coupling of sensitive axes of gyros.The theoretical calculation formula of the angular rate of the stabilized platform is obtained.On this base,calculation formula are obtained under an ideal condition and under the condition of the cross coupling of sensitive axes of gyros respectively.It is shown by simulations and experiments that the compensation for the cross coupling of sensitive axes of gyros can effectively improve the measuring accuracy of line-of-sight（LOS） rate. |
