Analysis of impact of gyroscope synthetical error on an electric-optical stabilized control system

As one of the key components on a seeker, EO stabilized platform on a missile, gyroscope is directly relative to errors of servo systems. Main errors of gyro, such as bias drift and scale factor nonlinearity, are added to a servo system, the result is analyzed to illuminated that how a gyro has effect on a seeker servo system. With the mathematical models of a gyro and a seeker, the principle of choosing a gyro is theoretically deduced first and then two gyros model with different main parameters are added into the same gimbals model, the errors of servo systems are compared to prove the deduction. Final conclusion is helpful for choosing proper gyros in a seeker servo system.
