The Error Analysis of Gyroscope Drifs to the Rate Azimuth Platform System

Abstract:

To master the influence of deterministic system error to navigation system, so can accurately present the precision index of gyroscopes and accelerometers, which are the main components of rate azimuth platform inertial navigation system, and initial calibration precision. With the error equations under static state, the characteristic equation of rate azimuth platform inertial navigation system is set up. Based on the solutions of the error equation, and the system error characteristics caused by the gyroscope drifts are deduced with analytical method.
