The Influence of Initial Error to the Rate Azimuth Platform Inertial System

Abstract:

To lower the cost of the gravity passive navigation system, a rate azimuth inertial platform with a gravity sensor on it was put forward to constitute a navigator with gravity measuring, combined with digital gravity map, the system would come to a simple passive navigation system 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 initial navigation error are deduced with analytical method.
