Evaluation model for error compensation of inertial guidance system

Error compensation of the inertial guidance system is a simple and effective method for improving the missile firing precision. The system error model and noise model must be built first for evaluating the effect of the compensation. Based on the study of the system model in different flight conditions, and by use of real-time compensation in inertial guidance, a method is put forward for selecting the error compensation model and the model of compensation evaluation based on the engineering background. The simulation indicates that this method is propitious to error parameter identification and the compensation precision evaluation.
