摘要
The system error of guidance instruments together with that of orbit tracking is considered and a mathematical model for estimating both of them is established. A thorough investigation of the accurate calculation of circumstance function and the effects of the system error model is made. Finally, the estimator of the two kinds of errors is presented based on nonlinear regression model and the accuracy of the presented estimator is given. Theoretical analysis and simulation results confirm the validity and effectiveness of this method.
