Abstract：The navigation error in the inertial navigation system has a significant time accumulation effect,and it will have an adverse effect on the performance of the ejection seat.Therefore,it is necessary to carry out the error analysis of chair-borne inertial navigation to provide an objective basis for engineering applications.In this paper,the error model is established,the influence of the main error sources on the navigation accuracy is analyzed,and the inertial navigation under static,aircraft maneuvering flight and ejection seat and post-aircraft motion trajectory are simulated and analyzed,and the output system error of chair-borne inertial navigation is obtained.
