Analysis of Velocity Deviation of Satellite-Rocket Separation and Orbit Accuracy of Satellite Caused by Multiple Factors

Abstract

This paper focuses on the problems of separation velocity deviation and satellite orbit accuracy during the satellite-rocket separation process of spring energy storage, based on the separation dynamics model of satellite-rocket separation, analyze the separation velocity deviation of satellite-rocket separation caused by the satellite centroid deviation, the upper stage centroid deviation of the rocket, the installation position offset, and use the orbit simulation software to study the influence of the orbit accuracy caused by separation velocity deviation, and summarize the influence rules and main influence factors of satellite-rocket separation velocity deviation and satellite orbit accuracy.
