Tracking and application of IMM algorithm in mid-course of Booster-glide vehicle

Abstract

The booster-glide vehicle is one of the most important research targets in recent years that can change orbit by maneuvering and glide by jumping during flight. This paper focuses on the research and analysis of tracking the midcourse booster-glide vehicle’s trajectory. The interactive multi-model algorithm established by establishing the CS-CKF model and the free segment precise dynamics model is compared with the single CS-CKF model algorithm for analysis. The simulation results show that the interactive multi-model (IMM) algorithm based on CS-CKF and precision dynamics model has better performance in the midcourse tracking of the booster-glide vehicle.
