Abstract
Taking the engineering application of reusable booster vehicles (RBVs) as the research background, an effective navigation system scheme for rocket-powered auto-flyback RBVs is put forward in detail. First of all, the research state of RBVs in main research departments and three kinds of typically used feasible flyback options for RBVs are introduced. Based on an analysis of the characteristics of application background and engineering requirements, a feasible navigation scheme for a rocket-powered auto-flyback RBV is put forward, which consists of a strapdown inertial navigation system (SINS), global navigation satellite system (GNSS) and radio navigation equipment (radio). In order to realize navigation with high accuracy and dynamic adaptability, an improved dynamic information integration strategy is used for the navigation system, and simulation of the scheme based on a special trajectory is carried out. The theoretical analysis and simulation results indicate the effectiveness and feasibility of the navigation technologies.
