Abstract: Near space is at the interface of aeronautics and astronautics issues and has a significant strategic value. Hypersonic vehicle is an important carrier for the forces deployment in near space and has entered its application stage. The flight environment and mission condition of near space hypersonic vehicles require better performance of the navigation system. This paper summarizes the development of navigation technology on near space hypersonic vehicles, analyzes the application of astronomical navigation technology, and puts forward five key research directions, including efficient star map identification, optical error model, field of view observation mechanism, attitude update rate, and miniaturization and modular engineering. The results can be used as a reference for the design of celestial navigation system for near space hypersonic vehicles.
Key words: near space, hypersonic vehicle, celestial navigation system, efficiency of star identification, aero-optical effect, wide-field observation, update rate of star identification
