Research on Selection of Stargazing Window of High-Speed Vehicle

Star navigation technology can effectively improve the autonomous navigation ability of near space high-speed vehicle. The star navigation of high-speed vehicle is disturbed by the high-temperature gas emission in the flow-field. In order to realize effective star observation, it is necessary to stu...
