Astronomical navigation and positioning technology is the ideal GNSS navigation alternative technology, the key of astronomical navigation and positioning technology is the all-sky star sensitive, the traditional all-sky star sensitive optical system are used in a small field of view program, the use of two-axis rotary table to achieve the search and follow the star, the existence of the system is large, heavy weight, expensive problems, it is difficult to expand the application. This paper discusses Honeywell, DRAPER Labs, TREX Enterprises and other companies to solve the GNSS denial environment related to astronomical navigation products, rotating lenses, slicing lenses and other all-sky star-sensitive device new system optical system research, for all-sky star-sensitive device new system optical system to provide reference.
