Spectrum red shift antimonous navigation method for spacecraft

Abstract

The invention provides a spectrum red shift antimonous navigation method for spacecraft. The method includes: directly using solar celestial bodies as light emitters in the solar system; allowing a spacecraft to receive spectral information by spacecraft-carrying spectrum red shift measurement sensors; acquiring speed parameter of the spacecraft according to spectrum red shift measured parameters and spacecraft attitude information measured by spacecraft starlight sensors; and acquiring location parameters of the spacecraft by integration. The principle of the method is simple, the method is novel and is new breakthrough in spacecraft autonomous navigation methods, the means of spacecraft navigation is expanded, navigation capacity is increased, and true autonomous spacecraft navigation is realized. The method is directly applicable to autonomous navigation tasks for deep space exploration in China, has promising application prospect in the field of deep space exploration, and provides references for antimonous navigation in near-earth spacecraft.
