Summary: | The invention discloses an astronomical platform autonomous positioning method based on a tilt angle sensor, and belongs to the technical field of autonomous navigation. The invention aims to solve the problem that a traditional satellite navigation system loses the navigation capability under the interference of an electromagnetic environment. The method includes the steps of: enabling the azimuth of a tilt sensor to coincide with a platform coordinate system, and obtaining a conversion matrix of a platform relative to the horizontal plane through tilt information of the tilt sensor; obtaining an attitude matrix of the platform relative to the inertial coordinate system according to the platform attitude information of the star sensor; according to the current moment provided by the time service device, obtaining a conversion matrix of the inertial coordinate system relative to the earth coordinate system; and enabling the single chip microcomputer to perform resolving according to the conversion matrix of t |
