Abstract

The invention discloses a relativistic astronomical effect navigator based on star sensor assistance and a navigation method of the relativistic astronomical effect navigator. The navigator comprises a star sensor, 2N interference apertures, 2N multi-degree-of-freedom adjusting brackets, a data processing and control system and a vibration isolation platform, the star sensor and the data processing and control system are arranged at the center of the multi-degree-of-freedom adjusting bracket, and the data processing and control system is positioned below the star sensor; the interference apertures are uniformly distributed on the vibration isolation platform by taking the star sensor as the center; and each multi-degree-of-freedom adjusting bracket is arranged between each interference aperture and the vibration isolation platform. The method can realize submillisecond-magnitude accurate pointing measurement, meets the high-precision pointing measurement requirement of the relativistic effect, and is suitable for engineering application.

Description

technical field [0001] The invention belongs to the field of instrument science and technology, and in particular relates to a relativistic astronomical effect navigator based on star sensors and a navigation method thereof. Background technique [0002] Relativistic effects such as aberration and gravitational deflection are directly related to the parameters of the aircraft in orbit, and astronomical autonomous navigation can be realized by measuring aberration and gravitational deflection. Aberration and gravitational deflection are generally only on the order of submilliarcseconds. Therefore, the basis of autonomous navigation based on relativistic astronomical effects is high-precision pointing measurement. [0003] At present, the pointing measurement accuracy of star sensors can only reach the milliarcsecond level, and there is no research on the instrument based on the submilliarcsecond level measurement accuracy and realizing the relativistic effect of autonomous na...
