The Prediction of Spacecraft Disturbance Starlight Refraction and Navigation Simulation Research

Abstract:

The methods of starlight refraction navigation has very strict geometric requirements to starlight refraction direction, in order to capture the refraction of stars accurately, and avoid emerging the serious loss of accuracy of lost star, a forecasting method of interference refractive starlight is proposed in this paper. This method can consider all sorts of bodies under the influence of interference, and predict starlight direction that can happen refraction in the instant position of the corresponding spacecraft, so as to adjust the star sensor posture in advance for quick capture starlight refraction. At the same time, from the geometric relationships researching and analyzing the influence mechanism between refraction stars number and distribution by various interference, the influence of the simulation results show that refraction star distribute on both sides of the spacecraft orbit zonally, its number is closely related to the altitude. While through to accurately forecast on the starlight refraction direction, we can make the spacecraft navigation precision and capture refraction star speed increased by more than one times. Therefore, this paper has important value of engineering application.
