Abstract

To overcome the intrinsic shortcomings of the stellar refraction model, this study examines the continuous correction of stellar refraction. First of all, the distribution rule of refraction stars is explored, followed by the location of the stars through Unscented Kalman Filter and continuous observation of multiple stars. Meanwhile, the constraint mechanism of stellar guidance is studied, involving available stars, star selection elements and design of the stellar guidance trajectory based on penetration planning. Furthermore, an inertial/stellar guidance planning method involving the optimal selection strategy and technology of the navigation star and the accurate calculation of star position is proposed. Finally, the composition and working principle of the stellar guidance system are introduced.
