Design Method of Star Catalog for Interferometric Star Sensor Based on Fibonacci Grid Points
摘要
Abstract
The construction of navigation star list is an important task in the design stage of star sensor system.Because the interferometric star sensor only retains part of the interference order,the energy of the image point is low.The spectral component divides a beam of starlight into mul-tiple image points,the energy of the image points is further weakened,and the pixel space occu-pied by the image points formed by multiple image points becomes larger,resulting in the inability to distinguish the adjacent star points that are too close.In order to establish the star list suitable for interferometric star sensor,by setting the threshold of angular distance,the list is screened for the first time,and dark stars,variable stars and binary stars with too close angular distance are excluded.In order to ensure the uniformity of the catalog,Fibonacci grid points are used as spher-ical reference points,and the secondary screening of the catalog is carried out based on the refer-ence points.The result shows that the number of stars is small and the uniformity is good,which can meet the demand of interferometric star sensor.关键词
