摘要
Abstract
Atmospheric refraction model and data mode are important compositions in the whole starlight autonomous navigation scheme.According to the light tracing method,an atmospheric refraction model considering atmospheric inhomogeneous is proposed.The data base of the refraction model is the global three-dimensional grid atmospheric profile mode based on measured profile data.Additionally,the difference between the new refraction model and the conventional one which is based on the exponential atmospheric profile model at a single point is analyzed.The result indicates that the theoretical precision of the new model is higher than the conventional one for considering atmospheric inhomogeneous.关键词
