Other AbstractTo visualize the detection area of the satellite scientifically,a virtual Celestial Sphere that can be rasterized for visualization is needed. Then a subdividing-mapping method is proposed in this paper. In the method,Graticules and HEALPix are used to subdivide and encode the Celestial Sphere,based on which the coverage area can be visualized according to the encoding number by projecting the texture to the 2D Celestial Sphere coordinate. Meanwhile,the method can adaptively generate the different texture images of the different sizes to fit the different subdivision levels without adding extra vertexes while the grade of the subdivision level rises,which can meet the real-time requirement in space science missions. Lastly,the proposed method is checked with the simulating data of the HXMT satellite and the real data of the DAMPE satellite launched in December 2015.
