Abstract：In terms of the conception represented by ‘a World Map in the edition for the Northern Hemisphere’ ,this paper discusses the designed coverage of the 2nd generation of China Satellite Navigation System.It is pointed that the design will be more reasonable if the range extends eastwords along the Pacific,while the distance will be short if it extends towards the North Pole.The design may limit the function of the 2nd generation of China Navigation System.Therefore we advance the suggestion about expanding the coverage to the regions around China.
