【摘要】 根据“北半球版世界地图”表示的概念,探讨了中国二代卫星导航系统的设计覆盖范围。指出其往东即向太平洋方向延伸的设计较合理,而往北极方向的延伸距离不足。此设计有可能影响二代卫星导航系统作用的发挥,建议增加中国及周边地区的覆盖范围。更多还原

【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.更多还原
