| 摘 要： | 为了评估北斗区域系统在中国各个地区的覆盖情况,利用STK软件仿真建立"5GEO+5IGSO+4MEO"的北斗区域星座,并在中国全境范围内建立了13个虚拟观测站,计算了北斗区域星座在全球范围内的GDOP分布,并统计了所有虚拟观测站的GDOP值的大小。结果表明,目前的北斗星座足以全天候满足我国全境范围内用户定位导航需求。

| Abstract: | The author of this paper simulated the ＂5 GEO ＋ 5 IGSO ＋4MEO＂ regional BDS constellation by using STK software,and simulated 13 virtual stations around china territory. The distribution of GDOP all around global was calculated, and the exact value of GDOP in each virtual station was analyzed. It is pointed that positioning and navigating requests of users from every comer of china territory can be perfectly fulfilled under the right now navigation constellation of BDS. |
