| 摘 要： | ＂北斗二号＂卫星导航定位系统（简称BD-2）是我国自主研制的新一代卫星导航系统。基于STK软件建立了BD-2的星座模型,并着重从星座的整体覆盖性能、对于我国境内及我主要战略方向的覆盖情况、星座中三种卫星对于GDOP的影响情况和星座的冗余性四个方面进行了仿真分析。针对仿真分析中发现的问题和不足,提出了完善BD-2的几点建议。

| Abstract: | BD-2 is a new-generation satellite navigation and positioning system independently developed by China.The constellation model of BD-2 is established on the basis of STK.The whole coverage capability of the constellation,the coverage of China territory and main strategic direction,the effect to the GDOP by three kinds of satellites in the constellation and the redundancy of the constellation are simulated and analyzed.For the deficiency and problems found in the simulation,some ideas on how to improve the pr... |
