摘要
GPS卫星在现代信息化战争中的作用日趋重要。针对GPS的观测应用需求,以目前在轨的31颗GPS卫星为研究对象,分析GPS卫星轨道的特征,研究GPS卫星对地面系统的可见性。结合STK和Matlab软件进行仿真分析,为地面GPS观测系统的天线波束宽度、波束个数设计提供参考。
GPS satellites become increasingly important in the modern information war. Aiming at the re- quirement of GPS observation, the characteristic of GPS satellites orbits is analyzed, and the visibility of GPS satellites to ground system based on the 31 GPS satellites in orbit is diseussed. Visibility is simulated by STK and Matlab software, which can be used as reference for the design of antenna beam width and beam number of ground observation system.
