战术弹道导弹飞行环境中GPS卫星可用性探讨

Investigation on Availability of GPS Navstar in the Flight Environment of Tactical Ballistic Missile

系统地分析了在战术弹道导弹飞行环境下，如何选择可用来参与弹道导弹组合制导的 ＧＰＳ 卫星的准则。探讨了提高弹载接收机的抗干扰能力的方法．针对战术弹道导弹标准飞行弹 道，利用实测卫星星历进行了仿真，给出了仿真结果．

How to select GPS navstars which can be used in integrated guidance in the flight environment of tactical ballistic missile is discussed in the paper, and how to improve antijamming ability of GPS receiver is also discussed preliminarily. The simulations have been carried out by using reference trajectory of TBM and measured navstar ephemeris,and the simulation results are given.
