打击精度已经成为远程制导武器系统最重要的技术指标,提出了一种可以替代卫星导航的数据链导航系统,对

该系统的原理、实现、抗干扰、抗侦听进行了详细介绍,分析比较了该系统与惯导和卫星导航系统的误差。最后,得出了数据链

导航系统在武器装备精确制导中具有优势的结论。

-Precision has been the most important index to appraise a long-distance weapon under

control and guide. A combined navigation technique based on data chain is introduced to replace satellite

navigation system, including principle、realization、anti-jamming and anti-intercepting. After comparing the

system error with inertia and satellite navigation system, the advantage of data chain navigation system is

elicited.
