摘要
分析了再入飞行器高速飞行所面临的环境特点及等离子鞘套产生的原因,研究表明等离子鞘套的存在会造成电磁波的衰减,对于INS/GNSS组合导航会产生较大的影响,提出了通过INS/GNSS紧耦合方法提高复杂环境下组合导航抗干扰能力,经分析这一技术有效。
The characteristics of flight environment of reentry vehicle and the generated reason of plasma sheath are analyzed,the research approved that the transmission of the electromagnetic wave can be declined by the plasma sheath and a strong impact on the integrated navigation based INS / GNSS will be made. An approach based on INS / GNSS tightly coupled js proposed to enhance the anti-interference ability in the complex flight environment.
