星光-惯性制导是一种复合制导体制,它能有效地提高弹道导弹的命中精度.首先建立了单星平台星光制导的测量模型与修正模型,提出了信息等量压缩的概念,研究了其基本原理.在此基础上,阐明了单星方案能够与双星方案达到同样精度的原理,为快速确定单星最佳测星方位提供了理论依据.最后分析了导航星偏离最佳星方位时的制导误差,并提出了一种补偿方法.
Star-inertial guidance is a composite guidance system, which can effectively improve the accuracy of ballistic missiles.First of all, the measurement model and the correction model of star-guided single-satellite platform are established, the concept of information equal-quantity compression is proposed, and the basic Principle.On this basis, the principle that single-satellite scheme can achieve the same precision with double-star scheme is clarified, which provides a theoretical basis for quickly determining the best single-satellite positioning. Error, and proposed a compensation method.
