摘　　要：在介绍航天器实时落点估算的作用和实现原理的基础上,分析了采用"龙格—库塔"算法进行航天器实时落点估算的优势,提出了四阶"龙格—库塔"法实时计算航天器落点模型。该方法在保证航天飞行试验强实时性的前提下有效提高了航天器实时落点估算的精度,对确保成功地实施航天器安全控制和回收提供了科学的依据。On the basis of introducing functions and implementing principles of the real-time estimating aerocraft fall point , the paper discusses advantages and implementing method of adopting the four-steps Runge-Kutta algorithm to estimate the aerocraft fall point. The algorithm analysis has improved accuracy of the real-time estimating aerocraft fall point on the basis of meeting data processing, strong real-time need in the aerocraft flight test, providing scientific conclusion for ensu- ring flight safety control and reclaiming the aerocraft flight test.
