摘　　要：针对大角度机动条件下的火箭欧拉角姿态解算、连续性要求下的姿态角计算、星箭分离姿态计算等火箭飞行姿态相关问题,基于工程实际情况给出相应的解决办法,分析计算中存在的问题及应对措施,给出计算结果、对比情况及经验总结。研究结果对火箭姿态计算、卫星姿态分析等均有一定的参考价值。The rocket attitude sometimes has large-scale changing,which would perhaps lead to some problems when the Euler angle data are used.For example,there would be an exception in the Euler angle maneuver equation sometimes,the angle data maybe are discontinuous,the attitude calculation at the time of satellite-rocket separation is easy to go wrong.To deal with the problems caused by the large-scale changing scenario,some solutions are given,which are based on the real situations of the engineer and the analysis of existing problems.Then the results and their comparison are obtained,together with some experiences summarization.This paper is useful for the attitude calculation of the rockets and satellites.
