摘　　要：针对飞行器在级间分离点、关机点、头体分离点等特殊时段附件的弹道,飞行器的运动变化较其他时段剧烈,此时飞行器的加速度在很短的时间内会发生较大的变化,用三次多项式表示轨道带来较大误差的问题。在分析遥测脉冲数与飞行器受力关系的情况下,结合遥外测数据工程背景,提出利用遥测脉冲数搜索样条节点求解轨道特征参数的方法,对解决特殊段轨道参数表示不精确,准确求解轨道参数更具有现实意义,提高了特殊段内弹道的解算精度。For the trajectory of the aircraft at special time accessories such as the separation point between stages,the shutdown point,and the head separation point,the movement of the aircraft is more intense than other times,the acceleration of the aircraft will change considerably in a short time,the use of cubic polynomials to denote the orbit will bring about a great deal of error.In the analysis of the relationship between the number of telemetry pulses and the force of the aircraft,combined with the background of remote data engineering,a method of calculating orbit characteristic parameters by using telemetry pulse search spline node is presented,it is of practical significance to solve the imprecise expression of orbit parameters of special section,and to solve the orbit parameters accurately,improving the calculation precision of the interior ballistics in the special section.
