Application Study of Trajectory Tracking of Ascending Course Based on CSM From Spaceflight Mission

为了实时、准确地获取航天发射任务上升段轨迹飞行特性,采用"当前"统计模型(CSM)算法,建立了航天任务上升段轨迹的运动模型,分析了目标运动特性;采用美国航天任务中脉冲雷达获取的测量数据进行统计分析,确定了运动模型的有关参数,仿真分析了在航天任务上升段CSM算法的滤波跟踪性能.分析比较了CMS算法滤波处理前后的性能,试验仿真结果表明,CSM算法能够较好地完成航天任务中的测控数据滤波处理工作,满足运动轨迹处理显示和故障判决要求.

To obtain the flight performance of ascending course in spaceflight launch mission in real time and accurately,the CSM（Current Statistical Model）algorithm was applied,and the moving model was set up regarding the ascending course in the spaceflight mission,and the moving performance of the target was analyzed.The data measured by radar equipment in American spaceflight mission was analyzed statistically,and the correlative parameters of the moving model were confirmed.The filter tracking performance was studied with CSM during the spaceflight ascending course.The performance of CSM algorithm after filtering was compared with that before filtering.The test simulation result shows that it is better to handle the filter and processing mission of the measure and control data during the spaceflight mission with CSM,and it can satisfy the demand of processing,show and failure-decision of the moving trajectory.
