Design of hign precision space-borne Point-target trajectory tracking system

摘要:

一种高精度星载点目标轨迹跟踪系统,利用拟合点目标轨迹曲线的方法将点目标位置数据简化成多项式系数的数据包,由地面测控系统发送至星上遥感器指向控制单元。指向控制单元与时间管理单元解析数据包中时间参数与系数参数,控制指向镜机构进行运动,对点目标轨迹进行自主跟踪。此方法提高了跟踪系统的跟踪精度,减轻了目标跟踪时总线通信压力。经过试验验证,系统的跟踪精度远优于传统的目标跟踪方法,可进行推广使用。

Abstract:

High precision space-borne Point-targer trajectory tracking system,the point target position is simplified into a data packet with polynomial coefficients,which is sent to the satellite remote sensor pointing control unit from the ground control system.The pointing control unit and time management unit analysis time parameter and coefficient parameter in data packet,and control pointing mirrior mechanism for motion,autonomous tracking point target trajectory.This method improves the tracking accuracy of the tracking system,reduce the pressure of bus communication.The tracking accuracy of the system is much better than that of the traditional target tracking method.
