地面测试阶段通过发送遥控指令对卫星的功能、性能进行全面验证.其中机构运动、火工品起爆、阀门的开关等测试项目对指令执行时间有严格要求,因此,需要准确测量遥控指令传输时延,精确控制遥控指令执行时间.针对上述问题,提出了一种利用网络封包分析软件(Wire-shark)结合综合基带设备(Cortex)测试遥控指令传输时延的测试方法,分别测量网络通道设备时延和射频通道设备时延,分析了测试误差,该方法操作简单,精度高,可为其他卫星遥控指令传输时延的测量提供参考,具有工程实践意义.
Telecommand Transmission Delay Test Method for Satellite
During the ground test phase,telecommand are utilized to comprehensively verify the functionality and performance of satellite.Test objectives such as mechanism movement,explo-sive initiating,valve opening and closing,impose strict requirement on telecommand execution time.Therefore,it is imperative to accurately measure the transmission delay of telecommand,also precisely controll their execution time.In view of above problems,this paper presents a measurement method that employs Wireshark and Cortex to precisely measure the transmission delay of telecommand,the transmission delay as Network channel equipment and RF channel e-quipment were measured,measurement error are analyzed.The method is distinguished by its simplicity,high precision.It offers valuable insights into measuring the transmission delay of telecommand for other satellites,thus holding practical significance in engineering applications.
