摘要
Abstract
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.关键词
