摘要
介绍了利用中继卫星系统进行运载火箭遥测数据传输的基本原理,对箭载终端链路增益进行了分析计算,通过分析箭载天线跟踪特性得出了天线指向角,在满足链路指标和该指向角的条件下,可以完成遥测数据传输,这些结论可以为工程应用提供参考。
The principle of telemetry data transmission of launch vehicle by relay satellite system is introduced. The link parameters of onboard terminal are calculated and analyzed. By analyzing antenna tracking characteristics, the direction angle of antenna on board is deduced. When the requirements for the link parameters and the direction angle are met, the transmission of telemetry data can be accomplished. The conclusion gives a reference to engineering application.
