微纳卫星测控系统链路预算与仿真

Link budgeting and simulation of micro-andnanosatellite measurement and control systems

为了解决微纳卫星通信设备的尺寸限制和功耗限制问题,提高测控链路传输性能和可靠性,建立了遥测预算模型和遥控预算模型,分析了传输链路的各个组成部分,并结合微纳卫星的特点对传输链路进行预算。通过对各个参数之间进行权衡,将链路裕度控制在合理范围之内,并通过仿真进行验证,为工程实践提供参考。

In order to solve the size limitation and power consumption limitation problems of micronano-satellite communication equipment,and to improve the transmission performance and reliability of measurement and control link,telemetry budget model and remote control budget model are established,and each component of the transmission link is analyzed and budgeted in combination with the characteristics of micronano-satellite.The link margin is controlled within a reasonable range by weighing cach parameter,and verified by simulation to provide reference for cngincering practicc.
