摘要
微纳卫星由于轻小型化、紧凑化和任务多样化等特点,近年来得到快速发展。由于微纳卫星体积、重量、功耗和成本受限,其数传链路设计需要在性能和开销之间寻找最佳平衡。因此,结合工程实际,通过微纳卫星数传链路设计案例,提出了数传系统参数优选配置方案。同时,利用STK仿真软件,对接收仰角、星上天线波束宽度和有效传输时间等参数进行仿真优化,给出了高性价比的链路设计建议。
Micro-nano satellites,for their miniaturization,compactness and diverse tasks,develop rapidly in recent years.With the limited size,weight,power consumption and cost of micro-nano satellites,it is necessary to find the best balance of between performance and overhead in the design of data transmission link.Thus in the light of engineering practice and through the design case of micro-nano satellite data transmission link,the optimization scheme of parameter selection for digital transmission system is proposed.Meanwhile,by using STK simulation software,optimization on parameters including elevation angle,satellites antenna beam width and effective transmission time is done.And finally the suggestion for cost-effective link design is given.
