摘　　要：在通信卫星自动化在轨测试系统中,影响软件通用性的因素很多,其中之一是由于射频链路系统的复杂性和多样性。针对这个问题,具体地描述了在轨测试软件与射频链路紧耦合的原因,分析了在轨测试系统对射频链路的接口需求及系统的数据处理特点。在此基础上,建立了与测量频段无关的统一射频链路模型,有效地屏蔽了实际测试链路的个性特征。最后给出了采用.Net技术构建射频链路组件的方法。实践表明,利用该组件开发的在轨测试软件通用性良好。Many factors affect generalization of IOT （In-Orbit Test） software in automatic in-orbit test systems for communication satellites and one of those factors is complexity and diversity of RF （Radio Frequency） link systems providing transmit channels for test signals. To solve this problem, this paper describes the reason for close correla- tion of IOT software with RF links and analyzes IOT systems interface requirements on RF links and features of data processing. Furthermore, a unified RF link model without association of frequency band is established to effectively screen specific characteristics of physical RF links. Finally, a method is developed with . Net technology to build RF link components. Practical in-orbit tests for numerous satellites show that the IOT software with the developed RF link components has excellent general performance.
