摘要
卫星通信因其组网快捷且适用范围广等特点在各类通信系统中发挥着重要作用,合理利用卫星资源需进行卫星通信链路计算。详细介绍了卫星传输链路计算的过程,给出了关键参数的计算方法。通过实例计算并分析结果,为用户合理选择如改变天线大小或增益、选用合适的功率放大器等参数提供参考。
Satellite communication plays an important role in various kinds of communication sys- tems, due to its quickness in networking and its wide range of application. Making good use of satellite resources requires calculation of satellite link budget. The calculation process of satellite link budget is presented and the method for calculating key parameters is provided. An example is calculated and the results are analyzed. Results show that the technology can provide a ref- erence for selecting parameters, such as antenna sizes and gains, and the power amplifier for users.
