【摘要】 卫星通信作为现在及将来互联网及其他通信网的一个重要部分，它的通信性能的好坏对于我们日常通信及其他领域的影响日益突出。空间链路是整个卫星通信网络的关键。鉴于其实际操作的复杂性、不可修复性及昂贵造价，我们可以通过空间链路仿真来模拟星地与星间通信链路传输能力，验证星地与星间通信协议，星地与星间通信传输能力。为卫星通信的现实应用起到一定参考作用。本文将分布交互式仿真技术与半实物仿真技术相结合，既有利于提高仿真系统的可重用性、互操作性，也增强了仿真的可靠性与置信度。本文通过对卫星移动通信信道的分析和模型分析，给出了一套完整的空间链路仿真系统的设计与实现。重点给出了软件仿真的实现，并对硬件实现给了初步的设计思路。并利用卫星仿真工具包STK进行实时视景显示，使得空间链路的整个仿真过程更加形象。更多还原

【Abstract】 Satellite communication is an important part of the Internet and other communications, the quality of satellite communications have become increasingly prominent in communication and other fields.Space communication link is the key of satellite communications. Because of the complexity of its actual operation, and an expensive repair costs, we can use the way of simulation to simulate space satellite link with the satellite communication link transmission capability star certification agreement with the satellite communication, satellite communication and satellite jamming and anti-jamming capability. The thesis hopes to plays a certain reference role for the practical application of satellite communications.The technology which combines the Distributed Interactive Simulation technology and the Hardware-in-Loop Simulation technology can improve the reuse and the interoperability of the system. Also, this can improve the reliability of the simulation.Based on the analysis and the satellite communication channel model, A complete set of system design and implementation of space communication link simulation is given in this thesis. The focus of the system is software simulation, it gives the preliminary design of hardware simulation. And the use of satellite tool kit (STK) for real-time vision simulation, It finely images the whole simulation process.更多还原
