摘要

VSAT网是卫星通信网络的重要发展方向之一,因组网形式灵活和经济性等特点而被广泛应用。笔者简要介绍了VSAT卫星通信网络的优势,同时结合民用航空的用户需求,探讨如何组建VSAT卫星通信网络的拓扑结构和传输链路。以通信卫星为中继器,选择相应的多址协议,在多个地球站之间进行通信,实现"多址联接",从而获得较大的系统容量和较高的信道利用率。
        VSAT network is one of the important development directions of satellite communication network. It has been widely used because of its flexible and economical form. This paper briefly introduces the advantages of VSAT satellite communication network, and discusses how to construct the topology and transmission link of VSAT satellite communication network according to the needs of civil aviation users. With the communication satellite as the repeater, the corresponding multiple access protocol is selected to communicate among several earth stations to achieve "multiple access connection", so as to obtain larger system capacity and higher channel utilization.
