分析和实验表明,在低业务量卫星通信系统中,用SCPC-DAMA技术能最大限度地节省空间段和地面站的费用(在相同的业务量下,与预分配系统比较)。本文从我国国情出发,采用混合控制方式,设计和实现了SCPC-DAMA卫星通信系统,并对其性能进行了分析和计算机模拟。在此基础上完成了一个主DAMA控制器和三个分站DAMA控制器及用户接口设备的研制。经系统联试证明达到了各设计要求,各DAMA控制器工作正常。混合控制式SCPC-DAMA系统特别适合于稀路由国内卫星通信区域网或专用网。
Analysis and experiments show that in low-traffic satellite communications systems, SCPC-DAMA can save space segment and ground station to the maximum cost (compared with pre-distribution system under the same traffic volume). Based on our national conditions, this paper designs and realizes the SCPC-DAMA satellite communication system by hybrid control method, and analyzes its performance and computer simulation. On this basis, completed a master DAMA controller and three sub-station DAMA controller and user interface device development. Proved by the system to meet the design requirements, the DAMA controller is working properly. Hybrid control SCPC-DAMA system is particularly suitable for thin-routing by the domestic satellite communications area network or private network.
