近日,由设计院承担的中国电信国内卫星通信网五期扩容工程设计,分别在西宁和合肥顺利通过了由中国电信集团公司组织的专家会审,专家对该设计给予了高度肯定,一致认为该工程设计方案合理,设计技术新颖,该工程新建六面天线,并对28个已建地球站进行扩容,新增27000条卫星电话,组网方便,使用灵活,满足了用户站的需要。 随着卫星通信技术的不断发展,在卫星转发顺带宽保持不变的情况下,转发器的输出功率不断提高,如何合理利用卫生转发器和带宽资源显得越来越重要。传统的国内卫星通信网均受用QPSK/IDR通信方式,
Recently, the design institute of China Telecom satellite communication network to undertake five phase expansion project design, respectively, in Xining and Hefei successfully passed by the China Telecom Group experts organized the trial, the experts gave a high degree of recognition of the design, agreed that the project The design scheme is reasonable and the design technology is novel. The project newly built six-face antenna and expanded 28 completed earth stations, adding 27,000 satellite phones, convenient networking and flexible use to meet the needs of subscriber stations. With the continuous development of satellite communication technology, the output power of transponders keeps increasing while the bandwidth of satellite transponders remains unchanged. Therefore, it is more and more important to make rational use of the transponders and bandwidth resources. Traditional domestic satellite communications networks are subject to QPSK / IDR communications,
