【 摘 要 】

Because of the rapid development of small satellite technology and the advantages of low earth orbit satellite (LEO) satellites compared with traditional geosynchronous orbit satellite (GEO) satellites such as low time delay low propagation loss broadband, LEO constellation satellite communication system has gradually become one of the hot spots in the field of satellite communication. At present, many countries and satellite communication companies in the world are working on broadband satellite communication system programmes. In view of the actual needs of our country, through link computation and comparing the complexity of satellite implementation at different communication elevation angles to meet the terminal rate requirements, the assumption of constructing broadband LEO constellation satellite communication system with high elevation is put forward. The transmission characteristics of OneWeb constellation are simulated by STK and Matlab simulation software.
