0    introduction

2020 The country will 5G Network and satellite Internet are included together “ New infrastructure ” Range , Integration of heaven and earth （ Star land ） Network and business integration has become a trend ;2017-2020 Mobile communication satellite （ Tiantong No.1, etc ）、 High throughput satellite （ Middle star 16 Number, etc. ）、 LEO satellites （ Hongyun / Swan goose ） Put into use one after another , At the same time, it is oriented to the industry 5G The Internet （ Based on microservice service architecture ） Successively put into commercial use . Different orbiting satellites have different characteristics , In time delay 、 postage 、 Provide differentiated services in terms of transmission capacity , High throughput solution to bandwidth constraints , Low orbit further solves the problem of low delay and low cost （ About high rail 1/5）.

With 5G And the continuous development and maturity of new satellite technologies and the strategic layout of the National Satellite Internet , As well as the increase in marine demand of the the Belt and Road strategy , How to integrate high, medium and low orbit and operator network resources and make full use of the high bandwidth of new satellites / Low latency advantage , Give play to the advantages of China as a maritime power , For fishing boats at sea 、 The interconnection between offshore islands and ground networks and the formation of an organic whole has become a hot spot and research trend .
