Design of a Data Distribution System for High Earth Orbit Satellites

In response to the demand of meteorological applications for high orbit satellite data distribution systems, a high orbit S-band downlink broadcast link system based on spread spectrum system is proposed through analysis and design of communication frequency band, link budget, communication system, user capacity, and anti-interference ability. This system has the advantages of strong anti-interference ability and low terminal power consumption. This study has reference significance for the design and deployment of data distribution systems for civil high orbit meteorological satellite.
