基于高通量卫星技术特点的应用研究

Application research based on characteristics of high-throughput satellite technology

进入21世纪以后人类社会科学全面发展,高通量卫星诞生之后发展速度较快,自身具有较大容量,在应用过程中主要是应用多点波束频率复用形式,促使卫星传输容量不断提升。单位宽带成本较低,频率增速较快,卫星中各类资源是常规卫星资源的数十倍。近些年我国网络信息技术整体发展速度较快,在多个行业领域中广泛应用。文章通过分析信息网络基本应用特点可知,信息网络宽带化、多媒体化、泛在化特点较为明显。为了能适应宽带化发展要求,在卫星通信领域中逐步诞生了高通量卫星系统。与发达国家相比,我国卫星通信整体发展速度较为落后,多项应用技术需要从实践中不断完善。

After the 21st century, human society science has developed in an all-round way. After the birth of highthroughput satellites, it has developed rapidly and has a large capacity. In the application process, it mainly uses multispot beam frequency reuse to promote the continuous increase of satellite transmission capacity.. The unit broadband cost is lower, the frequency growth rate is faster, and the various resources in the satellite are dozens of frequency re. sources of the conventional satellite. In recent years, China’s network information technology has developed rapidly and is widely used in many industry sectors. By analyzing the basic application characteristics of information networks, the article shows that the characteristics of information network broadband, multimedia and ubiquity are more obvious. In order to adapt to the requirements of broadband development, high-throughput satellite systems have been gradually established in the field of satellite communications. Compared with developed countries, the overall development speed of satellite communications in China is relatively backward, and many application technologies need to be continuously improved from practice.
