According to the latest news, APS Satellite Holdings Co., Ltd., which is controlled by China Aerospace Science and Technology Corporation, recently signed an agreement on the construction of a satellite communication system with the Shenzhen government. It plans to build China's first high-throughput broadband satellite communication system during the 13th Five-Year Plan period. According to reports, this high-throughput broadband satellite is tens of times more bandwidth than conventional communication satellites, but its cost is the same as that of conventional satellites. Once completed, it will be able to provide users with high-speed Internet anywhere and anytime outside of the congested terrestrial Internet lines. service.
According to the agreement, APT Satellite Holdings Co., Ltd. will establish the Asia-Pacific Satellite Broadband Communications (Shenzhen) Co., Ltd. with the support of the Shenzhen Municipal Government, and plans to launch the first high-throughput broadband satellite for the Asia-Pacific region by the end of 2018. The satellite will be launched in 2019. Operating service work. At the end of the thirteenth five-year plan period, two high-traffic broadband satellites will be launched to serve the Americas and Europe and Africa. In the next few years, they will form an all-weather, safe, reliable, autonomous and controllable global broadband satellite communications system. According to reports, the total investment of the project is close to 10 billion yuan.
Compared with traditional communication satellites, large capacity and low cost are the biggest advantages of high-throughput satellites. According to statistical data, the total capacity of a high-throughput satellite currently exceeds 100 Gbit/s, while the capacity of a traditional communication satellite is approximately one-tenth of this figure, but the cost of satellite construction, rocket launches, and post-maintenance is related to Traditional satellites are flat. The investment per Gbit/s has dropped to $4 million to $5 million, which is only 1/50 of that of a conventional FSS satellite. As a result, the bandwidth cost of a high-throughput satellite network can be comparable to that of a terrestrial network, but communication capacity is greatly increased.
Since 1994, Hughes has developed the world's first DirecPC satellite receiving system that can be connected to personal computers, enabling PC users to use the small-bore receiving antenna of live satellites to download high-capacity information on the Internet at high speeds. With the promotion of a number of international satellite communications companies, it has become an important part of the worldwide high-speed Internet. More strikingly, the proposal and implementation of the grand plan for a global broadband satellite communication system based on non-geostationary satellite constellation demonstrated the future of satellite communication technology in high-bandwidth, high-speed, and multimedia communication applications.
In recent years, with the vigorous development of China’s space industry and the remarkable achievements it has made in the world, the aerospace industry has become a representative industry of China's high-tech industry. In 2015, the National Medium- and Long-Term Development Plan for Civil Space Infrastructure released by China is an important part of China’s civil space infrastructure construction. Satellite communication has thus become a national strategic emerging industry. It can be predicted that China will usher in greater development and breakthrough in this area in the future.
