At 11:19 on November 6, the world's first 6G test satellite "University of Electronic Science and Technology" carried the Long March 6 carrier rocket successfully launched from the Taiyuan Satellite Launch Center in Shanxi Province, China, and successfully entered the scheduled orbit.


The "University of Electronic Science and Technology" satellite weighs 70 kilograms and is jointly developed by the University of Electronic Science and Technology of China, National Star Aerospace and Micro Nano Star. The satellite carries the terahertz satellite communication payload designed and developed by the University of Electronic Science and Technology of China and National Star Aerospace. Establishing a transceiver link on a satellite platform and carrying out a terahertz load test will also be the world's first technical verification of terahertz communication in a space application scenario.


It has the advantages of abundant spectrum resources, high transmission rate, and easy integration of communication perception. It has important application prospects in the field of terrestrial and space communication and is one of the key technologies of 6G networks.


Professor Xu Yangsheng, academician of the Chinese Academy of Engineering and director of the Academic Committee of the Institute of Satellite Industry Technology of the University of Electronic Science and Technology of China, said that the world's first 6G network test satellite developed and launched this time is the first technical verification of terahertz communication in space application scenarios.


Professor Chen Zhi, deputy director of the Key Laboratory of Terahertz Technology of the Ministry of Education and head of the Pilot Demonstration Site of Terahertz Communication Research at the University of Electronic Science and Technology of China, said that the terahertz test satellite developed this time has core components in the terahertz frequency band and terahertz communication systems. In this regard, the technical research has been completed, especially under the extremely harsh constraints of the space load, the technical problems such as miniaturization and low power consumption have been solved.


The "Electronic Science and Technology University" satellite will also be used for smart city construction, disaster prevention and mitigation, land planning, environmental protection, monitoring of major infrastructure construction, and serving national strategies and economic and social development in space.
