Our country is developing a new generation of communication satellites, which will become one of the important components of the 6G communication network

News on February 12, according to Xinhua News Agency, the Galaxy Aerospace Ark Laboratory located in Haidian, Beijing, is developing a new generation of communication satellites. This new generation of communication satellite has both an antenna that can communicate and solar cells that can convert solar energy into satellite energy on a plane of several square meters. It is a communication satellite that integrates a phased array antenna and a solar wing. . Note: Xinhua News Agency did not display actual photos of satellites and models, possibly because they are "too advanced and inconvenient to display." According to Zhang Shijie, chief scientist of Galaxy Aerospace, the above-mentioned key technology is called "wing array integration" technology. At present, the development team has completed the key technical research on the two-dimensional deployment of the "wing array integration" satellite and will continue to develop wing array integration. Research on key technologies such as array integrated efficient heat dissipation and distributed power supply. The report pointed out that by "hiding" the satellite antenna in the solar wing, the size and cost required by the satellite can be greatly reduced, and the networking efficiency of multi-satellite deployment can be improved. Currently, satellites are in the evolutionary stage from "super large old desktop computers" to "laptop computers". Flexible solar wings can make satellites with "super large energy" a reality, and the construction of space information highway networks is accelerating. Zhang Shijie said, "Facing the future, mobile phone direct connection satellite technology will be one of the important components of the 6G communication network, and satellites are expected to burst out more new applications for the public." According to previous reports, in July 2023 At 10:50 on the 23rd, my country successfully launched four satellites, Sixiang 01~03 and Galaxy Space Lingxi 03, using the Long March 2D carrier rocket at the Taiyuan Satellite Launch Center. The satellite successfully entered the scheduled orbit and the launch mission was a complete success.
