In the field of aerospace communication, there have long been pain points such as high cost of high-end equipment, large number of base station deployment, and core technology being constrained by people. The promotion of various satellite interconnection and millimeter wave communication projects has always been constrained by both cost and performance. Many commercial communication projects are difficult to deploy on a large scale due to the cost of terminal equipment reaching tens of thousands of yuan, and regional communication coverage can only rely on densely built equipment to maintain effectiveness. The communication research team of the First Academy of China Aerospace Science and Technology Corporation has targeted industry bottlenecks and collaborated with Shanghai Aerospace Electronics Co., Ltd. to deeply cultivate the core technology of metasurface electromagnetic control. After multiple rounds of principle testing and scheme iteration, they have successfully completed the development of functional samples recently, making this cutting-edge technology truly autonomous and controllable, and clearing key obstacles for the construction of next-generation communication infrastructure.

Breakthrough in cutting-edge communication core technologies

Metasurface electromagnetic control is a key technology supporting 6G communication and low orbit satellite interconnection. It has a wide range of applicable scenarios and can support various cutting-edge businesses such as commercial satellite communication millimeter wave base station communication relay intelligent detection, with broad market development space. In the past, domestic related equipment relied on external technological solutions, making it difficult to promote large-scale production and application. The successful development of this sample marks that China has mastered a complete independent technological system in this field and is no longer limited by external technology.

Bi directional optimization of performance cost

Under the same communication coverage standards, this technology can reduce the deployment scale of communication front-end equipment, improve regional communication coverage performance by more than 40%, and directly reduce equipment investment in a single scenario by 500000 yuan. The R&D team optimized the entire production process, reducing the mass production cost of satellite and millimeter wave communication terminals from tens of thousands of yuan to thousands of yuan, completely solving the long-term problem of difficult popularization and landing of high-end communication equipment.

Establish a complete engineering conversion link

The R&D team has completed the entire process of optimizing the principle verification scheme and sample trial production, creating a low-cost and high-efficiency technology transformation model. The entire R&D process has accumulated a wealth of practical experience and mature technological reserves, which can quickly promote mass production in the future, accelerate the technology's entry into the civilian and commercial markets, and help the domestic communication industry seize the opportunity for the development of next-generation information technology.Keywords: Metasurface Electromagnetic Control, 6G Satellite Communication, Aerospace Communication Technology

This technological breakthrough has opened up the channel for the civilian transformation of aerospace communication, which not only strengthens China's independent capabilities in the field of satellite communication 6G technology, but also significantly reduces the industry's landing threshold, providing solid technical support for the upgrading of national communication infrastructure and the development of commercial aerospace industry. Relevant technologies will gradually be put into various communication projects for practical application in the future.Editor/Li Xiaohua
