银河航天 Galaxy Space – is located 3rd Floor, Building B, Baosheng Plaza, No. 8 Heiquan Road, Haidian District, Beijing, China, People’s Republic of China… Galaxy space- Aerospace is One of China, People’s Republic of China’s leading satellite Internet solution provider and satellite manufacturer, and the first unicorn company in my country’s commercial aerospace field. The company is committed to independent research and development and low-cost mass production of communication payloads, core single machines, and satellite platforms. It has built internationally leading supporting development capabilities for communication payloads, core single machines, and solar wings in Xi’an, Chengdu, and Beijing, and is also building in Nantong. The new generation of satellite intelligent manufacturing factories has achieved mass production capabilities of hundreds of satellites.
【”Space Carpet”! Galaxy Aerospace] According to Xu Ming, founder, chairman and CEO of Galaxy Space , the new generation of communication satellites being developed by Galaxy Aerospace looks like a “space flying carpet”, with both The communication antenna also has a solar chip that can convert solar energy into satellite energy. It is a communication satellite that integrates a phased array antenna and a solar wing. The key technology is called “wing array integration”.
The antenna is the core part of the satellite communication system and a key factor in determining the quality of signal transmission. Using large antennas can increase the gain of signal reception and transmission, thereby improving communication quality. The “wing array integrated” satellite can have a large antenna area and a powerful energy system, which can make the satellite more powerful when transmitting signals. It will be used to support the broadband communication needs of future mobile phones directly connected to satellites.
At present, Galaxy Aerospace has completed key technical research on the two-dimensional deployment of the “Wing Array Integrated” satellite. Generally speaking, the satellite’s antenna or solar wing generally only expands in one direction (such as horizontally) when unfolded. The so-called two-dimensional expansion means that the satellite’s antenna and solar wing must be deployed in an orderly manner in both the horizontal and vertical directions. . In view of this configuration in which the size of the satellite platform and the phased array are reversed, the traditional satellite-arrow connection, compression and separation technology cannot be used. The technical team designed and completed an integrated release plan; for extremely large-area arrays, high deployment accuracy and deployment stiffness are required In order to meet the large requirements, the technical team has broken through technical challenges such as folding and compaction, two-dimensional orderly deployment in orbit, and slowing down the impact of deployment, and completed the development of key mechanisms suitable for the deployment of satellite giant antennas and solar wing integrated arrays, and will Continue to carry out research on key technologies such as wing array integrated efficient heat dissipation and distributed power supply.
Facing the future, Galaxy Aerospace will accelerate the research on key core technologies such as phased array antennas, on-board large energy sources, and digital processing loads, and work with the upstream and downstream of the industrial chain to tackle key problems to help the development of my country’s aerospace information industry and the construction of a powerful aerospace nation.
