Accelerate the construction of the "One Network in Heaven and Earth" and achieve engineering breakthroughs in a batch of key satellite communication technologies

In recent years, China has been accelerating the deployment of satellite internet by launching tens of thousands of communication satellites into low Earth orbit, building a high-speed broadband network that covers the entire globe. It can be widely applied in remote area broadband access, maritime and aviation communications, emergency rescue, and other diverse scenarios. Which key technologies will connect this network? How will the industry layout related products and break through core technologies? In the production workshop of a satellite company, a star-mounted microwave antenna that is about to be delivered is testing coverage range and signal strength. A golden panel is one of the core payloads that determine whether the satellite can serve a large number of ground users simultaneously—phased array antenna. (CCTV News)
