The first test of the domestic satellite system "GW Constellation" was successful, and the video call delay in the North and South Pole did not exceed 1 second.

Abstract:

According to CCTV News, during China’s 16th Arctic Ocean expedition,

the domestic satellite system successfully tested for the first time and achieved video calls across the North and South Poles with a video delay of no more than 1 second.

It is understood that this test used the China Star Network "GW Constellation", which is my country's first giant satellite Internet plan.

In this polar region test,

the system's maximum uplink and downlink rate was about 30Mbps. In addition to meeting the communication needs of polar scientific expeditions, the related equipment can also be used in emergency rescue, maritime communications and other scenarios.

This successful test of domestically produced satellite communication equipment

marks that our country has achieved independent controllable communication in polar regions, and the data does not leave the country, effectively ensuring data security.

According to data, the GW constellation is also my country's first aerospace integrated 6G satellite Internet plan, with an overall plan to deploy 12,992 satellites, divided into two sub-constellations, GW-A59 and GW-A2.

Among them, GW-A59 plans to deploy 6,080 satellites, mainly distributed in orbits below 500 kilometers; GW-A2 plans to deploy 6,912 satellites, with an orbital altitude of approximately 1,145 kilometers.

The entire constellation adopts a multi-layer orbit layout with orbital inclinations ranging from 30° to 85°, ultimately building a global satellite Internet network.

According to relevant plans, the GW constellation will complete the deployment of approximately 1,300 satellites by the end of 2029, and plans to complete the networking of all 12,992 satellites in 2035.
