Key facts
- Chinese researchers used the Guowang satellite constellation for a call between the Arctic and Antarctic.
- This marks the first publicly reported test of the Guowang constellation.
- China is accelerating its development of low-Earth-orbit satellite constellations.
Polar researchers have utilized a Chinese satellite constellation, dubbed Guowang, to establish a satellite video call between the Arctic and Antarctic. This event represents the first publicly disclosed test of the Guowang constellation, which is positioned as a potential competitor to Elon Musk's Starlink service. State media highlighted the call as evidence of China's rapidly advancing satellite capabilities. Beijing has intensified its efforts in developing low-Earth-orbit constellations in recent years, particularly after Starlink demonstrated its utility in military applications. Chinese scientists are reportedly exploring countermeasures against Starlink, including lasers and stealth submarines, due to concerns that the network could be exploited for military confrontation and espionage. These concerns are amplified by Starlink's close ties to the U.S. intelligence and defense sectors, and Elon Musk's increasing political involvement.
