China has successfully tested its Guowang satellite constellation to provide low-Earth orbit (LEO) broadband connectivity in extreme environments. In late September 2026, researchers conducted a public test involving a video call between the Qinli Antarctic Station and three Arctic expedition vessels, including the Xuelong, Jidi, and Tanso-3.

Subsequent testing by the icebreaker Jidi during its 16th Arctic expedition verified network connectivity across the Arctic, the Antarctic, and the Qinghai-Tibet Plateau. This domestic satellite internet system demonstrated high-bandwidth, low-latency capabilities suitable for high altitudes and extreme weather. The mission utilized the network to transmit over 100GB of data and facilitate more than 40 high-definition video medical consultations, aiming to eliminate information isolation for China’s polar and maritime research.
