China SatNet's Guowang satellites link Arctic and Antarctic in video call
Per Chinese state media, a polar vessel used Guowang satellites for its highest-latitude link yet, narrowing a gap with Starlink.
what happened
Chinese state media report that the research vessel Xuelong, while in the Arctic Ocean, used China's domestically built Guowang broadband satellite constellation to hold a video call with China's Qinling Station in Antarctica on Aug. 3, the system's highest-latitude link to date. Over the following weeks the expedition transmitted more than 300 files totaling over 100 gigabytes and held more than 40 video conferences; Global Times reports peak speeds around 30 megabits per second and sub-one-second video latency, per Global Times and Sixth Tone, unverified, and describes the test as 'near-operational' rather than full commercial service, with Guowang still under construction toward a planned 12,992 satellites by 2035.
why it matters
Guowang is China's answer to Starlink, which already serves Antarctic research stations and polar shipping, so a working polar link narrows one of the few capability gaps left between the two networks. Polar coverage matters commercially for Arctic shipping routes, polar research logistics, and any government customer weighing a China-based alternative to US satellite connectivity.
