EventIn late September, a Chinese research vessel in the Arctic held a video call with China’s Zhongshan station in Antarctica via the GuoWang low‑orbit satellite network. Latency stayed under one second and upload/download speeds reached about 30 Mbps. All four vessels of China’s 16th Arctic expedition were connected, marking the first independent polar link on Chinese hardware.
China conducted the first inter‑polar video call using its own satellite network, linking a research vessel in the Arctic Ocean with a station in Antarctica with sub‑one‑second latency and speeds around 30 Mbps.
China’s Guowang satellite network linked Arctic researchers on three Chinese polar expedition vessels with personnel at Antarctica’s Qinling Station via a video call that had under one‑second delay, showing the system’s early operational capability for independent polar communications.
