China achieves satellite internet connectivity across Arctic, Antarctic, and Tibetan Plateau

The Chinese icebreaker Jidi, currently conducting its 16th Arctic expedition, has successfully completed pre-operational testing of a domestically developed satellite internet system. This achievement marks the first time network connectivity has been verified between the Arctic, the Antarctic, and the Qinghai-Tibet Plateau, effectively bridging what has been described as the last major communication gap in global coverage.

The testing demonstrated high-bandwidth, low-latency communication capable of operating in extreme environments characterized by low temperatures, high altitudes, and heavy fog or sandstorms. Key applications during the mission included remote online medical consultations via high-definition video between expedition members and hospitals in Qingdao, as well as the autonomous data transmission from domestic oceanographic drifting buoys.

According to the expedition team organized by the Ministry of Natural Resources, the mission utilized the satellite network to transmit over 100GB of data and more than 300 files, supporting over 40 video consultations. This development aims to eliminate information isolation during polar research and provides a foundation for fully localized communication support for China's polar and maritime expeditions.
