On October 19, according to Xinhua News Agency, it was learned from the "Jidi" ship, which is carrying out China's 16th Arctic Ocean scientific expedition mission, that the ship had completed the quasi-operational application test of domestic satellite internet on the Arctic route. This voyage successfully carried out networked communication verification in the Arctic, Antarctic, and Qinghai-Tibet Plateau for the first time, opening up the "last blind zone" of global communications. This marks that the extreme-environment communication support capability of domestic satellite internet has been empirically verified.
This test was jointly advanced by units including the Polar Research Institute of China (Chinese Polar Research Institute). In the video link among the "Jidi" ship, Qinling Station, Lhasa Lake in Tibet, and the Beihai Bureau, voice and video were clear and smooth. The communication achieved global low latency and high bandwidth, verifying the stability of the system operating under harsh environments such as extreme low temperatures, high altitude, strong wind and sand, and ice fog.
This voyage also realized, for the first time, polar remote online medical support via domestic satellite internet. In response to an expedition member's sudden illness, the domestic satellite internet broadband network was used to conduct ship-to-shore high-definition video consultation with relevant hospitals and experts in Qingdao. The consultation promptly conducted a comprehensive assessment of the condition, supported polar remote online medical care, and built a polar "lifeline."
In terms of data and business applications, this voyage, based on domestic satellite internet communication technology, cumulatively sent and received more than 300 files, with a data volume exceeding 100GB, and supported more than 40 video conferences. Related applications covered scenarios such as file transmission and video conferencing. These data provided a direct basis for communication support throughout the voyage.
This voyage completed full-scenario communication tests including voice calls, large-data-volume file transmission, ship-to-shore video conferencing, localization of survey equipment data transmission, and full-process online operation of the forecasting platform. The tests improved the current "information island" situation of polar expeditions. At the same time, they verified the full-voyage communication support capability based on domestic satellite internet.
From the perspective of impact, this verification accumulated experience and provided empirical support for the comprehensive realization of domestically produced communication support for China's polar expeditions and marine equipment. The domestic satellite internet achieving networked communication in the Arctic, Antarctic, Qinghai-Tibet Plateau, and other regions helps improve the communication efficiency and safety of polar scientific research, marine surveys, and telemedicine. This demonstrates its potential to serve polar expeditions and marine equipment communication support in extreme environments.
Looking to the future, as the domestic satellite internet communication system continues to be verified and applied in extreme environments, the "last blind zone" of global communications is expected to be further covered. Related experience may provide a more solid technical foundation for China's polar expeditions and the domestically produced communication support for marine equipment. The full-voyage communication support capability of domestic satellite internet will also be tested in more missions.
