The Jidi research vessel successfully completed testing for a domestic satellite internet system during China's 16th Arctic expedition. The project established network connectivity across the Arctic, Antarctic, and the Qinghai-Tibet Plateau, effectively eliminating global communication blind spots.
The system demonstrated stable performance under extreme conditions, including low temperatures, high altitudes, strong winds, and ice fog. During the tests, the network supported clear video and audio connections between the Jidi vessel, the Qinling Station, Lhasa, and the North Sea Bureau.
The satellite network enabled the first remote online medical consultation for polar expeditions. Experts from Qingdao conducted high-definition video diagnostics for a crew member, providing critical medical support during the mission.
Throughout the expedition, the system handled over 300 files and transferred more than 100GB of data. It also supported over 40 video conferences, ensuring continuous operation of forecasting platforms and equipment data transmission with latency under one second.
